摘要
[Objective] The aim was to analyze the climatic characteristics of temperature in '24 solar terms' in Liaoning Province.[Method] Based on the daily temperature data from 56 stations in Liaoning Province from 1951 to 2009,the climatic characteristics of temperature in '24 solar terms' in Liaoning Province in recent 59 years were analyzed.[Result] The time series of average temperature in '24 solar terms' in Liaoning Province showed quasi normal distribution from 1951 to 2009,namely single peak type.Great Heat meant the hottest time within one year,and next came Slight Heat,while Slight Cold was the coldest time within one year,and Great Cold took the second place.Among 24 solar terms,temperature increased most obviously in Tomb-sweeping Day,with the increase of 4.9 ℃,while temperature decreased most greatly in the Beginning of Winter,with the decrease of 5.1 ℃.There was obvious decadal variation in average temperature in Slight Heat,Great Heat,Slight Cold,Great Cold and the End of Heat which were closely related to temperature,and average temperature went up with time.From 1951-1980 to 1981-2009,average temperature in 22 solar terms showed increase trend,and there was no change in one solar term,while average temperature in one solar term decreased slightly,and average temperature in 24 solar terms increased by 0.66 ℃.[Conclusion] The study could provide scientific reference for meteorological service.
