| 摘 要： | 利用2017年晋江市及其周边共27个自动气象站逐小时气象资料,分析了2017年晋江城市热岛强度的日变化及有无海陆风对城市热岛强度的影响,同时研究了不同季节海陆风风速对城市热岛强度的影响,最后通过典型个例海陆风日验证了晋江城市热岛的日变化特征。结果表明:晋江市全年平均热岛强度的日变化趋势呈“V”字型分布;海风能使城市降温,减弱城市热岛强度,而陆风能使夜间热岛显著增强,故与非海陆风日相比,海陆风日热岛强度的日变化幅度增大;热岛强度与海陆风风速呈负相关,海陆风风速越大对城市热岛有一定的缓解作用。

| Abstract: | Based on the hourly meteorological data from 27 automatic meteorological stations in Jinjiang and its surrounding areas in 2017, the diurnal variation of urban heat island intensity in Jinjiang in 2017 and the influence of sea-land breeze on urban heat island intensity were analyzed. Moreover, the influence of sea-land breeze speed in different seasons on the urban heat island intensity was also studied. Finally, the diurnal variation characteristics of urban heat island in Jinjiang were verified by a typical day with sea-land breeze. The results show that the annual average heat island intensity in Jinjiang City has a V-shaped diurnal variation trend; the sea breeze cools the city, and weakens the urban heat island intensity,while the land breeze can significantly enhance the heat island at night. Thus, the durinal variation of the heat island intensity at the day with sea-land breeze increases, compared with the day without sea-land breeze. The heat island intensity is negatively correlated with the sea-land breeze speed. The faster sea-land breeze speed can alleviate the urban heat island to some extent. |
