Abstract: | The tropical heating and transient activity features during the period of the persistent anomaly of summertime circulation
over the Ural Mountains are studied, and a possible mechanism responsible for formation and maintenance of persistent anomalies
is proposed. The mechanism can be summarized as a kind of self-sustaining through a two-way interaction of stationary wave
with transient eddies under the consistent forcing of abnormal heating in the tropics. |
