【摘要】 利用广东省沿海地带气象站、海洋站观测的1960—2003年气温资料,以5个无热岛效应影响的海岛站气温为参照,分析了近44年沿海18个气象站受城市热岛影响的程度,得出台山、珠海、汕尾、惠阳气象站的热岛影响可以忽略不计,其余14个站不同程度地受热岛影响。受热岛影响的气象站近10年平均热岛强度为0.4～0.8℃、近30～50年间年平均气温升温率较参照站增加0.1℃/10a～0.3℃/10a。更多还原

【Abstract】 By taking the data from five stations without heat-island effect as reference,the heat-island characteristics in the coastal cities of Guangdong Province were investigated based on the air temperatures data from meteorological and oceanographic stations nearby the coastal regions during 44 years between 1960 and 2003,and the impact characteristics of heat island on eighteen coastal meteorological stations were assessed respectively.The results indicate that,to a great degree,the fourteen meteorological stations are affected by heat-island,except four of the eighteen stations.Intensity of heat-island is from 0.4 to 0.8 ℃ over the past ten years with significant seasonal variations.Due to the heat island impact,the annual mean air-temperature is increased by 0.1℃/10a to 0.3℃/10a in the recent 30 to 50 years,in comparison with reference stations.更多还原
