东北地区极端气温事件时空分布特征研究

Temporal and Spatial Characteristics of Extreme Temperature Events in Northeast China

在全球气候变化的大环境下,气温变化对人类生产生活产生了重要的影响。东北地区是我国气候变化的重要区域,因此,对该地区的极端气温研究具有重要意义。研究利用1960—2014年东北地区99个气象站冬季(12月至次年2月)极端气温指数(暖日、冷日、暖夜、冷夜)资料,基于极端气温指数、空间插值方法和趋势分析法,研究了东北地区极端气温时间变化与空间分布特征。

In the environment of global climate change, the change of temperature has an important influence on human life. The northeast region is an important region of climate change in China, so it is of great significance to the study of extreme temperature in this area. Collect 1960 to 2014 Northeast 99 meteorological stations in winter (December-February), extreme temperature index (warm, cold days, warm nights,cold nights), based on extreme temperature index, spatial interpolation methods and trend analysis, the extreme temperatures of the Northeast time and spatial distribution.
