摘要： 基于西青地区2018—2022年街镇气象站逐时观测数据,对比分析了城市化对西青气象要素的影响。结果表明,城市化使得西青城镇气温高于乡村,冬季温差最大,在最低气温极值方面,城乡差异更为明显。日内气温差异在夜间更为显著,但最低气温差值仅在后半夜明显。降水城乡间无显著区别。风速上城镇弱于乡村,其中平均风速及其差异均在春季最大,大风极值城乡差异则在夏季更明显。城乡平均风速及极大风速均存在日变化,城乡差异在午间最为显著。

Abstract: Based on the hourly observation data of meteorological stations in Xiqing from 2018 to 2022,the impact of urbanization on the meteorological elements in Xiqing was compared and analyzed. The results show that urbanization makes the air temperature in urban areas higher than that in rural areas, with the largest temperature difference in winter. The extreme value of minimum temperature is more obvious between urban and rural areas. The difference of intra-day temperature is more significant at night,but the difference of minimum temperature is only significant at the second half of the night. There is no significant difference between urban and rural areas in precipitation. The wind speed in urban areas is weaker than that in rural areas,and the average wind speed and its difference are the largest in spring,while the difference of extreme wind speed is the largest in summer. The average wind speed and extreme wind speed in urban and rural areas have diurnal variation,and the wind speed difference at noon is the most obvious.

Key words: Xiqing, urbanization, air temperature, precipitation, wind speed
