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
A vigorous extra-tropical cyclone moving towards the western Great Lakes on 11 November 2021 generated significant winds and waves over Lake Superior. RADARSAT winds, above, from RCM1, (available at this website) show a large area of southeasterly winds between 30 and 40 knots at 1159 UTC on 11 November. Regions of... Read More
