The change of meridional temperature gradient influences the strength of the meanmeridionalcirculation and the westerly jets directly.
经向温度梯度的改变，直接影响到对平均经圈环流及西风急流强度的模拟。

In the steady four-waves flow, the meanmeridionalcirculation is indirect, with a descending motion near the cold source and an ascending motion near the heat source, as shown in Fig.
维持四波时，平均经圈环流为靠近热源处下沉和靠近冷源处上升的反环流。

The meanmeridional and zonal-vertical circulation in Pacific region have beenanalyzed by using 1965—1973 monthly mean satellite cloudiness.
