解釋
陽螺旋-
The positive storm - relative helicity center is accompany with low - level jet in 850 - hpa isobaric surface fields
通過分析我們發現了正的相對螺旋度中心與850hpa低空急流的演變過程是一致的。 -
The change of the positive stonn - relative helicity value has reflected the severe weak tendency of rainstorm and its system approximately
相對螺旋度值的變化大致反映了暴雨及其系統的強弱趨勢。 -
Severe cumulus precipitation of 3h center appear in the left side of positive stonn - relative helicity center, i. e. positive storm - relative helicity center is not synchronization with cumulus precipitation center of 3h, the cumulus precipitation center of 3h falls behind the positive storm - relative helicity center
在正的相對螺旋度中心的左側, 3小時后出現3h積雲降水量的高值中心,也就是說正的相對螺旋度中心和3h積雲降水中心不同步, 3h積雲降水中心落後于相對螺旋度中心。
