Techniques involved in developing the Australian Climate Observations Reference Network - Surface Air Temperature (ACORN-SAT) dataset
The Australian Climate Observations Reference Network – Surface Air Temperature (ACORNSAT) data set is a long-term data set of Australian daily air temperature, covering the period from 1910 to the present. The purpose of this data set is to provide the best possible data set to underlie analyses of variability and change of temperature in Australia, including both analyses of annual and seasonal mean temperatures, and of extremes of temperature and other information derived from daily temperatures. A full discussion of the motivation underlying the ACORN-SAT data set is contained in a compani ...Preparing Hydro-climate Inputs for Climate Change in Water Resource Planning
This lesson describes the process of selecting the best available climate projection information and using it to develop “climate-adjusted weather” inputs to be used for modeling climate change impacts. These modeled impacts can be used for planning of future water resources. Specific steps of this process include: 1) Recognizing the general science and terms associated with Atmosphere-ocean General Circulation Models (AOGCMs); 2) Making AOGCMs more regionally applicable through bias correction and downscaling; 3) Determining climate change scenarios based on climate projections and selecting ...Introduction to Climate Models
This module explains how climate models work. Because the modeling of both weather and climate share many similarities, the content throughout this module draws frequent comparisons and highlights the differences. We explain not only how, but why climate models differ from weather models. To do so, we explore the difference between weather and climate, then show how models are built to simulate climate and generate the statistics that describe it. We conclude with a discussion of models are tuned and tested.
Assessment and modelling of climate variability and change in Cameroon (central Africa)
Cameroon is located on the west coast of central Africa. It is home to about twenty millions inhabitants relying upon rain‐fed agriculture for food security. With the increasing pressure of climate change, other activities for sustainable development such as transport, energy, water, livestock and urban settlement are also facing an increasing threat due to extreme climate and weather events. In some cases today’s climate extremes are expected to become tomorrow’s ‘normal’ weather. This assumption stresses the need of understanding the past, the current and hopefully to project local climate b ...
Projection of crop yield in Bhutan under climate change using PRECIS regional climate model
Bhutan is classified as one of the forty-eight least developed countries with farmers comprising more than two-thirds of its total population. The agriculture sector, which is a significant contributor to the country’s gross domestic product, has been vulnerable to extreme climate events in recent decades. As an effort to address the potential challenges it will face under climate change, this thesis projects the yields of three primary crops grown in Bhutan, rice, wheat and maize, for the period 2030 to 2050, based on climate projections by the PRECIS regional climate model.

This study compares the properties of atmospheric dust from the Saharan deserts and the Asian deserts using data from CALIPSO and AERONET during 2006 and 2007 along with simulations using a coupled climate-microphysical sectional model. Saharan deserts are largely south of 30° N, while Asian ones are primarily north of 30° N, hence they experience different meteorological regimes. Saharan dust lifting occurs all year long, primarily due to subtropical weather systems. However, Asian dust is lifted mostly in spring when mid-latitude frontal systems lead to high winds. Rainfall is more abundant ...
Intercomparison of Models - Verification of Moderate Rainfall over Nigeria in the Summer of 2010
The science of weather forecasting is only as good as its ability to produce results. Models are some of the tools meteorologists have come to depend on to help them in forecasting and the dependability as well as reliability of a model is measured by its ability to track and forecast ahead of time a given event. Thus this study looked at the inter comparison of four models namely; GFS, ECMWF, UKMET and METEOFRANCE models, three of which are mostly used by the forecast offices of the Nigerian Meteorological Agency.How trees and people can co-adapt to climate change : reducing vulnerability in multifunctional landscapes
In this section we provide a more in-depth look at the role trees play in the provision of goods and services in multifunctional landscapes. Tree growth is, however, vulnerable to climate variability, depending on the physiological properties of the tree and characteristics of the site. A further quantification of climate variability and climate change is needed to advise on what types of trees can be grown where, to be ready for the likely local climate-change during their lifetime. This leads to a discussion of the two-way relationship between climate change adaptation and rewards for enviro ...Comparisons of Low-Level Circulation Characteristics between ECHAM5/MPI-OM Results and NCEP/NCAR Re-Analysis Data in East Asia
Atmospheric and Oceanic Science Letters, Volume 3 Number 4. Zhao De-Ming; Fu Cong-Bin - Science Press, 2010Regional climate models (RCMs) can provide far more precise information than general circulation models (GCMs). However, RCMs depend on GCM results for re-analysis products providing boundary conditions, especially for future climate scenarios. Meanwhile, the capacity of RCMs to reproduce precipitation is strongly connected to its performance on circulation and moisture transport simulations in the low troposphere, which is the key problem with RCMs at present. In the Regional Climate Model Inter-comparison Project for East Asia (RMIP III), the results of ECHAM5/MPI-OM (the European Centre-Ham ...Diapycnal Mixing in Transient Responses of the Atlantic Meridional Overturning Circulation in an Enhanced Freshwater Perturbation Experiment
Atmospheric and Oceanic Science Letters, Volume 3 Number 4. Yu Lei; Gao Yong-Qi; Helge Drange; et al. - Science Press, 2010It has been reported recently that the simulated Atlantic meridional overturning circulation (AMOC) using the coupled Bergen climate model (BCM) showed initial intensity declines followed by gradual recoveries over a 150-year enhanced freshwater input experiment. Stratification-dependent oceanic diapycnal mixing has been hypothesized as a reason for the simulated recovery of the AMOC. This study investigated the role of diapycnal mixing in transient responses of simulated AMOCs. Our results showed that stratification-dependent diapycnal mixing can cause stronger upwelling of deep water in the ...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.
