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 True-Color imagery from the CSPP Geosphere site (link showing the data above) on 26 November, above, show features associated with strong flow through Chivela Pass in southern Mexico, gap winds often called Tehuano winds or Tehuantepecers. Strong descent associated with these events can often limit the presence of clouds that... Read More
From an email came this question: RADARSAT vs ASCAT winds, what are the differences between the two methods?This comparison is not easy to make directly, as the orbits of Metop-B and Metop-C, the two satellites that carry the ASCAT instrument (now that Metop-A, which satellite also carried ASCAT, has been decomissioned), don’t...

The polar orbiting satellite Metop-A was switched off on 15 November 2021, ending a very long career gathering information (the satellite was launched in 2006). The final ASCAT (ascending) imagery from Metop-A, from this site, is shown above (click here to see the descending data from that day). ASCAT scatterometery from... Read More
