氣旋擴展 的英文怎麼說
中文拼音 [qìxuánkuòzhǎn]
氣旋擴展
英文
cyclone development-
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。Apart from the above weather stations, meteorologists from the three places also established over the years the exchange of real - time weather information through dedicated data lines, the networking of weather radar data from the area, and the closer consultation among forecasters in these places during the approach of severe weather. currently in progress is the expansion of swirls ( short - range warning of intense rainstorms in localised systems ), developed by the hong kong observatory, to a rainstorm forecasting system covering the pearl river estuary
除上述氣象站外，三方的氣象人員多年來還實現了利用專用數據線路交換實時氣象資料、將三地的天氣雷達數據聯網、以及加強了三方預報員進行重要天氣評估的磋商等。目前正開展工作，以香港天文臺開發的小渦旋暴雨臨近預報系統為基礎，致力擴展成一套覆蓋整個珠江三角洲的暴雨預報系統。
