NASA Caught Tropical Cyclone Hellen's Rainfall Near Peak

02.04.2014

When Tropical Cyclone Hellen was near the "peak of her career" NASA's TRMM satellite picked up on her popularity in terms of tropical rainfall. Hellen was a very heavy rainmaker in her heyday with heavy rain rates. Hellen weakened to a remnant low pressure area by April 1, but has now re-emerged in the Mozambique Channel.

Tropical Cyclone Hellen formed in the Mozambique Channel northwest of Madagascar on March 28, 2014. Hellen became a very powerful tropical cyclone with peak sustained winds of 130 knots/about 150 mph/241 kph on March 30, 2014. Hellen's eye came ashore in northwestern Madagascar on March 31 with winds predicted to be about 95 knots/109 mph/176 kph. 


On March 30, the TRMM satellite showed some powerful storms in Hellen's eye wall were reaching heights of over 13 km/8 miles.

NASA and the Japan Aerospace Exploration Agency's Tropical Rainfall Measuring Mission satellite known as TRMM passed above Hellen on March 30, 2014 at 17:47 UTC/1:47 p.m. EDT when the tropical cyclone was close to peak power.

A TRMM rainfall analysis that was derived from TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) data collected found that rain was falling at a rate of over 44 mm/1.7 inches per hour near the eye. Bands of moderate to heavy rain were shown moving over the northwestern coast of Madagascar.

TRMM PR data were collected at the same time in a swath that passed near the northern edge of tropical cyclone Hellen's eye wall. Those data were used to create a simulated 3-D view of Hellen's precipitation and also revealed that some powerful storms in Hellen's eye wall were reaching heights of over 13 km/8 miles.

Hellen seemed to run out of steam over Madagascar and the Joint Typhoon Warning Center issued the final warning on the tropical low pressure area on April 1 at 0300 UTC/March 31 at 11 p.m. EDT. AT that time, Hellen was centered near 17.0 south latitude and 46.1 east longitude, about 130 nautical miles/~150 miles/~241 km north-northwest of Antananarivo, Madagascar. Hellen was trudging to the south-southeast at 5 knots/5.7 mph/9.2 kph as it continued weakening. 

Thirty minutes after the last warning from the JTWC, Hellen's remnants had moved back over water in the Mozambique Channel. The JTWC noted that because of favorable conditions such as warm water and low wind shear, the storm could regenerate in the next couple of days.

Im Focus: Basel Physicists Develop Efficient Method of Signal Transmission from Nanocomponents

Physicists have developed an innovative method that could enable the efficient use of nanocomponents in electronic circuits. To achieve this, they have developed a layout in which a nanocomponent is connected to two electrical conductors, which uncouple the electrical signal in a highly efficient manner. The scientists at the Department of Physics and the Swiss Nanoscience Institute at the University of Basel have published their results in the scientific journal “Nature Communications” together with their colleagues from ETH Zurich.

Electronic components are becoming smaller and smaller. Components measuring just a few nanometers – the size of around ten atoms – are already being produced...

Im Focus: Into the ice – RV Polarstern opens the arctic season by setting course for Spitsbergen

On Tuesday, 19 May 2015 the research icebreaker Polarstern will leave its home port in Bremerhaven, setting a course for the Arctic. Led by Dr Ilka Peeken from the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI) a team of 53 researchers from 11 countries will investigate the effects of climate change in the Arctic, from the surface ice floes down to the seafloor.

RV Polarstern will enter the sea-ice zone north of Spitsbergen. Covering two shallow regions on their way to deeper waters, the scientists on board will focus...

Im Focus: Gel filled with nanosponges cleans up MRSA infections

Nanoengineers at the University of California, San Diego developed a gel filled with toxin-absorbing nanosponges that could lead to an effective treatment for skin and wound infections caused by MRSA (methicillin-resistant Staphylococcus aureus), an antibiotic-resistant bacteria. This "nanosponge-hydrogel" minimized the growth of skin lesions on mice infected with MRSA - without the use of antibiotics. The researchers recently published their findings online in Advanced Materials.

To make the nanosponge-hydrogel, the team mixed nanosponges, which are nanoparticles that absorb dangerous toxins produced by MRSA, E. coli and other...
