Tehuano wind event

ASCAT winds from Metop-B and Metop-C [click to enlarge]

A sequence of ASCAT winds (source) from overpasses of Metop-B and Metop-C at 0314, 0407, 1548 and 1607 UTC on 03 January 2022 (above) showed the early emergence of Tehuano gap winds into the Gulf of Tehuantepec, followed by their spread south-southwestward across the Pacific Ocean.

GOES-16 Shortwave Infrared (3.9 µm) images (below) revealed a cooling trend within the Gulf of Tehuantepec during the 0500-2100 UTC period — with water surface 3.9 µm brightness temperatures dropping from around 24ºC (orange enhancement) to 18ºC and below (yellow enhancement) — as the strong gap wind flow induced upwelling of colder water.

The offshore transport of airborne dust was evident in GOES-17 True Color RGB images created using Geo2Grid (below).
