暖心氣旋 的英文怎麼說
中文拼音 [nuǎnxīnqìxuán]
暖心氣旋
英文
warm-core cyclone-
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。When the spatial pattern is of the north - south asymmetry, in the warm north - cold south years, there is a anticyclone circulation existing over the warm pool at 850hpa, easterly at 15 n and westerly in the tropical region have been greatly strengthened, while the center of anticyclone circulation moves to the east asia at 200hpa, and the hadley circulation has been affected evidently, so the summer rainfall may be above normal in the middle and lower reaches of the yangtze river, vice versa. there are different relations to east asia atmospheric circulation and summer rainfall in china
當ssta為南北半球反對稱分佈時,與ssta北暖南冷分佈相對應, 850hpa暖池區上空為一反氣旋偏差環流, 15 n附近東風氣流和赤道附近西風氣流增強,長江中下游地區盛行偏南風氣流; 200hpa反氣旋偏差環流中心移到東亞大陸上空;副熱帶高壓強度、西伸脊點都明顯變強、西伸; hadley環流得到發展,長江中下游(華北)地區為上升(下沉)氣流,降水明顯增多(減少) ,北冷南暖年則相反。
