Cyclone Imelda has lost both her punch and her hurricane status as the storm moved into an area of higher wind shear and cooler waters in the Southern Indian Ocean. NASA‘s Aqua satellite provided an image of Imelda that showed wind shear that has been hammering the storm, had pushed the bulk of the storm’s precipitation southeast of the center.
Tropical Cyclone Victoria is now a remnant low pressure area in the Southern Indian Ocean after running into strong wind shear that has been tearing the storm apart. When NASA’s TRMM satellite passed over the storm on April 12 it saw limited areas with moderate rainfall pushed far from the center of circulation.
An upper-level low pressure system is sapping the cloud and thunderstorm development on the western side of Cyclone Victoria in the Southern Indian Ocean. New NASA satellite imagery showed that the bulk of rainfall was located east of the storm’s center.
When NASA‘s Aqua satellite flew over Cyclone Victoria in the Southern Indian Ocean it captured a visible image of the storm and it appeared to look like the letter “J.” A band of thunderstorms wrapping into the center from the east of low-level center of circulation extended north, creating the appearance of the letter.
In the wake of Cyclone Rusty‘s heavy rains from the week of Feb. 25 when it made landfall near Port Hedland on the Pilbara coast of Western Australia, sediment filled many rivers and tributaries that flowed northwest into the Southern Indian Ocean. …read more

The eighteenth tropical cyclone of the Southern Indian Ocean season formed over the weekend of Feb. 23-24 along with Cyclone Rusty as Cyclone Haruna crossed southern Madagascar. NASA‘s Aqua satellite measured Tropical Storm 18S’ cloud top temperatures and saw powerful thunderstorms around the storm’s core. …read more

Ex-cyclone Haruna is expected to dissipate in the Southern Indian Ocean under increasing wind shear in the next day or two. Infrared imagery from a NASA satellite shows that Haruna is being blown apart several hundred miles away from La Reunion Island. …read more

Cyclone Felleng traveled through the Mozambique Channel during the week of Jan. 28, 2013 and emerged south into the Southern Indian Ocean where it transitioned into a cold core low pressure area. NASA‘s TRMM satellite captured a look at the rainfall rates occurring in Felleng as it was making that transition on Feb. 1.

NASA‘s TRMM and Aqua satellites showed how Tropical Cyclone Narelle has fallen far from being a powerful cyclone in the Southern Indian Ocean. A time series of infrared images from an Aqua satellite instrument provides a clear picture of Narelle’s former power and its recent demise, while TRMM 3-D data showed falling cloud heights and weaker rainfall.

Tropical Cyclone Emang developed in the Southern Indian Ocean on Sunday, Jan. 13 about 525 nautical miles east-southeast of Diego Garcia. At that time, infrared satellite imagery revealed that the low level circulation center was partially exposed to outer winds, and there was a burst of thunderstorm development over the northwestern quadrant.

The eighth tropical cyclone to form during the Southern Indian Ocean cyclone season formed from low pressure System 98S and became Tropical Cyclone Narelle. NASA‘s TRMM satellite passed over System 98S and saw the hallmark “hot towers” that indicated the storm would soon likely intensify into Tropical Storm Narelle.
