ARANI

The image above shows subtropical cyclone ARANI as the TRMM satellite passed over head on 17 March 2011 at 0958 UTC. TRMM Microwave Imager (TMI) and Precipitation Radar (PR) data from that orbit show that moderate to heavy rainfall was only occurring to the southeast of ARANI at that time. TMI and PR rainfall data were overlaid on a combination visible and infrared image that used TRMM Visible and InfraRed Scanner (VIRS) data. Visible low level clouds from this image (shown in shades of yellow) are the only evidence for the location of ARANI's center of circulation. Click here to see earlier

The TRMM satellite had another very good view of subtropical cyclone ARANI in the morning light on 16 March 2011 at 1052 UTC. This orbit showed that there were very heavy thunderstorms in the eastern half of the storm. TRMM's Precipitation Radar (PR) showed that some of these powerful storms were reaching to heights of over 14 km (~8.7 miles) above the surface of the south Atlantic Ocean.
