A NOAA-17 InfraRed (IR) image (above) depicted a well-defined eye and eyewall structure associated with Category 4 Cyclone Sidr while it was located over the Bay of Bengal on 15 November 2007. The CIMSS Advanced Dvorak Technique (ADT) intensity estimate around that time was 146 knots.Animations of the Morphed Integrated Microwave Imagery at CIMSS (MIMIC)... Read More
Meteosat-7 IR images sourced from the CIMSS Tropical Cyclones site (above) showed Category 4 intensity Tropical Cyclone Sidr as it moved northward across the Bay of Bengal on 14 November 2007. Increasing amounts of deep layer wind shear (below) to the north of the storm may act to diminish the intensity of... Read More
Hurricane Noel remained a minimal Category 1 hurricane early in the day on 02 November 2007, although the satellite presentation was starting to deteriorate (GOES-12 IR animation) as the storm began the transition to an extratropical system. SeaWinds scatterometer data from the QuikSCAT satellite around 10:48 UTC (above, and below) did show two wind retrievals... Read More
Tropical Storm Noel intensified late in the day on 01 November 2007 to become a minimal Category 1 hurricane just north of the Bahamas. AWIPS images of the GOES-12 10.7µm IR channel (above) show that the circular area of very cold cloud top temperatures (colder than -80º C, green enhancement) became more... Read More
