With 1983～1988/1989 seasonally-averaged global heating data, the latitudinal and longitudinal uneven distribution characteristics of the heating anomaly with respect to 6 year mean in these years are analyzed. Based on the heating anomaly is alternate positive and negative anomaly meridionally and there are some main heating anomaly zonally. Numerical simulation is carried out of influence on circulation of latitudinal/longitudinal uneven anomalous heating in terms of a 3D steady primitive equation spectral model. Evidence suggests that the latitudinal uneven anomalous heating enhances obviously the meridianal circulation anomaly which is different from the linear superposition of circulation anomaly caused by those single anomalous heatings while the linear superposition effects of longitudinal uneven anomalous heating is relatively clear.
