【摘要】 根据国内12个大中城市的12个气象站实际测量的2008年5月份31天的天气最低温度和最高温度共744个数据,结合曲线图对其特征进行对比研究,表明:①南宁市和广州市的低温,北京市和济南市的高温、低温,该月最低值都出现在5月12日汶川地震当天;②其他城市该月低温最低值出现的时间为:哈尔滨市9日,西宁市10日,西安市、郑州市、武汉市和呼和浩特市13日,都江堰市和绵阳市15日;③秦岭山—祁连山—昆仑山中央造山带地区的西宁市、西安市、郑州市和武汉市,华北地台构造区的北京市、济南市和呼和浩特市从5月6日到16日为温度负异常峰值区间;④温度降低幅度,按地理位置向北、向东减小。据此特征,结合现今青藏高原的应力场,讨论了青藏高原与汶川地震、地球物理场与大气物理场的关系,建议在研究强烈地震发生机制时应加强多学科的有机结合。更多还原

【Abstract】 Basing on the 744 data of the lowest and highest air temperature being measured in fact in May 2008 in 12 big and middle cities of China,researching the data and their curves,the results show as following: ① The low air temperature of Guangzhou and Nanning cities,the low and high air temperature of Beijing and Jinan cities,the lowest data in this month appeared on 12 May when Wenchuan earthquake occurred;② The lowest data in low air temperature appeared in other cities respectively as following: Ha’erbin is on 9,Xining is on 10,Xi’an,Zhengzhou,Wuhan and Hohhot are on 13,Dujiangyan and Mianyang are on 15 in May;③Xi’an,Xining,Wuhan and Zhengzhou are located Qinling-Qilian-Kunlun mountains and adjacent region,Beijing,Jinan and Hohhot are located in North of China plate region.In these 7 cities,subtractive anomalies detected from 6 to 16 in May;④ The scope of temperature fallen,according to geography position,reduced in northward and eastward.Thinking of the above characteristics and the stress field of Tibetan Plateau,the authors discuss the ralation of Tibetan Plateau and Wenchuan earthquake,geophysical field and atmospheric physics field,and suggest much more subjects should be integrated in studying earthquake formation mechanism.更多还原
