Hurricane Ian--Verisk AER GOES East Meteorological Satellite data in review

Hurricane Ian--Verisk AER GOES East Meteorological  Satellite data in review

In this post we share some Verisk AER  imagery loops of Hurricane Ian sourced from the GOES-East platform. Stay tuned for more imagery loops provided from our R&D and Advanced Science and Technology divisions.

On September 28, 2022, Hurricane Ian made US landfall on Florida's southwestern coast as a high-end category 4 storm. Hurricane Ian’s top maximum sustained winds of 155 mph had been recorded hours before landfall, when the Category 4 hurricane was 2 mph shy of reaching Category 5 classification.

GOES-East color composite image loop of Hurricane Ian for the 5-day period beginning 00 UTC Tues 27 Sep 2022. In this sequence, multispectral sensor data provided by the Advanced Baseline Imager (ABI) contains information on cloud characteristics that help discriminate cloud phase (liquid or frozen). When displayed in color composite form, the images illustrate Ian’s complex vertical structure by differentiating low (liquid) from high (frozen) clouds. Low/high clouds appear red/blue in the nighttime frames, and yellow/blue in the daytime frames. Counter-clockwise low cloud movement highlights Ian's cyclonic low-level inflow, while clockwise movement of the high cirrus clouds highlights the upper-level outflow. The intensity of the upper-level outflow in this storm is exhausting large quantities of moisture into the southwesterly jet stream, demonstrating the prolific ability of tropical storms to transport heat and moisture in the atmospheric global circulation.
