GOES-16 (GOES-East) Mid-Level Water Vapor (6.9 µm) and Air Mass RGB images (above) covered the period 0600-1800 UTC on 03 November 2022 — during which Category 1 Hurricane Martin transitioned to an extratropical cyclone over the North Atlantic Ocean (surface analyses). West of Martin, the large area of orange-to-red hues on the Air Mass... Read More
1-minute Mesoscale Domain Sector GOES-16 (GOES-East) “Clean” Infrared Window (10.3 µm) images (above) showed that Hurricane Julia made landfall as a Category 1 intensity storm along the east coast of Nicaragua around 0715 UTC on 09 October 2022. A notable increase in the areal coverage of deep convection was seen around the center... Read More
Polar-orbiting satellites have microwave detectors that give important information about the low-level structure of an evolving tropical cyclone. If high clouds are omnipresent, it can be difficult for an analyst to diagnose storm strength with accuracy. Microwave energy penetrates clouds, however, and low-earth orbit (LEO) observations of microwave frequencies can... Read More
Sentinel overflew Tropical Storm Gaston, northwest of the Azores Islands, shortly before 0800 UTC on 23 September 2022, as shown above. The Beaufort Scale enhancement suggest peak winds derived from SAR observations to be very close to 50 knots in curved bands to the east/southeast of the center, inferred to... Read More
