西安机场南北跑道气温对比分析

Contrastive Analysis of Temperatures at North and South Runways of Xi’an Airport

基于西安机场南北跑道逐小时气温资料,对两跑道温差的变化特征进行了对比分析。结果表明:南跑道平均气温高于北跑道;日变化来看,两者温差最大值出现在15时(UTC),温差为3.4℃;最小值出现在10时(UTC),温差为2℃。月变化来看,平均气温、最低气温月平均气温温差最大值均出现在12月,最高气温月平均气温温差最大值出现在7月;平均气温、最高气温、最低气温月平均气温温差最小值分别出现在9月、10月和7月。南北跑道逐时温差最大值集中分布在12月~次年1月,最小值集中分布在6~9月。

Based on the hourly temperature data of the south and north runways of Xi’an Airport, the characteristics of the temperature difference between the two runways are compared and analyzed. The results show that the average temperature of the south runway is higher than that of the north runway. From the perspective of daily changes, the maximum temperature difference between the two appears at 15 UTC, the temperature difference is 3.4?C, and the minimum appears at 10 UTC, the temperature difference is 2?C. In terms of monthly changes, the maximum temperature difference of the average temperature and the minimum temperature appears in December, and the maximum temperature difference of the maximum temperature appears in July. The minimum temperature difference of the monthly average temperature, the maximum monthly temperature, and the minimum monthly temperature appear in September, October, and July. The maximum hourly temperature difference between the north and south runways is concentrated from December to January, and the minimum value is concentrated from June to September.
