Analysis Of Spearman Rank Correlation & Linear Regression Of Atmospheric Stability And Cloud Tops Temperature Of Himawari-8 IR Satellite Images (Case Study Of Hail On May 22, 2022)

This research is based on cases of hail that caused flooding in Binjai City May 22, 2022. study aims to see the correlation and regression Atmospheric Stability index value cloud top temperature data from Himawari-8 satellite imagery. So ERA-5 reanalysis can be used obtain temperatures predicting events. The indices this are CAPE, KI TTI. located with testing 00UTC – 24UTC Supported form sea surface wind conditions looks at causes location. method Spearman's rank results obtained a K -0.651, TT -0.563, CAPE -0.348. simple linear also show negative gradient line. shows increase stability line decrease temperature. as benchmark estimating case convective formation which hail.
