包头市区冬春季负氧离子浓度变化与气象要素关系初探

文章利用2011年11月至2012年5月包头市逐日负氧离子实况资料,分析了负氧离子冬春季、月和日变化特征及其与相关气象要素的关系。结果表明:包头市负氧离子浓度具有明显的季节、月和日变化,春季负氧离子浓度明显高于冬季,月平均最小浓度值出现在1月,最大浓度值出现在5月,夜间负氧离子浓度高于白天;负氧离子浓度变化与相关气象要素关系密切:月平均浓度与月平均气温、降水量呈正相关。

Fluctuate of Negative Oxygen Ion Concentration and Its Influence of Meteorological Elements in Winter and Spring of Baotou

Based on the observation data of negative oxygen ion concentrations and meteorological data from November in 2011 to March in 2012 in Baotou,the seasonal,monthly and daily variations of negative oxygen ion concentrations,and relationships between negative oxygen ion concentrations and meteorological factors were analyzed.The results show that negative oxygen ion concentrations are obviously different in different seasons,months and days.Negative oxygen ion concentrations are higher in spring than in winter,the minimum concentration appear in January,the maximum concentration is in May,negative oxygen ion concentration is lower in the daytime than in the night;The negative oxygen ion concentration has close correlation with meteorological elements;The monthly average concentration of negative oxygen has positive correlation with monthly average;temperature and moisture.
