Summary: | The water quality pollution problem about feculent and anaerobic water aggregation (FAWA) induced by algal bloom in Taihu Lake, which is often called 'hufan' in Chinese, was studied. Its forming process is divided into 3 phases, i. e., material elements forming of FAWA, anaerobic products to be brought to the water surface and the maintaining of FAWA in the water surface. The conventional observational data from Wuxi meteorological station was analyzed. The result shows that there are similar meteorological characteristics of two FAWA phenomena in Taihu Lake in May, 2007 and May, 2008. A numerical simulation was performed to prove the analysis results. It indicates that propitious meteorological condition is one of the necessary forming factors of FAWA, which provides thermal and dynamical environment for FAWA. During the first phase, the weather conditions, such as high air temperature, gentle breeze and nearly invariable wind direction, maintain for more than 3 days and cause algal bloom to aggregate, then |
