cyclone center 中文意思是什麼
cyclone center
解釋
氣旋中心-
Through analysis of potential vorticity in equity - entropy surface field, a relatively high potential vorticity center in cyclone top in low - troposphere have discovered, and make cyclone develop in a more deep cyclone circulation by this ; and an anticyclone circulation zone with more severe low potential vorticity in high - troposphere
通過對等熵面的位渦分析，發現了對流層中低層的位渦場，在氣旋上方有一個相對高位渦中心，由此使得氣旋在一個比較深厚的氣旋性環流中發展；而對流層高層則是一個伴有較強位渦低值的反氣旋環流區。 -

從一九四七年至一九九九年，北太平洋西部及南海區域的熱帶氣旋非正式地採用美國軍方聯合臺風警報中心所編訂的名單上的名字。 -
Over the western north pacific and the south china sea between 1947 and 1999, tropical cyclone names were assigned by the u. s. armed forces joint typhoon warning center according to a pre - determined but unofficial list
從一九四七年至一九九九年，北太平洋西部及南海區域的熱帶氣旋非正式地採用美國軍方聯合臺風警報中心所編訂的名單上的名字。 -
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。 -
" residents of onslow are warned that very destructive winds will soon resume without warning from a different direction, " australia ' s bureau of meteorology said in its latest cyclone warning " very destructive gusts to 235 kmh are expected near the cyclone center, and are occurring on the coast in the vicinity of onslow, " it said
當地搶險部門預計，此次熱帶氣旋帶來的危害有可能接近10天前橫掃澳大利亞東北部的氣旋「拉里」以及去年8月給美國新奧爾良地區帶來重大損失的「卡特里娜」颶風。 -

Generally under 300hpa the subsidence zone of the potential vorticity lies above cyclone at the violent stage of the development of the cyclone, however, the center of cyclone still lies near the potential vorticity of large value above 300hpa
氣旋強烈發展期，一般300hpa以下，位渦的下沉區在氣旋的上空， 300hpa以上氣旋中心仍位於大值位渦後部。 -
It contributes to the development of the cyclone when the center of the potential vorticity is behind the cyclone at initial stages of the development of the cyclone and there is a manifest inverted conical subsidence zone under the 200hpa, which lies in the rear of cyclone
氣旋的發展初期，位渦中心位於氣旋的後部， 200hpa以下有明顯的倒圓錐形下沉區，該下沉區位於氣旋的後部。這種形勢有利於氣旋上空的位渦增長。 -
The article point out that the downward transport of the high moist potential vorticity from high level causes the development of low level cyclone. the rainfall may occur near the south area of positive center of mpv1 and negative region of mpv2 at 500hpa
在整個降水過程中，副熱帶高壓穩定少動，其西北側的暖濕氣流為強降水提供了充沛的水汽條件，地面冷鋒和高原低渦是其抬升機制。 -
The action that weak cold air penetrated into the tropical cyclone made the low pressure become vortex potential instability, and finally turned into kinetic energy. the results were that the center pressure of low became lower, the wind velocity around the cyclone was stronger and the precipitation became more
冷空氣在中低層的滲透主要使大氣斜壓作用加強，使不穩定能量的積聚並最終釋放；還造成臺風渦旋位勢不穩定，使熱帶氣旋中心氣壓降低，周圍風力加大，因而產生更大的降水。
