Based on the knowledge of transport, diffusion, removal and transformation of air pollution, precipitation chemistry, and cloud mierophysics, a Lagrangian puff trajectory model, adopted in the study of regional acid precipitation is designed. The distributions on the acid rains of six continuous precipitation processes in Chongqing during the period July to October 1982 are simulated with the model. The results show that the source of acid rain in the Chongqing area is air pollution itself, which corresponds...

Based on the knowledge of transport, diffusion, removal and transformation of air pollution, precipitation chemistry, and cloud mierophysics, a Lagrangian puff trajectory model, adopted in the study of regional acid precipitation is designed. The distributions on the acid rains of six continuous precipitation processes in Chongqing during the period July to October 1982 are simulated with the model. The results show that the source of acid rain in the Chongqing area is air pollution itself, which corresponds with the facts of lower effective stack height and slight wind in the city. The mechanism for the formation of the acid precipitation here may be different from that in the United States of A-merica and West Europe, where acid precipitations appear in the area far from pollution source with a great effective stack height.

在大气污染物的输送、扩散、迁移、转化、降水化学和微观云物理等方面国内外已有的认识基础上,本文设计了一适用于区域性酸雨研究的拉氏烟团轨迹模式,用此模式模拟了重庆市1982年7—10月的6个连续降水过程的酸雨分布.结果表明,重庆酸雨的来源主要是自身污染造成的,这与该市污染源排放低、风小的事实一致、这种类型的酸雨和美国、西欧由超高烟囱排放造成的在污染源下风方很远区域形成的酸雨从机理上可能有所不同.

A method for collecting rime ice and snow samples are described. The both samples, which were collected during 8 supercooled clouds cases in winter at whiteface Mountain, New York, were analyzed for PH and the various ions. It is shown that the ion concentrations in rime ice are higher than that in snow with higher PH generally. A winter field-laboratory experiment which measured the chemical composition of frost, formed at sampling site, indicated that the ion concentrations in frost were much lower than that...

A method for collecting rime ice and snow samples are described. The both samples, which were collected during 8 supercooled clouds cases in winter at whiteface Mountain, New York, were analyzed for PH and the various ions. It is shown that the ion concentrations in rime ice are higher than that in snow with higher PH generally. A winter field-laboratory experiment which measured the chemical composition of frost, formed at sampling site, indicated that the ion concentrations in frost were much lower than that in rime ice and demonstrated that Bergeron-Findeison process occurring in supercooled clouds is one of the main reasons to cause the differences of PH and the ion concentiations between in rime ice and in snow. The vari-a tion in seasonal precipitation composition may in part be due to Bergeron-Findeison process.

本文介绍了收集雾淞和雪样的方法。对1983年冬——1984年春在纽约州Whiteface山收集的8个冷云系统的雾淞和雪样的化学组份分析表明:雾淞中的PH值均比雪中的低;除少数例子外,雾淞中的离子成分含量一般都高于雪。实验表明,霜样中的离子浓度比雾淞中的低得多。这证明,过冷云中的Bergeron—Findeison过程是造成雾淞和雪PH值和离子浓度差别的主要原因,这可部份地解释降水化学成份的季节变化。

This paper deals preliminarily with the chemical components of the rainfall and the leaching feature of crown layer through contrast observation within semideciduous monsoon rain forest in Jianfengling Mountain Hainan Island. The leach of crown layer is one of the functions of forest in regulating rainfall and also an important .way of material circulation in forest ecosystem. Shifting agriculture seems increased some elements of rainfall but it loses with the surface runoff and is no use to plants and soils....

本文通过对比观测,初步探讨了海南岛尖峰岭半落叶季雨林区降水的化学成分及冠层淋溶的特点。冠层淋溶是森林调节降水的功能之一,是森林生态系统物质循环的重要渠道。“刀耕火种”似可增加降水中采些元素的含量,但随地表迳流而流失,无益于植物和土地。
