通過對等熵面的位渦分析,發現了對流層中低層的位渦場,在氣旋上方有一個相對高位渦中心,由此使得氣旋在一個比較深厚的氣旋性環流中發展;而對流層高層則是一個伴有較強位渦低值的反氣旋環流區。The analysis of dry pv shows that the high pv dominate the area of typhoon, the higher is the center value of pv, the stronger is the typhoon. lt is also shown that the most important reason resulting in rainstorm is the cold air ( high pv ) which spreads to south from the upper troposphere or lower stratosphere and transports into the warm air. the joining situation of upper and lower pv area make vortex develop. pv transpotation reduces static stability, which increases the releasing of instability energy and makes rainstorm amplify
對干位渦的分析表明:臺風或臺風環流區為高值位渦區,臺風越強,位渦中心值越大;對流層上部或平流層下部冷空氣(高位渦)的擴散南下與暖濕氣流的交匯是造成特大暴雨的重要原因,因為上游斜壓性的發展使對流層頂發生折疊,平流層與對流層相互作用增強,上下位渦區相接的形勢使低層渦旋發展,上升運動加強,位渦的下傳有效地降低了靜力穩定度,有利於位勢不穩定能量的釋放,使得暴雨增幅。The numerical simulation with complete forcing produces the main characteristics of yellow and east china seas circulation in summer. baroclinic effect plays a important role on yellow seas circulation that yellow seas cold water mass induces a anticlockwise circulation. tide also strengthens it
