涡场 meaning in English

eddy field
vortex field

The potential vorticity ( pv ) on isobaric and isentropic surface was studied . furthermore , the pv structure of another rainstorm caused by the 9711 typhoon was compared with it and the difference of the two rainstorm was discussed
另外又与1997年第11号台风登陆北上造成山东全省大到暴雨过程的位涡场结构进行了对比分析，讨论了两次暴雨过程位涡场结构的异同。
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
通过对等熵面的位涡分析，发现了对流层中低层的位涡场，在气旋上方有一个相对高位涡中心，由此使得气旋在一个比较深厚的气旋性环流中发展；而对流层高层则是一个伴有较强位涡低值的反气旋环流区。
