| Abstract: | By using NCEP reanalysis data and composition analysis and dynamical diagnosis,this paper compares the difference of the atmospheric circulation features about the typical Meiyu patterns of southern flood(drought) and northern drought(flood),and investigate the performance of dynamic identification of nearly 20 kinds of physical quantities for the main rain belt.The results show that: for the typical Meiyu pattern of southern flood(drought) and northern drought(flood) the polar vortex is stronger(weaker),th... |
