Tropical Storm Danny in the eastern Atlantic Ocean
The first tropical storm of the season in the eastern Atlantic (Ana, Bill and Claudette all formed over the western Atlantic) has formed from a cluster of thunderstorms that emerged from Africa. The multi-day animation, above, from GOES-13, shows the steady progress of the disorganized system across the eastern Atlantic basin. Visible Imagery from GOES-13 and Meteosat-10, below, from the morning of 19 August, show the system near 40 W. The cyclonic curvature to the clouds is apparent; identification of the center in infrared imagery, below, is more difficult. Convection to the east of Danny has colder cloud top temperatures.“Meteosat-10 0.6 µm Visible Image (Top, 1200 UTC) and GOES-13 0.63 µm Visible image (Bottom, 1145 UTC) on 19 August 2015 [click to enlarge]
