A steady, shallow water atmospheric model is used to studythe influence of the ocean heating scale on the structure of Walker and Had1ey circulation in the tropical atmosphere. It is shown that whenthe heating scale is smaller than the critical scale, the results are similarto Gill’s (1980), that is,a hadley cell is located in the region of Rossby waves and an anti-Hadley cell in the area of Kelvin waves. When theheating scale is larger than the critical scale. a Hadley cell exists inthe entire heating region. In the latter case, a large scale Hadley cellcan transfer a great amount of heat and energy from the ocean to the extratropical region. This causes the atmospheric circulation there tobe anomalous. The results are consistent with statistical facts and sup-port the oretically the teleconnection which Bjerknes put forward inthe 1960s.
