La Chine se dote de systèmes d’alerte précoce axés sur les impacts et sur les risques
La Chine est l’un des pays les plus durement touches par les conditions meteorologiques. Entre 1984 et 2014, ces phenomenes ont provoque en moyenne, chaque annee, la mort de 4 066 personnes et des pertes economiques directes de 192,2 milliards de yuan (30,5 milliards de dollars E. U.) – 2 % du produit interieur brut (PIB). Le coefficient de perte annuel moyen (pertes economiques directes/ PIB annuel) est passe de 2,08 % au cours de la periode 1984–2000 a 1,03 % entre 2001 et 2014, grace a l’amelioration des mesures de prevention et d’attenuation des catastrophes. Meme reduit de moitie, ce coef ...

Vers une réduction substantielle des risques de catastrophes d’ici à 2030
Bulletin, Vol. 64(2). OMM, 2016Le Cadre de Sendai pour la reduction des risques de catastrophe (2015–2030) a ete adopte le 18 mars dernier; il s’agit du premier accord d’envergure signe au titre du programme d’action de 2015. Ses sept objectifs mondiaux et quatre priorites interessent particulierement l’OMM, qui a fait de la reduction des risques de catastrophe l’un de ses sept domaines d’action prioritaire. La protection des personnes, des moyens de subsistance et des biens est au coeur de la mission de l’Organisation – qui soutiendra donc le Cadre de Sendai par un large eventail d’activites scientifiques et techniques.
Climate and Water Resources Management, Part 1: Climate Variability and Change
Climate is changing at unprecedented rates in recorded history. A variety of lines of evidence demonstrate that climate change is likely to affect the hydrologic cycle and thus create new challenges in water management. This requires that climate change information be included in water and water-related resources planning, operations, and management. Climate and Water Resources Management, Part 1: Climate Variability and Change describes the terminology, global evidence, regional manifestations, and basic science of global climate variability and anthropogenic change, with a focus on water res ...

The learning is enhanced with rich graphics and periodic questions.
Best Practices in Tropical Cyclone Briefings
Crafting clear, concise and effective messages focused on customer needs is a crucial skill in every decision-support situation. Tropical cyclones that threaten a coastline have the potential to inflict devastating damage to communities and communicating relevant weather information will assist decision-makers in their plans and preparation work. This lesson examines how to effectively prepare for the hurricane season and then focuses on how best to support NWS partners through meteorological briefings during tropical cyclone events. Basic familiarity with probabilistic forecast guidance is re ...

GAW Report, 230. Airborne dust : from R&D to operational forecast : 2013-2015 Activity Report of the SDS- WAS Regional Center for Northern Africa, Middle East and Europe
The 18th WMO/IAEA Meeting on Carbon Dioxide, Other Greenhouse Gases, and Related Measurement Techniques (GGMT - 2015) took place from 13 to 17 September 2015 at the Scripps Institution of Oceanography in La Jolla (CA), USA. It was the 40 th anniversary of the first GGMT meeting (then called "CO 2 Experts Meeting") which was also held at Scripps in 1974. WMO has provided the framework for all carbon dioxide experts meetings since 1975. IAEA in Vienna joined WMO as a co - organizer in 1997 due to the increased use of carbon isotopes in studying the carbon cycle. The meeting reviewed current WMO ...
Variability of the West African summer Monsoon and its relation to the SSTA over the Atlantic Ocean
This study investigates spatial and temporal features of the West African Summer Monsoon (WASM) and its relation to the Sea Surface Temperature Anomaly (SSTA). The variability of the WASM from June to September was analyzed during the period 1960-2013, with methods including EOF analysis of the precipitation anomaly and SSTA and the associated large scale circulation pattern. The result from the first EOF-Mode of the precipitation anomaly which has the highest positive loadings over the region shows that during the summer, the precipitation anomalies are positives in the Sahel and the Sahara. ...

Drought Assessment Using SPEI and NDVI : Case of Lesotho
While drought conditions are generally a common and recurring phenomenon of the climate in Southern Africa especially Lesotho, the frequency of droughts in Lesotho has increased significantly over the past few years. Lesotho has suffered the devastating impacts of drought during the past several decades resulting in poor harvests and large livestock losses to rural farmers. The majority of the population in Lesotho engages with rain- fed agriculture and is dependent to some degree on own production for household food supply and/or cash income (Dejene, Midgley, & Marake, 2011). Any negative cha ...
Handbook of Drought Indicators and Indices
The purpose of this handbook is to cover some of the most commonly used drought indicators/indices that are being applied across drought-prone regions, with the goal of advancing monitoring, early warning and information delivery systems in support of risk-based drought management policies and preparedness plans. These concepts and indicators/indices are outlined below in what is considered to be a living document that will evolve and integrate new indicators and indices as they come to light and are applied in the future. The handbook is aimed at those who want to generate indicators and indi ...
Diagnosis Of Extreme Rainfall And Temperature Event Over Rwanda (1961-2010)
This study attempted to investigate the variability of extreme rainfall and temperature over Rwanda and the associated circulation anomalies forecasting on wet and dry rainfall events between 1961 and 2010. The datasets used to achieve the objectives includes Temperature, the rainfall dataset, wind vector, pressure vertical velocity (omega) and the Indian Ocean sea surface temperature (SST). The methods used include correlation analysis, Standardized anomaly, composite analysis, and Empirical Orthogonal Functions (EOF) analysis. The results show that the mean annual cycle depict two rainy Seas ...
The Sahel Drought Mechanism: insights from two contrasting extreme events
The Sahel drought mechanism: insights from two contrasting extreme events during boreal summer July-August-September (JAS) is investigated in this study using the standardized precipitation index (SPI). Empirical orthogonal function (EOF) and composite analyses were deployed in this study, where the global precipitation climatology center (GPCC) rainfall data is used. The SPI shows large widespread decreasing rainfall trend in the Sahel in the mid-1980s; thereafter, Sahel rainfall have recovered somewhat through the late 1990s, even though the drought conditions have not ended in the region. A ...
Projection of Future Streamflow Changes in the Pearl River Basin
Global climate change is remarkably changing the climatic patterns of the Pearl River basin and are significantly impacting the hydrological processes. Projection of future climate change impacts on steamflow variation is potential to provide scientific guidelines for sustainable water resources management and effective prevention and control for flood and drought disasters. In this study, a hydrological modeling system for assessing climate change impacts on runoffin the Pearl River basin was established and were used to simulate historical hydrological process and to project future streamflo ...
