Abstract

　　During the winter season, northeast monsoon together with lifting of the air current caused by the mountain terrain brings a long period of rainy weather to the northern Taiwan. One of the main factors which cause the fine weather over northern Taiwan is the certain surface synoptic features. It is observed that there is a close relationship of the tracks of the polar continental high pressure system to the weather in Taipei area. This paper attempts to provide a more objective and quantitative method by which the fine weather in Taipei area could be predicted to a desirable degree of accuracy during the winter season.
　　By using the skill score to verify the results, it shows that the best relationship falls in the period from November to February, and the poorest in April.
　　The prediction of the continental migratory highs, which move to the east of 125°E. has preliminarily been studied.
