近47年环青海湖地区气候变化特征分析
Analysis on the Characteristics of Climate Change in the Surrounding Area of Qinghai Lake in Recent 47 Years
摘要
Abstract
[ Objective] The aim was to study the characteristics of climate change in the surrounding area of Qinghai Lake. [ Method] Based on the data of temperature, precipitation and sunshine hours from 5 representative meteorological stations in the surrounding area of Qinghai Lake during 1961 -2007, the annual, seasonal and decadal variation of meteorological factors were analyzed. [ Result] In recent 47 years, temperature showed obvious increase trend in the surrounding area of Qinghai Lake, and annual average temperature increased with the climatic tendency of ≥0. 30 ℃/10 a, while there was more significant increase in annual average minimum temperature than annual average maximum temperature; annual mean precipitation decreased with the climatic of -3.67 mm/10 a, and precipitation in spring and autumn reduced obviously, while precipitation in summer and winter increased slightly; annual sunshine hours also showed decrease trend with the climatic tendency of -1. 79 h/10 a, while the decreasing trend of sunshine hours was most obviously in summer, and next came winter, while there was no obvious increase in spring and autumn. [ Conclusion] The study could provide theoretical references for the effective prevention of meteorological disasters in the surrounding area of Qinghai Lake关键词
