Abstract ATM-9807068 Eltahir, Elfatih Massachusetts Institute of Technology Title: The Role of the Distribution of SST and Vegetation in Rainfall Variability Over West Africa The request of $342,383/36 months is to examine the hypothesis that the rainfall variability over West Africa is regulated by the meridional gradient of boundary layer conditions (entropy or moist static energy). The influence of both vegetation distribution over land and SST variation over the tropical Atlantic ocean on the meridional gradient of the boundary layer will be examined. Both historical data and numerical models will be utilized for the study. The study is important since understanding monsoon variability over west Africa will help better predict droughts, floods; all this has high potential societal impacts.

摘要ATM-9807068 Eltahir，Elfatih马萨诸塞州理工学院题目：西非上空SST和植被分布在降雨变率中的作用 342，383美元/36个月的请求是为了检验西非降雨变化受边界层条件（熵或湿静态能量）经向梯度调节的假设。 陆地植被分布和热带大西洋海温变化对边界层纬向梯度的影响将被研究。 研究将利用历史数据和数值模型。 这项研究很重要，因为了解西非的季风变化将有助于更好地预测干旱，洪水;所有这些都具有很高的潜力 社会影响。
