Of Enso Events On The Chinese Climate Impact Studies

ENSO events contribute to slgnlflcantweather changes around the world．The impact of ENSO events onChlna are mainly showed in rainfall In summer,typhoon actlvltles and lower ie叩erature ofNortheast China．But the seasonal叩act ofENS0events onChina is less Indicated． In this paper,the relationships between ENSO events and seasonal rainfall,seasonal temperature In China based on the long time series data of 36 stations from 1915 to 1998 are Investigated using X' methods．The results show that the impact ofENSO events onChlnahas distinguishing feature with different season and region． This paper Includes fourparts．In the first part,the achievement of study between ENSO events and climate around the world,especially In China are introduced．In the second part,re shoo the concept and SCale,frequoncy and forecast of ENso eVen土s,as well as土ho canS0s of It．In the third part,we analyses the relationship between ENSO events and seasonal climate In China．And then ne show the conclusion In the last part． The relationshipbetween ENS0events andralnfall,temPerature are more closely related In summer and autumn,Especially In northern area of East China and central section of East China．In EI Nlno years,the temperature over northern area of East China will Increase and the rainfall will decrease In summer and autumn．The ie仰erature over southern area of East China will increase and the rainfall will increase In summer and autumn．It may be the reason that monsoon In East Asia Is weaken and the subtropical high In west Pacific ocean moves to the south at that time．But in LaNinayears,the temperature and the rainfall will change adversely．There are no confident connect between ENSO events andralnfall,temperature In springandwlnter．The temperature going up around the earthmaybe the reason．So the impacts ofENSO events are more important factors toChlnese climates．...
