NASA Satellite Tracks Tropical Cyclone Lehar Moving Toward India

27.11.2013
Tropical cyclone Lehar, located in the Bay of Bengal, continues to gain intensity while heading toward the same area of India where a much weaker tropical cyclone Helen recently came ashore. NASA's TRMM satellite passed over Lehar and measured rainfall and cloud heights to give scientists an understanding of how the storm is behaving.

NASA's Tropical Rainfall Measuring Mission satellite called TRMM flew above tropical cyclone Lehar on November 26, 2013 at 0307 UTC/Nov. 25 at 10:07 p.m. EST and captured rainfall data. Rainfall rates occurring in the storm were derived from TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) instruments.


On Nov. 26, 2013. NASA's TRMM satellite saw that rain was falling at a rate greater than 64 mm/~2.5 inches per hour in Lehar's center and in a band of intense rain wrapping around Lehar's northwestern side.

That data was taken and overlaid on an enhanced visible/infrared image from TRMM's Visible and InfraRed Scanner (VIRS) at NASA's Goddard Space Flight Center in Greenbelt, Md. to create a total picture of rainfall within the tropical cyclone. The TRMM instruments found that rain was falling at a rate greater than 64 mm/~2.5 inches per hour in Lehar's center and in a band of intense rain wrapping around Lehar's northwestern side. Some strong thunderstorms within Lehar were reaching heights above 15.25 km/~9.5 miles.

Warnings are already in effect in India. Northern Andhra Pradesh and southern Odisha are expected to feel Lehar's effects on Wednesday, November 27, when winds are expected to reach up to 91.7 knots/105.6 mph/170 kph.

At 1500 UTC/10 a.m. EST on November 26, Tropical Cyclone Lehar's maximum sustained winds were near 75 knots/86.1 mph/138.9 kph. Tropical-storm-force winds extend up to 100 nautical miles/115.1 miles/185.2 km from the center of the storm or 200 miles/230.2 miles/370.5 km in diameter. Lehar's center was located about 471 nautical miles southeast of Visakhapatnam, India, near 12.9 north and 88.6 east. Lehar was moving to the west-northwest at 9 knots/10.3 mph/16.6 km.

The Joint Typhoon Warning Center or JTWC predicts that Lehar's sustained wind speeds will reach 95 knots/~109 mph on November 27, 2013 and then decrease to about 85 knots/~98 mph before hitting India's east-central coast.

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: Tracing down linear ubiquitination

Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.

Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

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.
