摘要： 本文利用1951-1989年近40年的气象资料,采用等级气温方法,对新疆冬春季气温异常时空变化和冬暖环流特征进行分析,结果表明:新疆冬、春季气温变化有明显的阶段性,主要表现为50年代偏冷;60年代前期偏暖;后期偏冷;70年代偏暖;近十年整个时期温度偏高.南疆的分布趋势和北疆近似,其振幅并不显著.

关键词: 等级温度, 气温异常, 环流特征, 新疆

Abstract: Meteorological data from 1950-1989 is used to analyse the anomalous air temperature change of time and space in winter and spring and the themal circulation characteristics in winter by grade air temperature method. The results suggest a obvious periodicity of air temperature change in winter and spring and mainly show that the temperature tend to be cold in 1950's，to be warm in early of 1960＇s，and to be warm in 1970's. Air temperature tended to be high during the last 10 years. The tendency pattern is similar in Southern and Northern region of Xinjiang but amplitude of Southern region is not remarkable.
