| 摘 要： | 将本世纪以来我国137个站每个站逐月的月平均气温划分为五个等级,绘制了全国范围的历年逐月温度等级分布图。根据图中各月冷暖区范围大小,分为暖月、偏暖月、冷月、偏冷月和正常月五种类型。计算了全国范围和东北、华北、长江中下游、华南、西北(主要指陕西、甘肃、宁夏、青海等四省区。以下同)、西南和新疆等七个区的温度等级值。根据这些资料,统计分析了五类温度月份出现的气候特征及不同季节冷暖月次的多年变化,研究了全国和各区温度等级值的演变规律及其相互联系,以及近30年来我国气温演变的某些特征。

| Abstract: | The monthly mean temperature at 137 stations in China in present century are classified into five grades 1-5.Maps of grade distribution have been prepared for every month and year. According to the intensity of cold or warm areas, the monthly temperature grade distribution is classified into 5 types: cold (C), warm (W), sub-cold (Cw), sub-warm (Wc) and normal (N). For every month, mean grades are computed for seven regions: northeast China; north China; middle and lower Yangtze; south China; southwest China; northwest China;Xinjiang.Based on the above materials statistical anaysis of the occurences and secular variation of five types are made and associations among the regions are studied. The characteristics of temperature variation of last thirty years are discussed. These results are useful for understanding the climatic change in China and may serve as background for long-range forecasting. |
