小型水体对气温观测环境影响的初步模拟分析
A preliminary simulation analysis on effects of water body on air temperature observation environment
摘要
Abstract
In order to research the effects of water body on temperature observation environment at meteorological stations,through comparing the case simulation results with or without water bodies,the impacts of Qingshan Lake(6.5 km2) in Zhejiang province on the surrounding air temperature at 2 m by u sing WRF model were analyzed under the weather background of clear sky with light wind and cloudy sky with gale in four seasons,respectively.Results show that (1) water body would increase leeward air tem perature greater in winter than in spring and autumn due to the stable weather condition,while in summer,the influence of water body was not so obvious because of the complex local thermodynamic circulation.(2) The Qingshan Lake has obvious effects on the air temperature at a distance of 5 km from the lake leeward and 0.4 km in other directions.(3) The larger the water body area is,the longer the affecting distance of surrounding air temperature is.(4)When the wind speed is higher than 6.2 m·s-1,the thermodynamic property divergence between water and land would be quickly carried away by advection,so the effect was not obvious.And then the turbulent diffusion would transmit the thermodynamic property divergence upward,so the effects became not so obvious when the turbulence intensity was larger than 0.5 m2· s-2.关键词
