Tóm tắt

Direct evidence demonstrates that urban and industrial air pollution can completely shut off precipitation from clouds that have temperatures at their tops of about –10°C over large areas. Satellite data reveal plumes of reduced cloud particle size and suppressed precipitation originating from major urban areas and from industrial facilities such as power plants. Measurements obtained by the Tropical Rainfall Measuring Mission satellite reveal that both cloud droplet coalescence and ice precipitation formation are inhibited in polluted clouds.

I thank all the members of the TRMM team too numerous to mention individually for all their hard work to make the satellite a reality and the data of such high quality. The NOAA AVHRR data were obtained from the NOAA Satellite Active Archive. I also thank A. Gingis of Australian Management Consolidated Pty. Ltd. for assisting in this study and W. L. Woodley for help with the manuscript.
