Employing geostationary satellite to examine the physical properties of cloud tops for thunderstorm gusts

By the use of the Fengyun-4A geostationary satellite's multi-channel brightness temperature data (FY-4A). Examined and contrasted the physical properties of the cloud tops for three distinct thunderstorm gust episodes, each with varying intensities and ranges. The following outcomes from the analysis: Updrafts in convective clouds must achieve a specific range and strength. Positive BTD1(the difference between the infrared and water vapor channels) scores are also found in regions with wind speeds higher than ten levels. These regions experience freezing, a thickening of the cloud top, and a brightness temperature gradient greater than 20K. These regions are generally seen in front of the direction that clouds are moving. By using criteria such as BTD1 greater than 0 K, cloud top brightness temperature gradient greater than 20K can made preliminary judgments on the convective areas that could produce hazardous weather.
