2 NASA satellites analyze Hurricane Humberto's clouds and rainfall

12.09.2013
Two NASA satellites passed over the hurricane in the Eastern Atlantic on Sept. 10 gathering information about the environment of Hurricane Humberto.

NASA's Aqua satellite gathered infrared and visible data on Humberto's clouds while NASA's TRMM satellite measured the rainfall rates occurring from those clouds. Humberto is the first hurricane of the Atlantic Ocean hurricane season.

NASA's Tropical Rainfall Measuring Mission satellite called TRMM had an excellent daytime view of strong Humberto on September 10 at 1636 UTC/12:36 p.m. EDT. At NASA's Goddard Space Flight Center in Greenbelt, Md. rainfall derived from TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) data were overlaid on a combination visible/infrared image from TRMM's Visible and InfraRed Scanner (VIRS) to provide a picture of rainfall rates within the storm.

TRMM PR found that the heaviest rainfall associated with Humberto was not near the center of circulation but in convective storms west of the storm. TRMM saw rainfall rates of up to 2 inches/50 mm per hour in the large band of thunderstorms west of Humberto's center. At that time, Humberto was a tropical storm with highest winds near 55 knots (~63 mph).

NASA's Aqua satellite passed over Hurricane Humberto and analyzed the storm in infrared light using the Atmospheric Infrared Sounder known as AIRS and visible light using the MODIS instrument. AIRS gathered data on Sept. 11 at 03:29 UTC/Sept. 10 at 11:29 p.m. EDT and revealed cloud cloud-top temperatures in excess of -63F/-52C in thunderstorms around the hurricane's center of circulation and in bands of thunderstorms west of the center. The MODIS or Moderate Resolution Imaging Spectroradiometer instrument showed a thick band of thunderstorms wrapping into the center from the west.

At 11 a.m. EDT on Sept. 11, Hurricane Humberto made a turn to the north and is expected to continue in that direction for another day or two. It was centered about 340 miles/550 km west of the Cape Verde Islands, near 16.7 north and 29.1 west. Humberto has maximum sustained winds near 80 mph/130 kph and is moving to the north near 9 mph/15 kph.

The National Hurricane Center noted that Humberto could strengthen a little today before weakening on Sept. 12. Humberto is headed for cooler waters and an environment where wind shear is expected to increase which is why it is expected to weaken.

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.
