摘要: 利用改进的Bigg型混合云室于2011年5—11月在辽宁省气象局抚顺大气成分站对近地层大气冰核浓度进行了测量。根据测量结果,分析冰核浓度日际变化和季节变化特征,讨论了风、气压、气温和湿度以及天气状况等气象要素对大气冰核浓度的影响。结果表明:观测期间,抚顺市大气冰核浓度平均为30个·L-1(-20 ℃时);冰核浓度随活化温度的降低呈指数式增加;气象因子对冰核浓度有一定的影响,不同季节影响的程度不同。

Abstract: The atmospheric ice nuclei (IN) concentrations near the ground were measured in atmospheric composition station using an improved Bigg mixing cloud chamber in Fushun during May to November, 2011. The features of the diurnal and seasonal IN concentrations were analyzed and the effects of meteorological elements such as wind, air pressure, air temperature, humidity and weather situation etc. on IN concentrations were discussed. The results show that the average IN concentrations is about 30 L-1 (when activation temperature reaches -20 ℃) in Fushun during the observational stages. With the decline of activation temperature, the IN concentrations increase exponentially. The meteorological factors have a certain influence to the IN concentrations, and the influencing extent is different in the different seasons.
