| 摘 要： | 利用2000年夏季南京志区地面气象要素和低层探空资料，分析了该夏季南京城区早、晚低层逆温的频率、厚度和强度变化特征，着重从统计角度研究了逆温的厚度、强度与城区地面温度、相对湿度变化的关系及对人体舒适状况的影响。结果表明：低层逆温对城区地面温湿变化及其幅度影响较大，当07时有逆温层时，08时至14时的温度增加幅度变大，相对温度减小幅度也变大，人体不适指数增加幅度变大；当19时有逆温层时，20时至23时温度减小幅度变小，相对湿度增加幅度也变小，人体不适指数减小幅度变小，并通过相关分析建立了人体舒适度指数与逆温强度之间的回归方程。

| Abstract: | Based on the ground-level meteorological data and low-level sonde data from July to August,2000 in Nanjing,the characteristics of thickness and intensity of low-level inversion (LLINV) are discussed,especially on their relations to urban surface temperature and relative humidity variation as well as their influence on body discomfort status.The result shows that there exists a distinct influence of LLINV on urban surface temperature,relative humidity,and their scope.The early LLINV reinforces the gain in temperature and the abatement in relative humidity from 08:00 to 14:00.On the contrary,the late LLINV cripples the abatement in temperature and the gain in relative humidity from 20:00 to 23:00.In addition,the index of body discomfort will be enhanced when LLINV appears.Finally,the regression equation on the intensity of LLINV and the body discomfort index is established,which provides a new way for quantificational prediction of the body discomfort index in operational weather service. |
