Distribution Characteristics Of Tropical Cyclone’s Average Precipitation In Ningbo

This paper analyses 62 tropical cyclone which bring some precipitation to Ningbo.These 62 samples of tropical cyclone are classified into 5 catogories by their moving path which are type ofⅠ,Ⅱ,Ⅲ,Ⅳ,Ⅴrespectively.These samples bring to Ningbo different precipitation respectively whose space distribution is also different in Ningbo’s different area,which is researched elaberatively;There are two major thoughts to finish this research,first one,to develop a software to research single type of tropical cyclone which bring precipitation into Ningbo,the second,using a statistical method to research multiple types which bring precipitation into Ningbo as well.The first research method concludes some regularity between the location of cyclonic centers related with the location of Ningbo influenced by each tropical cyclone and demonstrate that the characteristic of path is the most important factor that brings precipitation into Ningbo while the rank of tropical cyclone is not.The second method concludes that the third type tropical cyclone name type III has the least influence on Ningbo whose precipitation has little spatial distribution.The tropical cyclone of type IV has the most influence on Ningbo whose precipitation has widely spatial distribution.Each other tropical cyclone has its own characteristic of spatial distribution of precipitation.Based on histrionic data,there’s two view of expectation,the first is to do query analysis and the second is to predict the future of tropical cyclone’s precipitation and its spatial distribution.
