TRMM Satellite Image of Tropical Cyclone Yasi

Image Caption

TRMM Satellite image of Tropical Cyclone Yasi on February 1st to 3rd, 2011 (left to right) as it made landfall over Queensland, Australia.

TRMM’s TMI and PR instruments observed Cyclone Yasi as it developed from a Category 3 tropical cyclone (Feb. 1st, left), to a Category 5 event (Feb. 2nd) when it made landfall with wind gusts reported at up to 186 mph, and then finally as it began to dissipate on Feb. 3rd (right).

TRMM Sees Diminished CHERENO (18S)

Tuesday, March 22, 2011

The TRMM satellite passed directly above the remnants of tropical cyclone CHERENO (18S) in the South Indian Ocean on 22 March 2011 at 0225 UTC. TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) show that CHERENO, although weakened, still had some life and was producing very heavy rainfall of over 50 mm/hr (~2 inches) south-southeast of Reunion Island.

Rainfall Near ARANI Subsides

Friday, March 18, 2011

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
