Humberto

The TRMM satellite had another good daytime look at tropical storm Humberto on September 17, 2013 at 1639 UTC (12:39 PM EDT). Rainfall data from TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) are shown overlaid on a visible/infrared image from TRMM's Visible and InfraRed Scanner (VIRS). The most intense echo found by TRMM PR was 48.3dBZ with rain falling at a rate of 56.5mm/hr (~2.22 inches) in an area north-northeast of Humberto's center. A red tropical storm symbol shows Humberto's approximate circulation center location.

Tropical storm Humberto, located in the eastern Atlantic Ocean, had little deep convection and was classified by the National Hurricane Center (NHC) as a post-tropical cyclone on September 14, 2013. On September 16, 2013 Humberto was having bursts of strong convection and was again classified a tropical storm. Humberto was viewed during the daytime by the TRMM satellite on September 15, 2013 at 1652 UTC (12:52 PM EDT) and on September 16, 2013 at 1557 UTC (11:57 AM EDT). These TRMM orbits show the significant changes that occurred within Humberto's in less than 24 hours. In the first orbit on

Southwesterly wind shear has taken it's toll on hurricane Humberto. An eye was no longer distinct in data collected when the TRMM satellite passed over on September 12, 2013 at 1625 UTC (12:25 PM EDT). An analysis derived from TRMM Microwave Imager (TMI) and Precipitation Radar (PR) data shows that most of the precipitation with Humberto was then located in the northwestern quadrant. TRMM found that the most intense rain was falling at a rate of over 99mm/hr (~3.9 inches) at 22.4 North 28.7 West near Humberto's center. TRMM PR also found that the highest storm towers were reaching heights of

The TRMM satellite had an excellent daytime view of strong tropical storm Humberto on September 10, 2012 at 1636 UTC (~12:36 PM EDT). Rainfall derived from TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) data are shown overlaid on a combination visible/infrared image from TRMM's Visible and InfraRed Scanner (VIRS). TRMM PR found that the heaviest rainfall associated with Humberto was not near the center of circulation but in convective storms west of the storm. Tropical Storm Humberto's highest winds were about 55kts (~63 mph) at the time of this TRMM pass and the National Hurricane
