摘要
本文将Cho的云模式引进大尺度位涡方程,利用FGGEⅢ_b资料计算了ITCZ区域的位涡源汇,并分析了它的分布情况。结果表明,Cho的云模式能较好地描述积云对流造成的位涡垂直输送。
Chao's cloud model is introduced into the large scale potential vorticity equation in this paper. The apparent potential vorticity source in the ITCZ area is calculated by using FGGEⅢ_b data and its distribution analysed. Results show that Chao's model can well represent the vertical transport of potential vorticity due to cumulus convection.
