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)...

GOES-16 (GOES-East) “Red” Visible (0.64 µm) images (above) indicated that a strong arctic cold front (surface analyses) had plunged southward across Mexico, through the Chivela Pass, and emerged as a Tehuano (or “Tehuantepecer“) gap wind into the Gulf of Tehuantepec on 24 December 2020. Along the Gulf of Mexico coast, a few... Read More

GOES-16 (GOES-East) Visible (0.64 µm) images (above) revealed a cloud arc which marked the leading edge of a Tehuano wind event — air behind a cold front plunged southward across the Gulf of Mexico during the previous day, crossed the mountains of Mexico through Chivela Pass (topography) , and emerged over the Pacific...

After a strong arctic cold front plunged southward across the US, the Gulf of Mexico, and then southern Mexico during the previous two days (surface analyses), GOES-17 (GOES-West) and GOES-16 (GOES-East) “Red” Visible (0.64 µm) images (above) revealed the hazy plume of dust-laden Tehuano gap wind flow as it emerged from the...
