郑州市CO中毒事件气象条件分析

Meteorological Condition Analysis on Carbon Monoxide Toxic Matters in Zhengzhou

冬季是CO中毒的多发季节。针对2007年1月1-3日郑州市所发生的CO中毒事件,从天气形势、逆温情况、气象要素特征等方面进行了分析。结果表明:气压梯度小、近地层逆温明显、风力小、温度低、湿度大、云量多等气象条件都是造成中毒事件的有利气象因素;又因天气寒冷,放假期间人们大多待在家中,因此煤气中毒事件较平时激增了数倍。

The carbon monoxide toxic matters often occur in winter. The paper analyzed those matters that occurred during January 1 - 3 in 2007 in Zhengzhou from some aspects such as weather situation, inversion situation and meteorological factors feature. The result shows that less pressure gradient, obvious inversion of ground layer, less wind force, lower temperature, bigger humidity and more cloudiness are advantaged meteorological factors for resulting in toxic matters. On the other hand, because it was very cold and many people had to stay at home enjoying their holidays, the gas poisoning matters increased many times than in peacetime.
