项目摘要

Subsaharan Africa has experienced measurable climate change over recent decades, with severe effects on local water resources, agriculture and health. However, our predictive methods for this region are unreliable, due to a lack of observations and a poor understanding of the processes controlling the West African Monsoon (WAM). As part of the international AMMA programme the UK will undertake a substantial effort, involving 8 institutions and more than 30 scientists, to measure the physical and chemical processes which determine the local climate and its global impacts. AMMA-UK will install an array of ground-based stations, between the tropical forest of the Guinea coast and the Sahara desert, to monitor climate over a two-year period. Within the vegetation canopy, measurements will be made of the environmental quantities which determine disease propagation and these will be related to the larger-scale weather and climate as derived from satellite observations. In the summer of 2006, an intensive campaign of aircraft and balloon-borne measurements will be used to analyse the atmospheric state and composition. Using a synthesis of the full set of measurements, the interaction of patterns of soil moisture and vegetation with weather systems and atmospheric composition will be determined. A co-ordinated programme of modelling will describe the role of the WAM in the global climate, improve our understanding of droughts and contribute to improved forecasts.

近几十年来，非洲的亚susharan非洲经历了可衡量的气候变化，对当地水资源，农业和健康产生了严重影响。但是，由于缺乏观察结果以及对控制西非季风（WAM）的过程的不良理解，我们对该地区的预测方法是不可靠的。作为国际AMMA计划的一部分，英国将付出巨大的努力，涉及8个机构和30多个科学家，以衡量决定当地气候及其全球影响的物理和化学过程。 Amma-uk将在几内亚海岸和撒哈拉沙漠的热带森林之间安装一系列地面站，以监视两年的气候。在植被冠层内，将测量确定疾病传播的环境量，这些测量与卫星观测得出的较大规模的天气和气候有关。在2006年夏天，将使用激烈的飞机和气球传播测量活动来分析大气状态和构图。使用整个测量值的合成，将确定土壤水分和植被与天气系统和大气成分的相互作用。建模的协调计划将描述WAM在全球气候中的作用，提高我们对干旱的理解并有助于改善预测。
