Observation and analysis of typhoon Meranti by multiple satellite sensors Abstract Typhoon "Meranti" landed on Xiamen Coast on Sep. 15, 2016, causing serious meteorological disasters and economic losses. As the human life has been influenced heavily by typhoon, it is very critical to monitoring and tracking its behaviors and parameters. Satellite remote sensing with its ability of wide coverage provides an efficient way to study typhoon. The paper tries to analyze typhoon "Meranti" by multiple satellite sensors, such as Sentinel-1’s synthetic aperture radar (SAR), WindSat’s radiometer, and MODIS’s sensors, to improve the estimation of its strength, the location of typhoon eye, and the structure of wind and pressure. The high-resolution SAR images were used to retrieve the wind field in some local areas, combined with the WindSat’s wind field to obtain a more detailed structure of typhoon. The result shows that the observation of typhoon by multiple satellite sensors may offer useful wind information for typhoon monitoring and forecasting.
