NASA sees Tropical Storm Alenga intensifying

08.12.2011
NASA's TRMM satellite passed over Tropical Storm Alenga and noticed that the rainfall has intensified in the storm in the last two days indicating that it continues strengthening.

The Tropical Rainfall Measuring Mission satellite called TRMM again passed over intensifying tropical storm Alenga in the South Indian Ocean on December 5, 2011 at 2103 UTC (6:03 p.m. EST). As expected, Alenga had become better organized with TRMM's Precipitation Radar (PR) seeing scattered bands of heavy rainfall spiraling into the center of the storm.

A 3-D image using TRMM PR was created at NASA's Goddard Space Flight Center in Greenbelt, Md. Very powerful storms were seen in the 3-D image. Some of those powerful thunderstorms reached heights of about 16 km (~9.9 miles). TRMM PR also found a reflectivity value of 53.67 dBZ which is an another indication that very heavy rainfall was occurring in those storms.

On Dec. 7, 2011 at 0600 UTC (1 a.m. EST), Tropical Storm Alenga's maximum sustained winds were up to 55 knots (63 mph/102 kmh)from 45 knots (52 mph/83 kmh)a day ago. Alenga was still safely at sea and far from land. The center of Alenga was located about 415 nautical miles west-southwest of the Cocos Islands near 14.5 South latitude and 90.2 East longitude. Alenga was moving to the east-southeast near 15 knots (17 mph/28 kmh).

On Dec. 7, satellite imagery showed improved banding of thunderstorms around the low-level center of the cyclone. The strongest bands of thunderstorms were on the northern side of Alenga's center.

Tropical Storm Alenga is forecast to keep strengthening because of warm sea surface temperatures and low wind shear. Alenga may reach hurricane-force over the next day or two before encountering strong westerly wind shear and weakening.

Im Focus: Strathclyde-led research develops world's highest gain high-power laser amplifier

The world's highest gain high power laser amplifier - by many orders of magnitude - has been developed in research led at the University of Strathclyde.

The researchers demonstrated the feasibility of using plasma to amplify short laser pulses of picojoule-level energy up to 100 millijoules, which is a 'gain'...

Im Focus: Can the immune system be boosted against Staphylococcus aureus by delivery of messenger RNA?

Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.

Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....

Im Focus: A quantum walk of photons

Physicists from the University of Würzburg are capable of generating identical looking single light particles at the push of a button. Two new studies now demonstrate the potential this method holds.

The quantum computer has fuelled the imagination of scientists for decades: It is based on fundamentally different phenomena than a conventional computer....

Im Focus: Turmoil in sluggish electrons’ existence

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.

We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...

Im Focus: Wafer-thin Magnetic Materials Developed for Future Quantum Technologies

Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.

Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
