The Satellite and in-situ observations of extreme climate and disasters over One Belt & One Road region (funded by the Strategic Priority Research Program of the Chinese Academy of Sciences) project team aims at satellite and in-situ observations of some extreme disasters, such as dust storm, tropical cyclone, heat wave, drought, and snow, to evaluate the intensity of extreme disasters and reveal their evolution with global climate change.
Dust aerosol plays an important role in the interaction and feedback process with the environment, weather and climate, and it also contributes greatly to many kinds of diseases and economic loss. In order to mitigate the impact of dust storms, we monitored the dust storm transportation using FY-4, Himawari-8, MODIS, AVHRR, and CALIPSO satellite data. Combined with meteorological reanalysis data, we analyzed the starting, development and deposition mechanism of dust storms. Now, we focus on the effect of dust storms originating from east Asia on the ocean eutrophication over Western North Pacific.
Through some Geostationary Meteorological Satellites, such as FY series and Himawari, and some polar orbit satellites with high spatial resolution, we can get the structure of typhoon, rain intensity and wind speed with higher precision. We explored the variation of typhoon structure, wind fields, and rain intensity during rapid intensification process. We devote to figuring out the differences of those aforementioned features between different intensity change categories, which will be applied in intensity monitoring.
In order to achieve near real time monitoring through multi-satellites, integrated system or platform should be established, and further researches are needed.
