Multi-scale Analysis of African Easterly Waves

非洲东风波是天气尺度的天气系统，是北半球夏季西非季风和热带大西洋下游发展的特征。这些系统与热带非洲的日降雨量有着重要的联系，它们可以作为热带气旋穿越大西洋的先兆。该项目将研究非洲和热带大西洋上空非洲东风波的生命周期和动力，以及非洲东风波活动的季节性和年际变化的性质和原因。这个项目有三个研究生参与。

African easterly waves are synoptic-scale weather systems that characterize the West African monsoon and downstream tropical Atlantic developments during boreal summer. These systems have an important association with daily rainfall over tropical Africa, and they can serve as precursors for tropical cyclones that cross the Atlantic. In this project, the PI will study the lifecycle and dynamics of African easterly waves over Africa and the tropical Atlantic, and the nature and causes of intra-seasonal to inter-annual variability of African easterly wave-activity.The project involves the participation of three graduate-students.
