側風偏流 的英文怎麼說
中文拼音 [zhāifēngpiānliú]
側風偏流
英文
cross wind drift-
The results show that there are two centers of occurrence of llsw respectively in dong bei and jiang nan ; the regional torrential rain over the yangtze river basin is closely associated with llsw during the major periods of heavy rainfall ; the diurnal variation of the number of occurrence in the middle and low reaches of the yangtze river is the strongest in china there are some significant differences between llj and nallsw in positive season, spatial variation, diurnal variation and field of pressure. by the way, the important effect of inertial stability on heavy rainfall with both low level south - westerly jet and high level northerly strong flow is analyzed theoretically. the results show that the existence of the maximum of inertial stability in the left font of the low level jet is favor of the accumulation of the moist thermal energy, and conditional symmetric instability or convective instability can be expected in this region
另外，慣性穩定性的作用以往不受重視，本文通過對西南低空急流左前方和高空偏北大風軸右後方的慣性穩定性和對稱穩定性的理論分析和實例計算，表明慣性穩定性在伴有高低空急流的暴雨中有重要意義，揭示了梅雨暴雨的一種新的高低空急流耦合機制：低空急流左前方慣性穩定度大值區的存在，有利於低層濕熱能量的積累，使低層傾斜對流的不穩定發展更多期望于條件性對稱不穩定或對流不穩定；高空偏北大風軸（西風急流）的存在，是其右後方（右側）出現對稱不穩定的有利條件，高空相對容易出現干對稱不穩定；慣性穩定性的作用，使低層的傾斜對流更偏向於垂直方向，有利於對流發展，使高層的傾斜對流更偏向於水平方向，有利於高層輻散。The flow propagates northward and marches across the equation, then passes through the trough of summer monsoon over south china sea and finally gets to the yangtze river valley, which sequentially effect the southwest airflow of the west side of subtropical high
（ 3 ）在副高西伸過程中，南半球澳大利亞高壓北側的冷空氣向北推進，經向風擾動持續向北傳播，從而影響副高西側的偏南氣流。Firstly, subtropical high center lay to the north than usual, and forms a blocking high in combination with land high in eastern asia. secondly, on account of the strong southwest current which occurred at the west side of the subtropical high and dynamic effect of the typhoon itself, the landing northward tropical cyclone ( 9711 ) landed in liaoning again. thirdly, a trough with some weak air from ural mountain and the northeast cold air entering into the tropical cyclone showed that the systems in different latitudes had some effects each other
模擬結果表明：此次熱帶風暴造成遼寧全省大暴雨的天氣背景是：副熱帶高壓偏北並與大陸高壓疊加，構成了穩定的東亞阻塞形勢； 9711臺風減弱的熱帶風暴，在其自身內力和副高西側的強盛偏南氣流引導下，持續北上並在遼寧營口至盤錦之間登陸；從烏拉爾山冷堆分裂南下出的弱冷空氣不斷南下，與熱帶風暴在遼寧產生了相互作用，增強了上升運動，致使大暴雨出現。In the droughts or floods over the yangtze river basin, between june and the second dekad in july, the moisture transport from the southern boundary, originating from south china sea and south china, is the most important influence factor, but between the last dekad in july and august, the one flowing out from northern boundary is the most important influence factor
長江流域旱澇年， 6 - 7月中旬來源於南海、華南地區的南邊界水汽輸入是主要影響因子， 7月下旬一8月北邊界的水汽輸出是主要影響因子。長江流域旱（澇）年夏季風水汽輸送的北界偏北（南） ，副高南側的東南風水汽輸送偏北（南） 。分享友人
