摘要
本文首先给出一个乌拉尔阻塞定义,随后利用平均位涡方程和涡动位涡拟能方程,对一次Ω型冬季乌拉尔阻塞维持阶段作了分析,得出了一些有意义的结果。
A definition of the blocking over the Urals is given in thispaper. Some useful conclusions are drawn from the analysis of the persist-ence of the wintertime Ω blocking by use of the local time-averagedquasi-geostrophic potential vorticity equation and potential vorticityenstrophy equation.
