Cyclone Nathan Circles Back

Cross-Calibration team (PMM)
Cyclone Nathan located in the Coral Sea off Australia's Queensland coast has made another loop and is again headed slowly toward the Cape York Peninsula. Rainfall derived from the TRMM satellite's Microwave Imager (TMI) and Precipitation Radar (PR) instruments is shown with data collected on March 18, 2015 at 0758 UTC. The heaviest rainfall was measured by TRMM PR falling at a rate of over 119 mm (4.7 inches) on the eastern side of Nathan's eye. TRMM PR data were used in this 3-D view of cyclone Nathan. Storm heights in a rain band circling Nathan's northwestern side were found reaching

Cyclone Pam Departs Vanuatu

http://pmm.nasa.gov/meetings/watershed-science-summer-institute#
As one of the strongest cyclones every recorded in the South Pacific, Cyclone Pam devastated the island archipelago of Vanuatu. As the cyclone bore down on Vanuatu's central islands on the afternoon (local time) of March 13th, Pam's maximum sustained winds were estimated to have increased to 270 kph (~167 mph) by the US Joint Typhoon Warning Center (JTWC), making it a category 5 storm on the US Saffir-Simpson scale. The storm caused immense, widespread damage with the islands of Erromango and Tanna suffering a direct hit. Although damage is still being assessed, the number of reported

Tropical Cyclone Eunice

Tropical Cyclone Eunice
Tropical cyclone Eunice became the fourth tropical cyclone of the 2015 Southern Indian Ocean season when it formed well east of Madagascar on January 27, 2014. Maximum sustained winds within the tropical cyclone have increased to about 85kts (~98 mph) and Eunice is predicted by the Joint Typhoon Warning Center (JTWC) to continue becoming more powerful as it travels toward the southeast. The GPM (core satellite) flew directly over the eye of newly formed tropical cyclone on January 28, 2015 at 1049 UTC. GPM's Microwave Imager (GMI) found that rain was falling at a rate of only 30.2 mm (about 1

GPM Sees Heavy Snow Over New England

Signs of Spring Spring Weather What is spring to you? Spring around the world March 20 - launch of contest
Wednesday, January 28, 2015
At 5:05 p.m. EST Monday, Jan. 26, 2015, the Global Precipitation Measurement mission's Core Observatory flew over the Nor'easter that dumped snow on New England. This satellite image shows the rate of rainfall, with low amounts in green and high in red, and snowfall, in blue to purple. The center of the storm, shown in 3-D, was offshore with far reaching bands of snowfall. More intense snow rates are shown in darker blue, which can be seen on the northern edge of the storm. Visible in the 3-D image of the center of the storm are the snowy tops of the clouds in blue and underneath where it...

Mekkhala Becomes A Typhoon, Drenches The Philippines

Mekkhala Becomes A Typhoon, Drenches The Philippines
On January 16, 2015 tropical storm Mekkhala became the first western Pacific typhoon of the year just before hitting the eastern Philippines. This image shows rainfall derived from data captured by the GPM (core satellite) on January 16, 2015 at 2200 UTC. This was only about four hours after Mekkhala was upgraded to a typhoon. GPM's Microwave Imager (GMI) found rain falling at a rate of over 70.7 mm (about 2.8 inches) per hour in storms southwest of the typhoon's eye. Rainfall over the Philippines, enhanced by typhoon Mekkhala, was analyzed using near real time merged satellite data (3B42)

Southwest Indian Ocean Has Two Tropical Cyclones

Southeast Indian Ocean Has Two Tropical Cyclones
As tropical storm Mekkhala approaches the Philippines in the northern hemisphere tropical cyclone activity in the southeast Indian ocean has recently increased. The TRMM satellite has been monitoring rainfall in the tropics since 1997. On February 15, 2015 the TRMM satellite flew over two tropical cyclones in successive orbits. BANSI 1/15/2015 1308Z CHEDZA 1/15/2015 1440Z Rainfall derived from TRMM's Microwave Imager (TMI) is shown overlaid on a METEOSAT-7 Visble/Infrared images. On January 15, 2015 at 1308 UTC the satellite saw powerful category four tropical cyclone Bansi northeast of the

Tropical Depression Mekkhala Organizes

Tropical Depression Mekkhala Organizes
Tropical Depression 01W, in the western Pacific Ocean, has been given the name Mekkhala. The tropical cyclone has become much better organized and the Joint Typhoon Warning Center (JTWC) predicts that tropical storm Mekkhala will affect the eastern Philippines in a few days. The GPM (core satellite) flew above Mekkhala on January 14, 2015 at 1043 UTC. GPM's Microwave Imager (GMI) instrument observed rain falling at a rate of over 71.63 mm (about 2.8 inches) per hour in intense convective storms near the tropical cyclone's center. This 3-D view was derived from data collected by GPM's Radar (Ku

Two Satellites Measured Rainfall in Tropical Depression Mekkhala

Two Satellites Measured Rainfall in Tropical Depression Mekkhala
The first tropical depression of the 2015 western Pacific season formed southwest of Guam on January 13 and is predicted to intensify into a tropical storm while headed toward the Philippines. NASA's TRMM and GPM satellites provided a look at Tropical Depression Mekkhala's rainfall data that showed the area of moderate rainfall had expanded as the storm strengthened on January 13. Mekkhala was previously known as Tropical Depression 01W until January 14 when it was renamed. Both the Global Precipitation Measurement (GPM) core satellite and the Tropical Rainfall Measuring Mission (TRMM)

Deadly Flooding and Landslides With Tropical Storm Jangmi

Deadly Flooding and Landslides With Tropical Storm Jangmi
Jangmi became the 23rd named tropical cyclone in the western Pacific Ocean when it formed southeast of the Philippines on December 28, 2014. Heavy rainfall from Tropical storm Jangmi recently produced flooding and landslides in the Philippines that have reportedly killed over 30 people. The Philippines frequently gets hit by tropical cyclones. Tropical storm Jangmi hit only three weeks after slow moving typhoon Hagiput churned through the central Philippines. The TRMM satellite had a fairly good view of Jangmi on December 29, 2014 at 1425 UTC. The TRMM Microwave Imager(TMI) instrument showed
