摘要
利用巴彦淖尔市1961～2010年气温序列资料,采用气候倾向率和累计距平气候统计方法,分析各年、季和月平均气温以及平均最高、最低气温变化特征.结果表明,近50年巴彦淖尔市年和季平均气温均呈上升趋势;各月气温呈显著增温趋势,增温幅度为0.20～1.04℃/10a;平均最高、最低气温均呈上升趋势,线性拟合的变化倾向率分别为0.339和0.758℃/10a;近50年来共出现严重的冷冬13次(其中异常6次)、暖冬2次(其中异常1次),严重/异常冷冬多出现在20世纪60、70年代,严重暖冬均出现在21世纪.
Abstract
Based on the temperature sequence data in Bayannaoer City in recent 50 years from 1961 to 2010, we adopted the climate tendency rate and accumulative anomaly climate statistics method, analyzed the annual, seasonal and monthly average temperature, and researched the change characteristics of average maximum and minimum temperature.Results showed that the annual and seasonal average temperature were on the rise;monthly temperature enhanced significantly with the amplitude of 0.20-1.04 ℃/10a.The average maximum and minimum temperature showed an increasing trend.Their change tendency rates of linear fitting were 0.339 and 0.758 ℃/10a, respectively.In the recent 50 years,there were 13 severe cold winters (six abnormities) and two warm winters (one abnormity).Severe/abnormal cold winters usually appeared in the 1960s and 1970s;while severe warm winters usually appeared in the 21st century.
