NASA sees heavy rain continue in Tropical Cyclone Amara

20.12.2013
NASA's TRMM satellite saw heavy rainfall was happening in Tropical Cyclone Amara on December 16, and still occurring on December 19, although it moved from east to southeast. Warnings are already in effect for Mauritius' Rodrigues Island.

NASA's Tropical Rainfall Measuring Mission or TRMM satellite can measure rainfall rates from space, and that's what it has been doing over Tropical Cyclone Amara since it was born. On Dec. 16, at 2043 UTC/3:43 p.m. EST TRMM data showed scattered bands of moderate to heavy rain falling at a rate of over 76.9 mm/3 inches per hour spiraling into Amara's center. Cloud tops reached 13 km/8 miles high near the center and eastern side.

On Dec. 19 at 0441 UTC, the Naval Research Laboratory in Washington, D.C. combined TRMM satellite rainfall data with a visible image of Amara's clouds from Japan's METEO-7 satellite to provide a complete picture of the storm. The image revealed that the heaviest rain was falling southeast of the center at 1.6 inches/40 mm per hour.

By 0900 UTC/4 a.m. EST, Tropical Cyclone Amara's maximum sustained winds were near 105 knots/120.8 mph/194.5 kph, making it hurricane-strength. Amara was still about 740 nautical miles east-northeast of La Reunion Island, centered near 17.2 south latitude and 68.3 east longitude.

Amara does, however, threaten Rodrigues Island. The Mauritius Meteorological Service or MMS has already put a cyclone class 2 warning in effect for Rodrigues Island. The island is part of the Republic of Mauritius and is located about 350 miles/560 kilometers east of Mauritius.

Amara was moving to the west-southwest at 9 knots and over the next several days is expected to take a more southern route. Occasional showers from Tropical Cyclone Amara are likely on Dec. 20 at night (local time) and will become more frequent, according to the MMS. MMS warns that sustained winds can be expected between 18.6 to 24.8 mph / 30 to 40 kph with gusts to 68.3 mph/75 kph. Amara is also expected to generate rough seas and ocean swells. Maximum significant wave heights can reach 9.1 meters/30 feet.

Amara was moving to the west-southwestward at 9 knots/10.3 mph/16.6 kph. The Joint Typhoon Warning Center expects Amara to continue moving slowly west-southwestward while it remains in a weak steering environment, moving between two deep layer subtropical ridges (elongated areas of high pressure).

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.
