中国冬季气温的时空特征分析
Characteristics of Winter Temperature in China
摘要
Abstract
In order to find out the winter weather characteristics and offer the weather forecast, with the time variation and regional characteristics of average,maximum and minimum winter temperature were analyzed orthogonal function, rotated principal component analysis and Mann-Kendall method through homogenizing the daily average, maximum and minimum winter temperature data (1960-2009) based on 201 stations (without influence of homogenization as relocation of station) in China. Results showed that winter temperatures of average, maximum and minimum were unusually relatively cold and warm, of which trend was up on average in 50 years. The quadratic mean deviation of average, maximum and minimum winter temperatures (1960-2009) in north was more than in south. The trend of all three (average, maximum and minimum winter temperature) was up and trend of average and minimum temperature was remarkably upward in almost national parts and northern trend coefficient was larger than the southern.关键词
