NASA's TRMM satellite sees birth of Arabian Sea cyclone

25.10.2012
NASA's TRMM satellite measured rainfall and towering clouds within the Arabian Sea's first tropical cyclone of the season as it passed overhead from space. Meanwhile, the infrared AIRS instrument aboard NASA's Aqua satellite noticed that strong thunderstorms surrounded the center of the storm. Tropical Cyclone 1A is expected to be short-lived as it heads for a landfall in Somalia on Oct. 25.

Since it was launched in 1997 the Tropical Rainfall Measuring Mission (TRMM) satellite has been useful for monitoring tropical cyclones in the tropics. TRMM passed above the first tropical cyclone of 2012 (TC01A) as it was forming in the Arabian Sea on October 2012 at 1513 UTC (11:13 a.m. EDT). Rainfall from TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) were overlaid on an enhanced infrared image from TRMM's Visible and InfraRed Scanner (VIRS) to provide a complete picture of rainfall rates occurring within the storm.


TRMM passed above the first tropical cyclone of 2012 as it was forming in the Arabian Sea on October 2012 at 11:13 a.m. EDT. TRMM saw that rain at the surface was falling at a rate of up to 41 mm/hour (~1.6 inches) and thunderstorms within were reaching heights of over 16 km (~9.9 miles).

TRMM PR and TMI data showed that rain at the surface was falling at a rate of up to 41 mm/hour (~1.6 inches) in the forming tropical cyclone. Bands of thunderstorms were also wrapping tightly into a well-defined low level center of circulation. TRMM PR data also was also used to create a 3-D image that showed the vertical structure of convective storms in the area. The view showed some towering convective storms were reaching heights of over 16 km (~9.9 miles).

Another satellite passed over TC01A and captured infrared data on the storm, revealing temperature of cloud tops. The colder the cloud top, the higher the thunderstorm is in the atmosphere, and the more powerful the storm. The Atmospheric Infrared Sounder (AIRS) instrument aboard NASA's Aqua satellite captured infrared imagery of Tropical Storm 01A on Oct. 24 at 5:35 a.m. EDT (0935 UTC) that showed the strongest thunderstorms surrounded the center of circulation. Those thunderstorms were reaching high into the troposphere where cloud top temperatures are as cold as -63 Fahrenheit (-52 Celsius).

On Oct. 24 at 1500 UTC (11 a.m. EDT), TC01A had maximum sustained winds near 35 knots (~40 mph). It was located about 300 nautical miles east-southeast of Cape Guardafui, Somalia, near 10.4 North latitude and 55.7 East longitude. TC01A was moving to the west at 16 knots and is expected to move to the west-southwest over the next couple of days before making landfall south of Cape Guardafui, Somalia. Cape Guardafui is located in the northeastern Bari province and forms the geographical point of the Horn of Africa.

Tropical cyclone 01A is predicted by the U.S. Navy Joint Typhoon Warning Center (JTWC) to hit northeastern Somalia on October 25, 2012 with wind speeds of about 35 knots (~40 mph).

Im Focus: Giant Magnetic Fields in the Universe

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.

The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...

Im Focus: Polymer-coated silicon nanosheets as alternative to graphene: A perfect team for nanoelectronics

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Im Focus: Researchers Imitate Molecular Crowding in Cells

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
