Tropical Cyclone Strengthens Due to Volcanic Eruption

The MODIS satellite and ERA5 reanalysis data are used to evaluate the aerosol-cloud implications of Tongan volcano eruptions on adjacent tropical cyclones (TC) Cody on January 14-15, 2022. Although the sea surface temperature and vertical wind shear of the ambient wind did not alter much after the main blast of the Tongan volcanic eruption on January 15, the precipitation and intensity of Cody were clearly amplified. MODIS measurements on January 15 captured the vision of a considerable amount of volcanic aerosol flowing into the Cody influx from the Tongan eruption. Deep convection was detected in Cody when the cloud top temperature plummeted and the cloud particle effective radius was reduced.
