涡度中心 meaning in English
vorticity center
Examples
- 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
在这一区域内有一对最小气压中心，一个与最大涡度中心相重合，另一个则在更向北3公里左右处。 - By mesoanalysis of a precipitation that occurred in the middle reaches of the changjiang river , 8th jul . in 2003 , the formation and development of the event , its relation with the meso - microscale system are studied , it is emphasized that the low - level jet would cause favorable thermodynamic , moisture and dynamic conditions for the heavy rainfall in the middle reaches of the changjiang river and that the mesoscale vortex formed in the left of the low - level jet would stimulate strong convective clouds and cause the heavy rain
摘要通过对2003年7月8日发生在长江中游的一场大暴雨进行中尺度分析，初步研究了暴雨的形成及发展过程，总结了暴雨的产生与中小尺度系统的关系，着重阐述了低空急流在暴雨形成中的作用，以及在低空急流左侧强正涡度中心附近形成中尺度涡旋，激发暴雨云团等。 - The analysis for the evolution of the upper westerly field , north - south wind field show that the upper jet stream is a good indication to sandstorm - occurring areas , the strong sandstorm appears at the right side of the entry domain of the jet stream and the ascension domain of secondary circulation
对高空东西风场、南北风场的演变进行分析，发现高空急流对沙尘暴发生区有很好的指示作用，强沙尘暴位于200hpa高空急流入口区右侧、 500hpa正涡度中心下风方和次级反环流的上升区域内。
