| 摘 要： | 采用车载气象观测仪器结合GPS定位、连续数据采集系统的流动观测方法研究了北京城区内不同城市地表覆盖物对城市局地小气候的影响和气象要素分布,发现城市下垫面分布与城市的温度和湿度有密切关系,一般在城市建筑物密集、水体和植被少的区域具有较高的气温和较低的相对湿度,在建筑物稀疏和植被、水体较多的区域则相反。观测结果表明,流动观测方法是对常规气象观测资料的有益补充,也是城市气候观测中的一种有效方法。

| Abstract: | Combining GPS(Global Position System) and the data logger system,mobile measurements were carried out under clear weather and light wind conditions to research the urban heat island effect in Beijing.The impacts of different surface covers on urban local climate and the distribution of meteorological elements are investigated.The results show that the urban building-concentrated areas with less water and less vegetation have higher air temperature and lower relative humidity compared with the rural area.The mobile measurements are a useful supplement to conventional observation,and the mobile measuring approach is an effective method for urban climatic observation. |
