上海地区雨水酸度与天气背景的关系

Relationship between the acidity of precipitation and the synoptic situation in Shanghai

  • 摘要: 1981—1983年在上海地区11个观测站进行了雨水pH值观测,取到资料2448份.从资料分析得到:(1)雨水pH值与天气背景有关,静止锋天气影响时,酸雨出现几率达44.5%,雨水较酸;暖锋天气时,酸雨出现几率仅9%.(2)台风、高压边缘天气影响下,酸雨的形成主要是受局地污染源的影响;但静止锋、冷锋、低压系统天气时,酸雨的形成不仅受局地污染源的影响,而且还可能受随气流输送来的外来污染物的影响.
