Tropical cyclone LEHAR, located in the Bay Of Bengal, continues to gain intensity while heading toward the same area of India where a much weaker tropical cyclone HELEN recently came ashore. The Joint Typhoon Warning Center (JTWC) predicts that LEHAR's sustained wind speeds will reach 95 kts (~109 mph) on November 27, 2013 and then decrease to about 85 kts (~98 mph) before hitting India's east-central coast. The TRMM satellite flew above tropical cyclone LEHAR on November 26, 2013 at 0307 UTC and captured data used in the image above. Rainfall derived from TRMM's Microwave Imager (TMI) and
Today tropical cyclone LEHAR's estimated sustained wind speeds reached 65kts (~75 mph). The most powerful tropical cyclone in the Bay Of Bengal this year was deadly tropical cyclone PHAILIN that moved through the area in October with wind speeds of 140kts (~161 mph). This means that LEHAR is the second most powerful tropical cyclone to form in the Bay Of Bengal this year. The TRMM satellite collected data used in the image on the left when the TRMM satellite passed above LEHAR on November 24, 2013 at 1812 UTC. At that time LEHAR was intensifying with tropical storm force winds estimated to be
Tropical cyclone Helen was the fourth named tropical cyclone in the Bay Of Bengal this year when it formed on November 19, 2013. The image on the left shows tropical cyclone Helen as the TRMM satellite flew over on November 21, 2013 at 0606 UTC when Helen had reached peak intensity of about 60kts (~69 mph). The image on the right uses data captured on November 22, 2013 at 0510 UTC when tropical cyclone HELEN was hitting India's east-central coastline. Precipitation data derived from TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) instruments show that Helen was dropping rain at a
Mexico's Pacific and Gulf coasts were both inundated by deadly tropical rainfall at the same time. Tropical storm Manuel dropped extremely heavy rainfall along Mexico's Pacific coast. At least 55 people have been reported killed in Mexico due to flooding and landslides caused by extreme rainfall. Hurricane Ingrid weakened to a tropical storm and came ashore from the Gulf Of Mexico into the state of Tamaulipas near La Pesca, Mexico on Monday September 16,2013. The approximate 0000Z and 1200Z locations of the tropical cyclones are shown overlaid in white. The TRMM-based, near-real time Multi-
A low pressure center associated with a strong tropical wave near the African coast of Senegal may become a tropical depression south of the Cape Verde islands in the next five days. The TRMM satellite collected data used in the image above when it flew over this tropical disturbance on September 7, 2013 at 0257 UTC.
Tropical cylone Mahasen hit southern Bangladesh causing the reported deaths of at least 12 people and the destruction of many homes. Mahasen had heavy rains accompanied with tropical storm force winds when it came ashore. The TRMM satellite had two very informative views as deadly tropical Cyclone Mahasen was moving toward and then over Bangladesh. TRMM passed above Mahasen on May 15, 2013 at 2133 UTC and saw Mahasen again on May 16, 2013 at 0406 UTC after the tropical cyclone's center passed over Bengladesh's Ganges Delta. Red tropical cyclone symbols mark Mahasen's locations with both TRMM
The TRMM satellite passed above a developing tropical cyclone in the northern Indian Ocean west of Indonesia on May 9, 2013 at 2211 UTC. This image shows that tropical cyclone 01B was already fairly well organized. TRMM's Precipitation Radar (PR) instrument indicated that rainfall was falling at a rate over 178 mm/hr (~5.8 inches) in an area of strong convection in the middle of the forming tropical cyclone. The tropical cyclone is a little unusual because it formed only 4.8 degrees north of the equator. Coriolis force, an artifact of the earth's rotation, is weaker near the equator so
The TRMM satellite flew directly over an intensifying tropical cyclone called Imelda in the South Indian Ocean on April 8, 2013 at 0447 UTC. This rainfall analysis used data collected with TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) instruments. This analysis shows a large area of rainfall on the western side of the developing tropical cyclone. TRMM PR found that some powerful convective storms in this area were dropping rain a rate of over 86mm/hr (~3.4 inches).
Tropical cyclone Sandra formed in the Coral Sea south off the Solomon Islands on March 7, 2013. Sandra intensified over the open waters of the Coral Sea and became a very powerful tropical cyclone with winds of about 110 kts (~127 mph). Sandra has started weakening but is predicted to buffet northern New Caledonia with tropical storm force winds on March 12, 2013. Sandra's approximate past and forecast locations are shown overlaid in white. The TRMM satellite passed above Sandra on March 10, 2013 at 2219 UTC. A rainfall analysis using data captured by TRMM's Microwave Imager (TMI) instrument
On March 11, 2013 the TRMM satellite twice flew above weakening tropical cyclone Sandra as it was passing to the west of New Caledonia in the southern Pacific Ocean. TRMM's Precipitation Radar (PR) had a very good view of Sandra as it passed directly above the tropical cyclone on March 11, 2013 at 1312 UTC. TRMM PR measured rainfall at the extreme rate of over 206 mm/hr (~8 inches) in an area southwest of Sandra's eye. Those TRMM PR data also showed that very little rain was occurring north of the weakening tropical cyclone's eye. Click here to see a simulated Flyby over Sandra using 3-D TRMM
