【摘要】 利用2010—2014年抚顺3个国家基本站的日最低、最高气温资料,以章党观测站为参考站,分别对清原和新宾2站日最高、最低气温进行差值统计分析,发现3站温差≥4℃总站次为212,温差大值主要体现在最低气温,且主要体现在章党站与新宾站的温差。最低气温温差大值多出现在1—5月、10—12月。按地面气压场进行天气学分型,发现导致3站最低气温温差大的天气形势可分为东高西低型、冷高压切入型、高压内部型和东部低压型。而3站日最高气温温差异常偏大的情况较少,且主要出现在夏、秋两季,往往是由于东部地区的降水导致。更多还原

【Abstract】 Based on the data of daily minimum temperature and daily maximum temperature from 3 national basic meteorological observing stations in Fushun from 1951 to 2003, the difference values of daily minimum temperature and daily maximum temperature between Qingyuan(Xinbin) station and Zhangdang station were analyzed. The results showed that the temperature difference greater than or equal to 4℃ of 3 observing stations was 212 stations. The temperature difference of daily minimum temperature between Xinbin station and Zhangdang station was big,and the large value of temperature difference mainly appeared from January to May and from October to December. The weather conditions leading to a large temperature difference of daily minimum temperature of 3 stations can be divided into east higher and west lower type, cold high pressure cutting in type, high pressure interior type and east low pressure type based on surface pressure field. The large value of daily maximum temperature difference mainly appeared in summer and autumn, which was cased by precipitation in east Fushun.更多还原
