THE EAST ASIA/PACIFIC PATTERN TELECONNECTION OF SUMMER CIRCULATION AND CLIMATE ANOMALY IN EAST ASIA

In this paper,many observations show that the thermal states including the SST,the convective activities in the western Pacific warm pool largely influence the interannual and intraseasonal variations of summer circulation and the climate anomalies in East Asia.Moreover,it is pointed out that there is a teleconnection pattern of summer circulation anomalies in the Northern Hemisphere,the so-called East Asia/Pacific pattern.The cause of the teleconnection pattern is studied by using the theory of quasi-stationary planetary wave propagation,and it may be due to the propagation of quasi-stationary planetary waves forced by heat source around the Philippines.Moreover,this pattern is well simulated by using a quasi-geostrophic,linear,spherical model and the IAP-GCM,respectively.
