Himawari-8 as a new generation geostationary meteorological satellite can provide the observation data for dynamically monitoring of Cyanobacteria bloom,with high time resolution at an interval per 10 minutes.According to the spectrum measuring data of Lake Taihu area,a method using the Himawari-8 data was proposed for dynamically monitoring of the Cyanobacteria bloom.In this paper,the outbreak processes of Cyanobacteria bloom on October 2nd,2015 were monitored continuously including the Cya-nobacteria bloom's appearing,increasing and disappearing.The dynamic changes of the intensity and speed of Cyanobacteria bloom were calculated,and the extent and variation were analyzed.All the analysis provided useful information for studying the growth and death of Cyanobacteria bloom.Furthermore,this paper discussed the relation between Cyanobacteria bloom's dynamic changes and meteorological elements of temperature and humidity under the same conditions.Results showed that wind is a direct driving effect on appearing,increasing and disappearing of the Cyanobacteria blooms.
