Storm track of Tomas (during the period 29 September - 05 November 2010)<\/p><\/div>\n

Tropical Storm Tomas became the 19th named storm of the 2010 Atlantic tropical cyclone season on 29 September 2010 (NHC advisory archive<\/a><\/strong>). The path of Tomas from the CIMSS Tropical Cyclones<\/a><\/strong> site can be seen above, along with a plot of the Advanced Dvorak Technique<\/a><\/strong> (ADT) intensity estimate (below)<\/em><\/strong> which showed that there were a number of fluctuations in the intensity of Tomas: it initially intensified into a Category 1 and then a Category 2 hurricane as it crossed the Windward Islands of the Lesser Antilles on 30-31 August, but then was degraded to a Tropical Storm due to unfavorable deep layer wind shear on 01 November. Atmospheric steering currents then helped Tomas turn to the north, and the storm re-intensified into a Category 1 hurricane as it passed between Cuba and Hispaniola on 05 November.<\/p>\n

A comparison of a GOES-13 10.7 \u00c2\u00b5m IR image with the corresponding SSMI\/S 85 GHz microwave image around 22:45 UTC on 30 August (below)<\/em><\/strong> showed that Hurricane Tomas had a large closed eye and a well-defined spiral band extending northward as the storm passed to the west of the Windward Islands of St. Lucia and St. Vincent.<\/p>\n

On 05 November, AWIPS images of POES AVHRR<\/a><\/strong> 10.8 \u00c2\u00b5m IR data (below)<\/em><\/strong> showed that Hurricane Tomas was exhibiting IR brightness temperatures as cold as -93\u00c2\u00ba C<\/strong> (darker purple color enhancement)<\/em> as the storm passed between Jamaica and Hispaniola.<\/p>\n

Note the improvement in cloud top temperature structure that can be seen on the 1-km resolution POES AVHRR IR image, compared to the corresponding 4-km resolution GOES-13 IR image (below)<\/em><\/strong>. On the POES AVHRR image, subtle storm top gravity waves can be seen emanating southward away from the region of coldest cloud tops, and the transverse banding structure along the western and southwestern edge of the storm are better resolved.<\/p>\n
