Based on the NCEP 1°×1° reanalysis data and the precipitation data from AWS in Zhejiang Province,the relationship between precipitation resulting from distant typhoon(PDT) and the perturbation kinetic energy dispersion (PKED) of typhoon Krosa is analyzed.The results show that the mechanism of PDT in Zhejiang Province is different from that in north region of China because the PDT here is formed by the distant propagation of disturbance kinetic energy of typhoon while the PDT in north region of China results from the interaction between westerly trough and outer circulation of typhoon.The PKED of typhoon occurs both before and after its landfalling in Zhejiang Province.The intensity of disturbance kinetic energy is different at lower,middle,and upper levels in troposphere.The larger the amplitude of disturbance kinetic is,the longer of the wave propagation distance will be.The intensity of disturbance kinetic energy at middle and upper levels is larger than that at lower level in troposphere,so the PKED at middle and upper levels in troposphere can exert impact on the precipitation in Zhejiang Province when the typhoon location is far from it but that at lower level can not.The PKED from distant typhoon can produce a positive vorticity area at the upper level in precipitation region.And then the local cyclonic circulation comes into being because of the downward propagation of the positive vorticity from upper level.Finally,the combination of local cyclonic cell with the moisture flow from the east sea of China leads to the enhancement of local precipitation.
