warm vortex 中文意思是什麼
warm vortex
解釋
暖渦-
The magnitude of these variables increased approximately ten times. it helped the rapid releasing of instability energy. the interaction of high - level and low - level mesoscale system leads to the rainstorm. the vertical cross section analysis of potential temperature tells us that rainstorm take place in the warm - moist and instability area. usually locate in the very stiff moist isentropes and it can lead to the development of vortex
通過對相當位溫的垂直剖面分析，可知兩場暴雨的中低層都為暖濕不穩定區，暖濕不穩定區上部冷空氣明顯擴散，暴雨產生在暖濕對流不穩定區內，通常產生在_ e陡峭和密集區中， _ e陡峭和密集區有利於渦旋發展。 -
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。 -
But when the baroclinicity of low level vortex was strengthened and when warm air came into being, all the rain belts lay in the left and the front of southeast low level jet
當低渦的斜壓性加大，出現暖空氣的作用時，暴雨區均出現于西南風急流的左前方。 -
Especially, t - test shows that significance of the asia polar vortex, zonal circulation index, the most northern extension edge of subtropical high of northern west pacific and the warm pool of pacific ocean, are at 95 % （ 90 % ）
特別地，亞洲極渦、緯向環流指數、西太平洋副熱帶高壓北界位置及太平洋暖池的海表面溫度等因子均通過了95 % （ 90 % ）信度水平檢驗。
