摘  要:
利用气温距平、线性倾向、滑动平均及小波分析等方法,对鞍山市1951~2005年鞍山观测站的气温、降水量、平均最高气温、平均最低气温、透雨等资料进行分析,结果发现鞍山市近55a春季气候变化特点为气温、降水呈现上升,且春季降水存在19~20、5和3 a的主要变化周期、日照略减少的趋势;平均最低气温升温幅度高于平均最高气温,气温日较差变小;透雨偏晚及极端气候事件频率增大。

摘  要:
The data of air temperature,precipitation,mean highest and lowest temperatures,soaking rain etc.of Anshan city from Anshan observation station in 1951~2005 were analyzed by the methods such as air temperature anomaly,linear trend,moving average and wavelet analysis.It was found from the results that the climatic change characteristics of Anshan city in spring in recent 55 years were as follows: the air temperature and precipitation showed increasing trend and the spring precipitation had main change periods of 19~20,5 and 3 years with little decreasing trend of sunlight;The increment of mean lowest temperature was higher than that of mean highest temperature and the daily difference of air temperature reduced;The soaking rain inclined to be late and the frequency of extreme climate event increased.
