Warm season diurnal precipitation over the plains east of the Rockies

点击翻译按钮获取中文摘要

The plains east of the Rockies are central to global grain production and known as the Breadbasket of the World. These regions are subjected to a high frequency of extreme rainstorms with summer flooding frequently associated with heavy precipitation generated by convective and synoptic weather systems. However the rainfall diurnal cycle especially the nighttime rainfall maximum observed over the plains is poorly understood. The eastward propagating of the convective systems is also largely under-represented in current numerical weather prediction models. Compared to the US Great Plains, the summertime diurnal precipitation over the Canadian Prairies is relatively unexplored.
