Evidence of a large region of mid-tropospheric dry air on AWIPS images of GOES-13 6.5 µm “water vapor channel” data (above; also available as a QuickTime movie) in tandem with an increase in Read More

Tropical Storm Earl formed in the eastern Atlantic Ocean on 25 August 2010. GOES-13 10.7 µm IR images from the CIMSS Tropical Cyclones site (above) revealed a well-defined circulation, with the development of convective clusters and curved bands.The environment around Earl was one that exhibited low values of 200-850 hPa deep layer wind shear...

McIDAS images of GOES-13 10.7 µm IR data (above) revealed a classic convective burst signature as Tropical Storm Danielle began to intensity over the middle Atlantic Ocean on 23 August 2010. The coldest cloud top IR brightness temperature during this time period was -90º C at 07:15 UTC.UPDATE: Danielle continued to intensify... Read More
