TRMM

On February 27, 2013 at 0559 UTC The TRMM satellite again saw tropical cyclone Rusty moving toward Australia's coastline north-west of Hedland. A rainfall analysis derived from TRMM's Microwave Imager (TMI) data is shown overlaid on a visible/infrared image from the TRMM Visible and InfraRed Scanner (VIRS). Rusty's eye, surrounded by light to moderate rainfall, was revealed by TRMM's TMI data to be located very near the coastline.

The TRMM satellite had an excellent view of tropical cyclone Evan on December 12, 2012 at 1704 UTC when it was battering the Samoan Islands with hurricane force winds. Evan is predicted by the Joint Typhoon Warning Center (JTWC) to intensify and have winds of 130kts (~150 mph) while remaining close to the islands. This wind speed would make it a strong Category 3 storm on the Saffir-Simpson Scale. A storm surge of 4.5 meters (14 feet) was reported along the Samoan coast. Evan's rainfall was analyzed using TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) data. This analysis shows that

Intensifying tropical cyclone Evan devastated the Samoan Islands when it passed over the islands on December 13, 2012. The TRMM satellite flew directly above Evan today (December 14, 2012) at 0659 UTC when the tropical cyclone was a category 3 on the Saffir-Simpson scale with winds of 100kts (115 mph). TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) data were used in the rainfall analysis on the first image. TRMM's Precipitation Radar (PR) showed that very intense storms in Evan's eye wall were dropping rain at a rate of up to 147mm/hr (~5.8 inches). The strongest radar reflectivity

After forming just south of the Solomon Islands on the evening of December 28th (local time), Cyclone Freda moved southward and intensified, becoming a strong Category 3 cyclone on the 30th. As the storm continued to move south, it weakened significantly and approached the island of New Caledonia on the 2nd of January 2013 as a tropical storm. TRMM captured this image of Freda at 07:16 UTC (6:16 pm local time) 2 January 2013. The image shows an instantaneous snap shot of the rain intensities within Freda. Rain intensities in the center of the swath are from the TRMM Precipitation Radar (PR)

A large area of low pressure from the remnants of tropical storm Oswald has caused additional extremely heavy rainfall as it moved southward over eastern Australia. This deluge has caused flooding in areas from the Cape York Peninsula to the Queensland state capital, Brisbane. At least four deaths have been attributed to the high winds and flooding associated with this low pressure system. This image shows a TRMM calibrated Multi-satellite Precipitation Analysis (MPA) for the period from January 21-28, 2013. This analysis shows that tropical cyclone Oswald dumped over 600mm (~23.6 inches) of

Despite it only being the end of January, a large spring-like storm system recently swept through the central and eastern part of the country, bringing a surge of warm air northward over the eastern third of the country and a threat for severe weather over much of the southeast as a strong jet stream dove down out of the Rockies southward to the northern Gulf Coast before racing northward again on the western side of the Appalachians. TRMM captured this image of a long line of strong storms associated with an advancing cold front stretching from southwest Alabama up through the central part of

At 1257 UTC (7:57 AM EST) this morning the TRMM satellite passed above a rapidly deepening low pressure center over coastal North Carolina. TRMM already saw stormy weather with this low when it was forming yesterday along the Gulf coast. Another area of low pressure moving from the Mid-West is predicted to merge with this storm and result in extreme blizzard conditions over the North-East. Near hurricane force winds and snowfall depths of over 610mm (~24 inches) are predicted in some areas from New York to Boston. An analysis of rainfall from TRMM's Microwave Imager (TMI) and Precipitation

As accurately predicted by the National Weather Service, a blizzard dropped extreme amounts of snow over the North-East beginning on February 8, 2013. An amazing snow depth of 38 inches (~965 mm) was reported in Milford, Connecticut. The blizzard was reportedly the cause of at least 14 deaths in the United States and Canada. The TRMM-based, near-real time Multi-satellite Precipitation Analysis (TMPA) at the NASA Goddard Space Flight Center is used to estimate precipitation for much of the globe. TMPA (liquid) precipitation totals (mm) are shown for the week from February 4-10 when the blizzard

The TRMM satellite had a good look at a tropical storm called Haruna forming in the Mozambique Channel on February 18, 2013 at 1541 UTC. Haruna was called a tropical storm early today and TRMM had another fairly good view when it flew above at 0811 UTC. Haruna is predicted to intensify to a strong tropical storm with wind speeds of about 50kts (~58 mph) and cross southern Madagascar in a couple days. TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) rainfall data were used in the two rainfall analyses shown. TRMM PR showed that very intense rain was falling at a rate of over 134 mm/hr

The TRMM satellite flew above intensifying tropical storm Haruna in the Mozambique Channel again on February 20, 2013 at 0717 UTC. A rainfall analysis using data from TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) instruments is shown overlaid on a combination visible/infrared image from the Visible and InfraRed Scanner (VIRS). TRMM showed that Haruna had become much better organized than yesterday with intense bands of rainfall circling the tropical cyclone's center of circulation. Some rain in powerful storms on the northern edge of Haruna's center was found by TRMM PR to be
