For comparison,numerical simulations are conducted of influence on stationary waves of anomalous heat sources at high/low levels over the Tibetan plateau and western Pacific in terms of a 3D steady primitive equation spectral model.Results show that with low(high)level heating anomaly available in the highland,the maximal circulation anomaly centers shift to the anomaly centers for all levels whilst the high/low level heating anomalies over the western Pacific make the maximal circulation anomaly centers 10～20 deg of latitude northward of the heating anomalies.The high/low level heating anomalies under study have greatly differing effects on south Asian highs and western Pacific subtropical highs.
