摘要:

2008年1月10日以来我国发生了大范围持续性低温雨雪冰冻极端天气灾害,在1月29~31日雨雪已止、天气转晴的三天内,于合肥地区进行了多种大气参数包括温度、相对湿度、风速、湍流折射率结构常数、气溶胶粒子谱分布、数浓度、散射系数和吸收系数等的连续观测,获得了一批与冬季常规观测明显不同的实验结果。给出了这一个例中大气气溶胶的变化特征。

Abstract:

Atmospheric physics and optical properties in science island, Hefei were continuously measured and statistically analyzed from January 29 to 31, in 2008. The characteristic parameters, such as temperature, relative humidity, wind velocity, turbulence refractive index constant, size distribution of aerosol particles, total number concentration, scattering coefficient and absorption coefficient were measured synchronously. Some of statistical results had distinct difference with results of routine measurement in winter. The variation of aerosol in the case was discussed.

Key words: atmospheric optics, heavy snow, turbulence refractive index constant, physical property, optical property
