大气稳定度方法主要分为2 大类: 第一类是基于常规气象资料,利用地面风速、云量、日照强度等资料对大气稳定度进行判定,此种方法主要针对开阔平坦乡村地区,资料采用城郊气象站或飞机场气象站的气象观测资料,并未考虑特殊的下垫面,如城市、山地、水面等的动力和热力因子对稳定度的影响,只是半定量地给出稳定度扩散级别。第二类是基于高空气象资料,利用温度和风速的垂直分布情况,综合考虑动力因子和热力因子对稳定度的作用,更好地反映出风、温度等气象要素对大气稳定度的影响。

关键词: 大气稳定度, 温度, 风速


Methods about determination of atmospheric stability are divided into two categories. The first one is based on conventional meteorological data,surface wind speed,cloud amount,and sunshine intensity data to determine the atmospheric stability,and this method mainly for flat open rural areas,only using observations from the suburban or airport meteorological station without considering some influences of dynamic and thermal factors of specific underlying surface,such as cities,mountains,water - surface,etc. ,and making semi - quantitative diffusion level of atmospheric stability. The second one is based on the high - altitude meteorological data,making use of the vertical distribution of temperature and wind velocity,and considering the influence of dynamic and thermal factors on atmospheric stability,in order to better reflect influence of the wind,temperature and turbulence on atmospheric stability.

Key words: atmospheric stability, wind speed
