vorticity center 中文意思是什麼
vorticity center
解釋
渦度中心-
The phenomena of initial disturbance vorticity translating into spiral bands is most evidently for it locating at the periphery of radius of maximum wind ( rmw ), near rmw next and the spiral bands vanish when it is positioned in the inner core region. indicating that the farther the distance from the tc center, the more distinctly the spiral bands and the opposite is true
初始圓形擾動渦度場轉化為螺旋臂渦量帶的現象是初始擾動位於渦旋最大風速半徑（ rmw ）外圍最顯著，其次是rmw附近，當擾動位於渦旋內核區時幾乎沒有螺旋臂結構形態出現，表明，初始擾動離tc中心越遠，其強迫渦旋rossby波形成的螺旋帶結構越明顯，反之越弱。 -
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。 -
Results show that typhoons had different characters of boundary layer temperature and vorticity fields at different life stages, and the intensity of typhoons was inversely proportional to the distance between warm center and maximum positive vorticity center, that is to say, the smaller the distance, the stronger the typhoon
結果表明：在臺風的不同發展階段，其大氣邊界層相對渦度場和溫度場的結構有著明顯的不同特徵，暖中心與正渦中心的距離與臺風強度為反相關關系，暖中心與正渦中心的距離越小，臺風強度越強。 -
Within this area is a double minimum in pressure with one center collocated with the vorticity maximum and the other about 3 km farther north
在這一區域內有一對最小氣壓中心，一個與最大渦度中心相重合，另一個則在更向北3公里左右處。 -
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。
