Скачать или смотреть Destructive Tornado in Lee County, Alabama

A powerful tornado outbreak hit the southern U.S. on March 3, 2019, leaving damage across southern Alabama and Georgia, the Florida Panhandle, and parts of South Carolina. This GOES East “sandwich” imagery shows the storm that spawned a destructive tornado in Lee County, Alabama. The tornado caused at least 23 fatalities, and according to a National Weather Service preliminary assessment, it was at least an F3 and one-half mile wide or more.

This kind of imagery is known as a "sandwich” because it combines imagery from two of the 16 spectral channels offered by GOES-16's Advanced Baseline Imager: band 2 (a visible band) and band 13 (an infrared band). During processing, the transparency of the infrared band is increased and laid on top of the visible band. The result, as seen here, is imagery that offers spectacular views of storm attributes in rich detail. This approach retains both the cloud-top thermal structure as well as the finer visible band details such as over-shooting tops and transverse banding.
