Abstract：By using the data of single weather station in Yichun from 2005 to 2012,40 samples of short-time strong precipitation are statistical analyzed in every 5 minutes.That the concept of exceed short-time strong precipitation with 10 minutes amount of precipitation≥10mm is summarized.Exceed short-time strong precipitation with 10 minutes amount of precipitation≥10 mm not only hold on to the highest frequency of occurrence in the past eight years,but also occur in short-time strong precipitation with 1 hour amount of precipitation≥30mm and 2 hours amount of precipitation≥50 mm.When short-time strong precipitation began,there are some obvious changes of air pressure rising,air temperature dropping,humidityascending,rainfall suddenly going up and leading wind increasing.It appears increasing trend of short-time strong precipitation year after year in Yichun weather station.Occurrence time of precipitation is central from April to Augustevery year and during the two periods of 4:00-5:00 BT and 14:00-20:00 BT every day.
