It is revealed that typhoon AERE making landfall Fujian province several times is mainly induced together by revolving each other between two typhoon, barring of high pressure and the strong Northern current beside landmass . By using observations from Doppler radar, the meso-scale spiral bands is studied and then the meso-scale characteristics of typhoon heavy rainfall is discovered. Analyzing the physics s...
