The Study on the Objective Technique for Partitioning Tropical Cyclone Precipitation in China
An advanced technique for partitioning tropical cyclone precipitation is studied. First, indices describing the differences between the subjective and objective partitioning precipitation are defined. Second, an idea for generating developing scheme was drawn up: changing the two important fixed parameters into variable parameters. Finally, the best scheme for the advanced technique is determined.Results show that the advanced technique has made a great improvement. Then, case verifications, especially with NOAA’s CMORPH data, prove that the advanced technique showed relative strong ability in distinguishing precipitations from two different TCs or a TC with a mid-latitude system.
