大暴雨发生在对流层中低层为气旋性涡旋、流场辐合加强、水汽通量增加、水汽通量辐合加强,并伴有高层较强辐散的情况下。
The heavy rain is presented under the condition of the strong positive vorticity, convergence, vapor flux convergence in middle and lower troposphere and stronger divergence at upper troposphere.
结果表明,瞬变的涡度通量辐合的异常有抵消辐散风所产生的涡度源异常的趋势;
The results show that the anomalies of transient vorticity flux convergences tend to cancel the anomaly of vorticity sources generated by divergent winds.
结果表明,瞬变的涡度通量辐合的异常有抵消或耗散辐散风产生的涡度源异常的趋势;
The results show that the anomaly of the transient vorticity flux convergence tends to cancel or dissipate the anomaly of the vorticity sources generated by divergent wind.
