Abstract:
By means of the precipitation data from 34 stations in Zhejiang Province and NCEP/NCAR monthly mean reanalysis data from March to May of 1960 to 2009, the climate characteristics of spring precipitation and the horizontal transportation in the whole atmospheric, the vertical transportation at various levels in the troposphere, and the regional crossboundary transportation of water vapor over Zhejiang Province are investigated, using the methods of trend analysis and correlation analysis and comprehensive analysis. The primary transporting paths and the areas related to vertical transportation of water vapor, as well as the circulation patterns influencing the spring precipitation, are expatiated. It is found that water vapor transportation fluxes through different boundaries have different contributions to spring precipitation in Zhejiang Province.
