摘要:

基于2018—2021年哈尔滨气象骨干自动站网逐小时监测数据,分析城市对夏季降水的影响。结果表明:哈尔滨夏季热岛强度平均为0.79℃,日变化表现为夜间较强,白天较弱;东郊气温差最大,北郊最小;哈尔滨夏季偏下风方的东郊降水量最多,上风方的南郊最少。哈尔滨夏季逐小时降水概率郊区大于城区,郊区的较多降水时次相对城区表现为午后推延、清晨提前;降水概率城区日间大,郊区夜间大,北郊日夜差最大;小时最大降水量郊区大于城区,降水强度城区与东郊大于南郊和北郊。哈尔滨短历时降水更频繁,降水贡献率更大;6 h内历时降水城区最多,北郊最少;6~12 h历时降水城区最少,东郊最多;>12 h历时降水发生率北郊最大,降水贡献率南郊最高。

Abstract:

Based on the hourly monitoring data of the meteorological backbone automatic stations in Harbin from 2018 to 2021, this paper analyzed the impact of the city on summer precipitation.Results showed that: the heat island intensity in Harbin is 0.79℃ on average in summer with a daily variation that is stronger at night and weaker in daytime.The temperature difference is the largest in the eastern suburbs and the smallest in the northern suburbs.The most and least precipitation in summer is respectively distributed in the eastern suburbs on the downwind side and the southern suburbs on the upwind side in Harbin.The hourly precipitation probability is higher in suburbs than in urban areas, and many precipitations occurring in the afternoon and early morning for the former are respectively delayed and advanced relative to these for the latter.The precipitation probability is greater in urban areas during the daytime and in suburbs at night.The difference of precipitation between daytime and nightime in the northern suburbs is the largest.The maximum hourly precipitation in the suburbs is greater than that in the urban areas.The hourly precipitation intensity in the urban area and the eastern suburbs is larger than in the southern and northern suburbs.Short-duration rainfall in Harbin′s is more frequent and has a greater contribution rate.The precipitation lasting within 6 hours appears most frequently in urban areas, and rarely in the northern suburbs, and that lasting for 6-12 hours appears rarely in urban areas and most frequently in the eastern suburbs, while that beyond 12 hours occurs most frequently in the northern suburbs, and shows the highest contribution rate in the southern suburbs.
