摘要: 研究旨在客观分析2010年盛夏江苏气象部门环太湖人工增雨降温防控太湖蓝藻的实际效果,科学论证人工增雨防控蓝藻的可行性。收集增雨作业位置、时间等信息,结合高空风向风速,确定了作业影响区、非作业对比区。综合利用2个区域内气象站降水与气温观测资料、太湖蓝藻遥感监测资料,开展增雨效果区域回归分析、降温效果区域对比分析、作业前后太湖蓝藻面积变化实况分析。结果发现,人工影响天气作业后太湖地区平均增雨量达10.9 mm,增幅达11%,同时云中下沉气流增强,导致向地面输送的冷空气增强,太湖地区气温迅速下降,降幅1~2℃。增雨降温对防控太湖蓝藻初期繁生、中期扩展、降低污染起到积极的作用。

Abstract: In order to demonstrate the feasibility of prevention and control of Cyanophyta by artificial rain enhancement, the effect of artificial rain enhancement operations for prevention and control of Taihu Lake Cyanophyta launched by Jiangsu Meteorology Administration in 2010 summer was analyzed. According to the wind speed and direction in upper atmosphere and some operation information, such as place and time, the affected region by operations and unaffected contrast region were determined. The regional regression analysis of rain enhancement, contrast analysis of temperature decrease and real analysis of variation of the Cyanophyta area were conducted by application of the precipitation and temperature data from meteorological stations within the above two regions, as well as remote sensing data of Cyanophyta area around Taihu Lake. Results showed that after artificial rain enhancement, the increased magnitude of rainfall in Taihu Lake was 11%, reaching 10.9 mm, and the temperature decreased rapidly with 1-2℃, due to increased cold airflow to the ground result from enhancement of the downward flow in cloud. The early growth and medium-term expansion of Taihu Lake Cyanophyta were suppressed by the artificial rain enhancement and temperature decrease.
