TRMM Satellite Shows Possible Storm Development

The TRMM satellite had another revealing pass over the Mozambique Channel and Madagascar on 27 February 2012 at 2011 UTC. This area is being monitored for significant tropical cyclone development. TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) data were used in the rainfall analysis on the upper left. This analysis shows that very intense storms were being produced by a cyclonic circulation off northwestern Mozambique. These storms were dropping rainfall at a rate of over 50mm/hr (~2 inches) in the Mozambique Channel between Mozambique and Madagascar. The 3-D TRMM PR image on the

More Flooding Rainfall In Madagascar

A weak tropical cyclone locally called Irina caused flooding over northern Madagascar less than two weeks after deadly flooding by Tropical Cyclone Giovanna . The lastest tropical cyclone didn't have very strong winds when it passed over the coastal city of Vohemar on Madagascar's northeastern coast but street flooding was reported. The rainfall analysis above was made at the Goddard Space Flight Center using data from a near-real time Multi-satellite Precipitation Analysis (TMPA). TRMM-based near-real time Multi-satellite Precipitation Analysis (TMPA) data are used to monitor rainfall over

TRMM Sees Powerful Giovanna Menacing Madagascar

The TRMM Satellite had a fairly good early morning view of powerful tropical cyclone Giovanna approaching Madagascar on 13 February 2012 at 0333 UTC. Rainfall from TRMM Microwave Imager (TMI) data is shown overlaid on a visible/infrared image from TRMM's Visible and InfraRed Scanner (VIRS) instrument. Giovanna was an intensifying category 4 tropical cyclone with with wind speeds estimated at over 125 kts (~144 mph) and is predicted by the JTWC to become slightly more powerful before hitting Madagascar.

Giovanna Shown Becoming Dangerous

Tropical cyclone Giovanna was located in the Indian Ocean east-northeast of Madagascar when it was classified as a tropical storm on 9 Febuary 2012. The TRMM satellite image above shows Giovanna when it was rapidly becoming more powerful on 11 February 2012 at 1200 UTC. Giovanna had intensified to a category 3 tropical cyclone on the Saffir-Simpson scale with wind speeds estimated at 100 kts (~115 mph). This TRMM pass shows that an eyewall replacement was occurring at that time. A small ring of strong convective storms was located around the center of the center eye and other powerful storms

TRMM Sees Tropical Storm Striking Madagascar

The TRMM satellite has been collecting data that improves understanding of rainfall in the tropics since it's launch in 1997. The satellite also provides timely data about the development of tropical cyclones. One of these tropical cyclones called Chanda was hitting the coast of Madagascar when TRMM saw it on 8 January 2012 at 2213 UTC. A red tropical storm symbol is shown at Chandra's approximate location. Data from TRMM's Precipitation Radar (PR) and Microwave Imager (TMI) instruments shows that Chanda was dropping light to moderate rainfall over large areas of southern Madagascar. Deadly
