UNICEF, 2011White Paper | Science and Impacts Program. Extreme Weather and Climate Change : understanding the Link, Managing the Risk
Typically, climate change is described in terms of average changes in temperature or precipitation, but most of the social and economic costs associated with climate change will result from shifts in the frequency and severity of extreme events.[1] This fact is illustrated by a large number of costly weather disasters in 2010, which tied 2005 as the warmest year globally since 1880.[2] Incidentally, both years were noted for exceptionally damaging weather events, such as Hurricane Katrina in 2005 and the deadly Russian heat wave in 2010. Other remarkable events of 2010 include Pakistan’s bigge ...
TCP. WMO/ESCAP Panel on Tropical Cyclones - Thirty-eighth session : final report
World Meteorological Organization (WMO) ; Economic and Social Commission for Asia and the Pacific (ESCAP) - WMO, 2011The impact of climate change on global tropical storm damages
This paper constructs an integrated assessment model of tropical cyclones in order to quantify the impact that climate change may have on tropical cyclone damages in countries around the world. The paper relies on a tropical cyclone generator in each ocean and several climate models to predict tropical cyclones with and without climate change. A damage model is constructed to compute the resulting damage when a cyclone strikes each country. Economic development is expected to double global tropical cyclone damages because more will be in harm's way. Climate change is expected to double global ...

The analysis in this paper is based mainly on interview data collected in two sites in Afar as well as insights from past studies in the region as documented in published literature. Some of the key issues identified for Afar are followed u ...
Attribution of Weather and Climate-Related Extreme Events
Unusual or extreme weather and climate-related events are of great public concern and interest, yet there are often conflicting messages from scientists about whether such events can be linked to climate change. There is clear evidence that climate has changed as a result of human-induced greenhouse gas emissions, and that across the globe some aspects of extremes have changed as a result. But this does not imply that the probability of occurrence (or, given a fixed damage, risk) of a specific type of recently observed weather or climate event has changed significantly as a result of human in ...WorldRiskReport 2011 : Focus - Governance and civil society
United Nations, 2011Earthquakes, floods, droughts, storms: disasters seem to occur unexpectedly and with unimaginable force. But why do some countries better succeed than others to cope with extreme natural events? The WorldRiskReport 2011 helps to evaluate the vulnerability of societies to natural hazards. On behalf of Alliance Development Works, UNU-EHS has developed the WorldRiskIndex and calculated risk values for 173 countries worldwide.

Journal of the Meteorological Society of Japan, Vol. 88. No 4. Yamasaki Masanori - Meteorological Society of Japan, 2010A numerical model in which the effects of cumulus convection are incorporated as the subgrid-scale and mesoscale organized convection is resolved by the grid (mesoscale-convection-resolving model, MCRM) was developed in the 1980s with an intention of improving the parameterization schemes for moist convection, which had been used since the 1960s. As in many numerical models with parameterization in the 1980s, hydrostatic equilibrium was assumed. The present paper describes a nonhydrostatic version of the MCRM, with some modifications of the subgrid-scale effect formulation used in the hydrosta ...Terrain Effects on an Afternoon Heavy Rainfall Event, Observed over Northern Taiwan on 20 June 2000 during Monsoon Break
Journal of the Meteorological Society of Japan, Vol. 88. No 4. Chen Ching-Sen; Liu Che-Ling; Yen Ming-Cheng - Meteorological Society of Japan, 2010An afternoon heavy rainfall event in northern Taiwan, observed on June 20, 2000 during the monsoon break, is investigated using surface observation and Doppler radar data and a nonhydrostatic model with a horizontal grid spacing of 1.33 km. Heavy rainfall was brought majorly by two precipitation systems, namely A and B. System A was initiated and developed in Taipei Basin, associated with a local wind convergence line. System B was formed on the western slopes south of Taipei Basin, extended northward of the Taipei Basin, and lasted for 4 h. The formation and maintenance mechanisms of the two ...Simulation of the Bare Soil Surface Energy Balance at the Tongyu Reference Site in Semiarid Area of North China
The performance of a 1-D soil model in a semiarid area of North China was investigated using observational data from a cropland station at the Tongyu reference site of the Coordinated Enhanced Observing Period (CEOP) during the non-growing period, when the ground surface was covered with bare soil. Comparisons between simulated and observed soil surface energy balance components as well as soil temperatures and water contents were conducted to validate the soil model. Results show that the soil model could produce good simulations of soil surface temperature, net radiation flux and sensible he ...Further Study of Typhoon Tracks and the Low-Frequency (30-60 Days) Wind-Field Pattern at 850 hPa
Atmospheric and Oceanic Science Letters, Volume 3 Number 6. Tian Hua; Li Chong-Yin - Science Press, 2010The association of typhoon tracks over the western Pacific with the low-frequency wind-field pattern of atmospheric intraseasonal (30-60 days) oscillation at 850 hPa is further studied by using observational data analyses. Comparative analyses of the composite wind fields at 850 hPa, contrasting the atmospheric intraseasonal oscillation (ISO) with the original circulation, show that the typhoon tracks are closely related to the wind pattern of the ISO but are not obviously related to the original wind fields. Case studies of two typhoons in 2006 also show that the low-frequency wind-field patt ...Preliminary Study of Sensitive Areas for Several Tropical Cyclone Track Prediction Cases in 2007
Atmospheric and Oceanic Science Letters, Volume 3 Number 6. Tan Xiao-Wei; Wang Dong-Liang - Science Press, 2010Conditional nonlinear optimal perturbation (CNOP) obtained by the ensemble-based calculation method is employed to find possible sensitive areas for improving 48-h or more than 48-h tropical cyclone (TC) track predictions in several cases affecting China in 2007. These sensitive areas are examined by observing system simulation experiments (OSSEs). Results show that these sensitive areas improve TC track predictions for 48 h or more to different extents. Further analysis is performed to determine the distribution characteristics of sensitive areas in these cases. Results show that areas south ...Vol. 88. No 3 - June 2010

Journal of the Meteorological Society of Japan, Vol.88 No.5. Ma Lei-Ming; Tan Zhe-Min - Meteorological Society of Japan, 2010A new scheme, termed Vortex Initialization with the Assimilation of Retrieved Variables (VIRV), is presented to improve the initialization of regional numerical model for Tropical Cyclone (TC) prediction. In this scheme, the horizontal winds in Planetary Boundary Layer (PBL) and the sea level pressure (SLP), retrieved from Quick Scatterometer (QuikSCAT) data obtained using a modified University of Washington Planetary Boundary Layer (UWPBL) model, are assimilated with a cycled three-dimensional variational (3DVAR) technique to produce the initialized analysis. The procedures of retrieval are i ...Temporal Variations of the Frontal and Monsoon Storm Rainfall during the First Rainy Season in South China
Atmospheric and Oceanic Science Letters, Volume 3 Number 5. Yuan Fang; Wei Ke; Chen Wen; et al. - Science Press, 2010The temporal variations in storm rainfall during the first rainy season (FRS) in South China (SC) are investigated in this study. The results show that the inter-annual variations in storm rainfall during the FRS in SC seem to be mainly influenced by the frequency of storm rainfall, while both frequency and intensity affect the inter-decadal variations in the total storm rainfall. Using the definitions for the beginning and ending dates of the FRS, and the onset dates of the summer monsoon in SC, the FRS is further divided into two sub-periods, i.e., the frontal and monsoon rainfall periods. T ...A Comparison Study of the Contributions of Additional Observations in the Sensitive Regions Identified by CNOP and FSV to Reducing Forecast Error Variance for the Typhoon Morakot
The sensitive regions of conditional nonlinear optimal perturbations (CNOPs) and the first singular vector (FSV) for a northwest Pacific typhoon case are reported in this paper. A large number of probes have been designed in the above regions and the ensemble transform Kalman filter (ETKF) techniques are utilized to examine which approach can locate more appropriate regions for typhoon adaptive observations. The results show that, in general, the majority of the probes in the sensitive regions of CNOPs can reduce more forecast error variance than the probes in the sensitive regions of FSV. Thi ...Marine Atmospheric Boundary Layers Associated with Summer Monsoon Onset over the South China Sea in 1998
Atmospheric and Oceanic Science Letters, Volume 3 Number 5. Wang Dong-Xiao; Zhou Wen; Yu Xiao-Li; et al. - Science Press, 2010The variations of the marine atmospheric boundary layer (MABL) associated with the South China Sea Summer Monsoon were examined using the Global Positioning System (GPS) sounding datasets obtained four times daily during May-June 1998 on board Research Vessels Kexue 1 and Shiyan 3. The MABL height is defined as the height at the lowest level where virtual potential temperature increases by 1 K from the surface. The results indicate that the MABL height decreased over the northern South China Sea (SCS) and remained the same over the southern SCS, as sea surface temperature (SST) fell for the no ...Analysis of South Asian Monsoons within the Context of Increasing Regional Black Carbon Aerosols
Atmospheric and Oceanic Science Letters, Volume 3 Number 4. Mahmood Rashed; Yao Jin-Feng - Science Press, 2010South Asian monsoons were analyzed within the context of increasing emissions of black carbon (BC) aerosols using a global atmospheric general circulation model. The BC aerosols were allowed to increase only over the south Asian domain to analyze the impacts of regional black carbon over the climatological patterns of monsoons. The black carbon significantly absorbed the incoming short wave radiation in the atmosphere, a result that is consistent with previous studies. Pre-monsoon (March-April-May) rainfall showed positive anomalies, particularly for some coastal regions of India. The summer ( ...Possible Impact of the Boreal Spring Antarctic Oscillation on the North American Summer Monsoon
This study examined the relationship between the boreal spring (April-May) Antarctic Oscillation (AAO) and the North American summer monsoon (NASM) (July-September) for the period of 1979-2008. The results show that these two systems are closely related. When the spring AAO was stronger than normal, the NASM tended to be weaker, and there was less rainfall over the monsoon region. The opposite NASM situation corresponded to a weaker spring AAO. Further analysis explored the possible mechanism for the delayed impact of the boreal spring AAO on the NASM. It was found that the tropical Atlantic s ...Volume 3 Number 4 - 16 July 2010

Abstracts - International Workshop on Addressing the Livelihood Crisis of Farmers: Weather and Climate Services
The International Workshop on Addressing the Livelihood Crisis of Farmers: Weather and Climate Services is taking place at a time when there is a growing concern about livelihoods of over 500 million smallholder farmers around the world coupled with the increasing climate variability and future climate change. The world population is projected to grow from 6.5 billion today to 8.3 billion in 2030 and nearly 9.2 billion in 2050. All of that growth will be concentrated in developing countries. Global food production will therefore need to increase by more than 50% by 2030, and should nearly doub ...Natural Hazards, UnNatural Disasters : The Economics of Effective Prevention
World Bank, 2010Natural Hazards, UnNatural Disasters looks at disasters primarily through an economic lens. Economists emphasize self-interest to explain how people choose the amount of prevention, insurance, and coping. But lenses can distort as well as sharpen images, so the book also draws from other disciplines: psychology to examine how people may misperceive risks, political science to understand voting patterns, and nutrition science to see how stunting in children after a disaster impairs cognitive abilities and productivity as adults much later. It asks not only the tough questions, but some unexpect ...
WWRP, 04. WWRP 2010-4 - 2nd WMO International Workshop on Tropical Landfall Processes (IWTCLP-II)
Severe calamities and fatalities have arisen from landfalling tropical cyclones (TC) around the world in recent years, such as Morakot (August 2009) in western North Pacific, Nargis (May 2008) in Bay of Bengal, Gonu (June 2007) in North Arabian Sea, Bilis (July 2006) in western North Pacific, Katrina (August 2005) in Gulf of Mexico, and Catarina (March 2004) in South Atlantic etc. Transferring the advancements from the research community to operational forecast centers in NMHSs would be helpful for improving the landfalling tropical cyclone (LTC) forecasts and for mitigation of high-impact tro ...
PWS, 21. Guidelines on early warning systems and application of nowcasting and warning operations
In 2010, a historic heat wave and numerous wildfires impacted Moscow and surrounding areas in the Russian Federation. At the same time, catastrophic flooding from unusually heavy monsoon rains was ongoing in Pakistan. Both events led to many fatalities and considerable human suffering. As climate change due to anthropogenic forcing continues, extreme weather events such as these are likely to become more common (IPCC 2007), further increasing the need for preparedness and early warning systems.
The need for robust early warning systems goes beyond purely natural disasters and extend ...Investing in communities: the benefits and costs of building resilience for food security in Malawi : investing in disaster risk reduction activities in Malawi
This publication reports on a community-based cost benefit analysis of a disaster risk reduction (DRR) and food security programme in a Malawian agricultural community. The aim of this study is to assess programme activities for their cost-effectiveness and to gather evidence to help inform programming decisions taken by Tearfund, their partners and other NGOs. A second key aim is to inform policy-relevant recommendations to help convince governments, donors and UN agencies to act in a timely way and with appropriate interventions to address food insecurity, given the growing threat from droug ...1541. 1st WMO International Conference on Indian Ocean Tropical Cyclones and Climate Change

Guidelines for converting between various wind averaging periods in tropical cyclone conditions
World Meteorological Organization (WMO) ; Kepert Jeffrey David; Ginger J.D. - WMO, 2010 (WMO/TD-No. 1555)L’agroécologie en pratiques
Agrisud International, 2010L’agroécologie consiste pour le paysan à chercher à imiter la nature dans son champ. Elle mise sur les complémentarités entre différentes plantes et animaux. Elle conçoit l’agriculture non comme un processus qui transforme des intrants en productions agricoles, mais comme un cycle, où le déchet sert d’intrant, où les animaux et les légumineuses fertilisent les sols et où les mauvaises herbes sont considérées comme remplissant des fonctions utiles.Climate Change and Flow of Environmental Displacement in Bangladesh
Akter Tahera - Unnayan Onneshan, 2009This study depicts environmental displacement with the premise of increased frequency of natural disasters and the adverse impacts of climate change. Bangladesh is already experiencing recurrent floods, severe cyclones, water logging, salinity intrusions, droughts and river bank erosion which induce mass population displacement. There is no generally agreed definition and scientifically developed methodology to estimate environmental displacement. Proper development guidelines are yet to be adopted to protect the lives and livelihoods of the displaced people who have the right to expect safe l ...African monsoon multidisciplinary analyses: abstracts
African Monsoon Multidisciplinary Analyses (AMMA) is an international project to im-prove our knowledge and understanding of the West African monsoon (WAM) and its variability using a multi-scale approach; timescales ranging from daily over inter-annual to decadal and beyond and space scales reaching from local over mesoscale to regional and global.
AMMA is motivated by an interest in fundamental scientific issues and by the societal need for improved prediction of the WAM and its impacts on West African nations. Vulnerability of West African societies to climate variability is likely t ...Snowpack and Its Assessment
This module explores the science of snowpack and snowpack assessment. It begins by describing the factors involved in snowpack development and then focuses on snowpack evolution. Using two scenarios (one set in mountainous terrain, the other in a relatively flat area), the module explores how basic processes, such as conduction and radiation, and various precipitation events impact snowpack, particularly its density, structure, and stability, throughout the cold season. Woven throughout the module are video clips of avalanche forecasters discussing snowpack and demonstrating various assessment ...The Amazon Rain Forest and Climate Change
This module discusses global climate change that is occurring largely because of greenhouse gases emitted by human activities, and in particular the impact that tropical deforestation plays in the climate system. It also covers signs of climate change, the current thinking on future changes, and international agreements that are attempting to minimize the effects of climate change. The United Nations Collaborative Programme on Reducing Emissions from Deforestation and Forest Degradation in Developing Countries (UN-REDD Programme) is also discussed.Climate Change: Fitting the Pieces Together
This module discusses climate change, particularly as it is currently being affected by increasing concentrations of greenhouse gases emitted by human activities. It also covers signs of climate change, how scientists study climate, the current thinking on future changes, and what can be done to minimize the effects. Updated in 2012.Jason-2: Using Satellite Altimetry to Monitor the Ocean
Altimeters onboard satellites such as Jason-2 measure sea surface height and other characteristics of the ocean surface. These characteristics are linked to underlying processes and structures, making altimetry data useful for understanding the full depth of the global ocean. This 75-minute module explores major discoveries made possible by altimetry data in oceanography, marine meteorology, the marine geosciences, climate studies, the cryosphere, and hydrology. For example, altimeters have played a vital role in detecting and monitoring sea level rise and its relation to climate change. The m ...Distributed Hydrologic Models for Flow Forecasts - Part 1
Distributed Hydrologic Models for Flow Forecasts – Part 1 provides a basic description of distributed hydrologic models and how they work. This module is the first in a two-part series focused on the science of distributed models and their applicability in different situations. Presented by Dr. Dennis Johnson, the module begins with a review of hydrologic models, and then examines the differences between lumped and distributed models. It explains how lumped models may be distributed by subdividing the basin and suggests when distributed hydrologic models are most appropriate. Other topics cove ...
Flood Management Tool Series, Technical Document, 09. Flood Management in a Changing Climate
This tool is an initiator and starting point on how flood management can be an autonomous part of an adaptation strategy to climate change. Flood managers have vast experience in managing floods under current climate variability. Floods are among the most widely cited expected impacts of global warming, either with an increased frequency or with increased magnitude in particular regions. As such climate change poses an additional challenge that needs a conscious strategic reorientation of flood management practices towards applying risk management techniques and involving a far broader set of ...Regional climate change and adaptation : the Alps facing the challenge of changing water resources
EEA, 2009Drawing on the most recent knowledge of climate change impacts in the Alps and experiences across the region, this report analyses the risks that climate change presents to the region's water supply and quality, identifying needs, constraints, opportunities, policy levers and options for adaptation. It extracts policy guidance on adaptation practice and aims to assist regional and local stakeholders in developing robust adaptation strategies. The focus of the report is on water resources and related adaptation, rather than water-related extreme events like floods, avalanches, landslides or mud ...Climate Change and Humanitarian Action: Key Emerging Trends and Challenges
OCHA, 2009During the past century global temperatures increased by approximately 0.7 degrees Celsius. According to the Intergovernmental Panel on Climate Change (IPCC), the pace of climate change is now such that even in a ‘best-case’ scenario, further increases of at least 1 degree are expected by 2050. According to the IPCC, current emissions are already nearing the limit required in 2015 to keep warming below 2 degrees Celsius; the level UNDP defines as a “a reasonable and prudent long term objective for avoiding dangerous climate change”. In the absence of swift action to radically reduce gre ...
