TRMM

Today TRMM satellite also flew above tropical storm Leepi just to the east of the Philippines at 0947 UTC. Data from TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) instruments found the most intense rainfall in powerful storms near Leepi's center and in rain bands spiraling into Leepi from the south. TRMM PR data were used to make this 3-D view of tropical storm Leepi's vertical structure. Some of the powerful storms near Leepi's center reached heights above 16.5km (~10.25 miles). Tropical storm Leepi is predicted by the Joint Typhoon Warning Center (JTWC) to increase slightly in

Tropical Storm Andrea formed on the late afternoon of June 5th, 2013 from a trough of low pressure that had persisted for several days over the southeast Gulf of Mexico. This trough extended out over the Gulf from the Yucatan Peninsula and provided the focus for the development of showers and thunderstorms in the region, eventually leading to the formation of Tropical Storm Andrea. With its suite of passive microwave and active radar sensors, TRMM is ideally suited to measure rainfall from space. For increased coverage, TRMM is used to calibrate rainfall estimates from other additional

The TRMM satellite satellite flew directly above tropical storm Andrea on Wednesday June 5, 2013 at 2234 UTC (6:34 PM EDT) and received data used in the image on the left. These data were captured just over an hour after the National Hurricane Center (NHC) named tropical storm Andrea. A rainfall analysis from TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) instruments shows that moderate to heavy rain was wrapping around the eastern side of the storm. The heaviest rainfall of 124.5 mm/hr (~4.9 inches) from TRMM PR data was found on Andrea's southeast side. TRMM had another fairly

Last week's flooding and tornadoes caused the reported deaths of at least 18 people in Oklahoma. Today extensive flooding from heavy rainfall occurred in Missouri when a levee was breached. The TRMM-based, near-real time Multi-satellite Precipitation Analysis (TMPA) at the NASA Goddard Space Flight Center was used in this analysis to show rainfall over these areas. TRMM with its combination of passive microwave and active radar sensors was used to calibrate rainfall estimates from other satellites. TMPA rainfall totals are shown here for the 21-day period from May 14 to June 4, 2013. Heavy

Hurricane Barbara recently made landfall along the southern Pacific coast of Mexico. According to the National Hurricane Center (NHC), the center of the storm came ashore around 19:50 UTC (12:50 pm PDT) Wednesday May 29th about 35 km (~20 miles) west of Tonala, Mexico as a minimal Category 1 hurricane with maximum sustained winds of 75 mph. TRMM captured the first image of Barbara several hours after it made landfall. The image was taken at 6:46 pm PDT 29 May (01:46 UTC 30 May) 2013 and shows the horizontal distribution of rain intensity within the storm. Rain rates in the center of the swath

Three people died this past weekend from flooding in San Antonio, Texas. The TRMM satellite flew above Texas early Saturday morning at 1118 UTC (6:18 AM CDT) when powerful thunderstorms were drenching San Antonio. Data captured with this orbit by TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) were used in this rainfall analysis. TRMM's Precipitation Radar (PR) instrument found rain falling at a rate of over 66 mm/hr (~2.5 inches) in one violent thunderstorm shown near the center of this image. This 3-D image shows a TRMM Precipitation Radar (PR) slice through storms over Texas. One

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

Tropical cyclone Mahasen is moving through the Bay of Bengal and is predicted by the Joint Typhoon Warning Center to impact southeastern Bangladesh and northwestern Myanmar (Burma) in about 4 days. This analysis shows a TRMM Multisatellite Precipitation Analysis (TMPA) of rainfall that occurred with tropical cyclone Mahasen during the past week. So far rainfall from Mahasen has fallen mainly over the open waters of the northern Indian Ocean and the Bay Of Bengal. Rainfall totals of about 500mm (~19.7 inches) are shown east of Indonesia in this analysis. Click here to see a rainfall total

The TRMM satellite again flew almost directly above intensifying tropical cyclone Mahasen (01B) on May 11, 2013 at 2157 UTC. Rainfall data from TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) instruments are shown overlaid on an infrared image from the Visible and InfraRed Scanner (VIRS). TRMM PR data found that the heaviest rainfall was falling at a rate of over 142 mm/hr (~5.6 inches) in a band of powerful storms well to the southwest of Mahasen's center. At the time of this TRMM pass Mahasen's winds were estimated to be about 50kts (~58 mph). Mahasen's winds are predicted to

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
