Abstract：The first rainy season precipitation in South China is often characterized by heavy rainfall events lasting for more than 3 days,and even up to 10 days or more.These events,known as Persistent Heavy Rainfall Events(PHRE),result in severe flooding disasters in the region.Improving extended-range(10-30 days or 2-6 weeks in advance)precipitation forecast skill for the first rainy season is crucial.This paper focuses on the precipitation predictability sources of the first rainy season in South china,as well as the current application of numerical models,dynamical-statistical downscaling,and machine learning in the field of extended-range forecasting.The aim is to synthesize major advancements in extended-range precipitation forecasting for the first rainy season in South China.
