1961-2010年绥化市温度和降水变化特征分析

摘要

以绥化市测站数据为基础,同时选取气温和降水2个主要气象要素指标,采用线性倾向估计最小二乘法和滑动平均法对1961-2010年绥化市温度和降水的变化趋势进行探讨并统计年代际特征。结果表明：近50 a来,绥化市春季、秋季、冬季平均气温以及年平均气温均呈明显的增加趋势,夏季虽有增温趋势,但不显著。降水量呈波动变化并略有减少。%The data of temperature and precipitation from Suihua weather station was selected as the main factors,and the variation trend and the interdecadal change characteristics of these two factors from 1961 to 2010 was analyzed by the least square method and moving average method.The results showed that the average temperature of spring,autumn and winter in Suihua city increased clearly,also in the summer,but not clearly,the precipitation decreased slightly with fluctuation.
