中文拼音 [qìxuánnuǎnqū]
氣旋暖區
英文
warm sector of cyclone-
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 quasi - geostrophic process was diagnosed for a case of severe cold air breakout under the blocking situation during 16 - 18 march of 1998. the attention was focused on the relationship between the surface anticyclone and 500hpa blocking high. the results indicate that the cold outbreak is associated with the adjustment of blocking situation in the ural area, i. e. the collapsing and rebuilding of the ural mountain blocking high. the temperature advections in the lower troposphere shown that the polar cold air invading from the northwest caused the ural blocking high collapsed, and a new ridge developed rapidly was due to the warm advection on the southwestern side which led to the ural blocking high rebuilt. in addition, the distribution of the vertical motion on 700hpa shown that the surface high splitting was related to the considerable upward motion located on the southeastern part of surface high
對1998年3月中旬一次高空阻塞形勢下強冷空氣過程進行了診斷分析,著重討論強冷空氣爆發前後地面反氣旋活動與高空阻塞形勢調整的關系。研究結果表明,強冷空氣的爆發與烏拉爾地區阻塞形勢的調整阻塞高壓的崩潰和重建緊密相關。對流層下部的溫度平流分析表明,阻塞形勢的調整是由於阻塞高壓上游西北方有冷空氣侵入導致了阻塞高壓的崩潰,而上游來自西南方向的強暖流則導致高壓脊迅速發展,使阻塞高壓重新建立。Genetic analysis shows that it may be caused by the difference of the response of each area to winter monsoon ' s abnormal, the kuroshio and our offshore is influenced mostly by heat flux between the sea and atmosphere, but in the other areas, the abnormal current incited by abnormal wind has decisive effect on the change of the sea temperature, at the same time, air pressure also has some impact on the sea temperature
其區域性形成的原因主要可能是因為各海區對冬季風異常的響應方式不同,強冬季風使得黑潮與我國近海海洋過多散熱,海溫降低;在西北太平洋暖池北部,強冬季風引起西風異常,從而引發異常氣旋性環流,海水輻合下沉加熱其表層以下海水,同時異常環流使得更多東側異常暖水向西加熱其表層水;在黑潮與親潮交匯處的升溫也主要是由於強冬季風導致的流場異常,海水輻合下沉升溫。A warm water current within it swirls clockwise, affecting the weather of the area, keeping it calm and steamy
在它裏面暖流漩渦成順時針旋轉,影響了該區域的天氣,使藻海平靜和水汽彌漫。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。Still, the coastal areas of asia face future challenges : cyclones and their attendant surges will take an increasing toll as global warming disturbs weather systems
亞洲的沿海區域仍得面對未來的挑戰,當全球暖化的現象擾亂了氣候系統,氣旋和隨之而來的大浪會造成更大的損失。Results show that there are two main spatial patterns of the wp ssta : one is uniform in the whole area, the other is of the north - south asymmetry. when the spatial pattern is uniform in the whole area, in the warm years, there is a anticyclone circulation existing over the warm pool and westerly in the subtropical region and easterly in the tropical region have been greatly strengthened at 850hpa, while a anticyclone circulation over the india region at 200hpa, the walker circulation has been strengthened, the summer rainfall may be above normal in the upper and middle reaches of the yangtze river, vice versa
當ssta為一致性分佈時,暖異常年, 850hpa暖池區上空為一反氣旋偏差環流,副熱帶地區西風和低緯度地區東風得到加強,長江中上游地區盛行偏南風氣流; 200hpa南亞上空為一反氣旋偏差環流,長江中上游地區為北風; walker環流加強,副熱帶高壓偏強,經向垂直環流在25 35 n附近為上升氣流,長江中上游地區降水偏多,是lanina事件的多發年,對應的soi指數偏高,冷異常年則相反。分享友人
