【摘要】 搞要:选取化德地区1953-2005年的气温资料,对化德地区52年来的气温变化趋势进行统计分析,结果表明:52年来化德地区年平均气温变化率为0.72℃/10a。平均气温、平均最高气温、平均最低气温总体呈上升趋势,从气温的各要素变化特征可看出有3个特点:(1)最低气温的变化幅度高于最高气温的变化幅度;(2)冬季气温升高趋势最大。夏季增幅不明显,(3)平均最高气温、平均最低气温的变化具有明显的季节性特点。更多还原

【Abstract】 Selected temperature and precipitation in Huade during 1953～2005,have analyzed temperature variation tendency past 52years with standard deviation,variation ratio of linear tendency,graph and sliding parity.The results show:1.Variation ratio of annual mean temperature in Huade was 0.72℃/10a.Mean temperature,mean maximum temperature and minimum temperature had an increased tendency,and temperature elements fluctuated distinctly during the 50s ～ 80s;Temperature increased distinctly from 90s,there were three aspects:(1) The fluctuating amplitude of minimum temperature was greater than maximum temperature.(2) Winter temperature increased distinctly and have appeared 17 warm winter;(3) The variation of mean maximum and minimum temperature had an obvious seasonal characteristic;2.Annual precipitation presented fluctuant,tardo decreasing tendency and annual precipitation decreasing amplitude was less 39.0 mm than past 30 years.更多还原
