NASA sees Cyclone Giovanna enter the Mozambique Channel

16.02.2012
Cyclone Giovanna crossed over the island of Madagascar leaving flooding and damages in its wake and has now entered the Mozambique Channel. NASA's Aqua satellite captured an image that showed a ragged eye still exists, and the storm is regaining strength in the warm Channel waters.

Once Giovanna traversed the island nation of Madagascar and entered the Mozambique Channel, the body of water between Madagascar and Mozambique on the African mainland, NASA's Aqua satellite passed overhead and captured a visible image with the Moderate Resolution Imaging Spectroradiometer (MODIS) instrument.

MODIS captured the image at 10:45 UTC (5:45 a.m. EST) on February 15. The image showed that convection (rising air that forms the thunderstorms that make up the storm) had diminished greatly in the northwestern quadrant of the storm,. The MODIS image also showed that thunderstorms were now building around the rest of the tropical storm as a result ove moving into the warm waters of the Mozambique Channel. Sea surface temperatures of at least 80 Fahrenheit (26.6 Celsius) are needed to maintain a tropical cyclone, and temperatures in the Channel are as warm as ~88 Fahrenheit (31 Celsius).

On February 15, 2012 at 0300 UTC (Feb. 14 at 10 p.m. EST), Tropical Storm Giovanna's maximum sustained winds were near 40 knots (46 mph/74 kph). Tropical Cyclone Giovanna's center was located approximately 250 nautical miles west-southwest of Antananarivo, Madagascar, near 20.8 South and 42.4 East. It is moving to the west-southwest at 13 knots (15 mph/24 kph).

BBC News reports that at least two people died from storm related incidents, and the town Vatomandry, south of where Giovanna made landfall in east-central Madagascar, has experienced a lot of damage. BBC News reports that at least 60 percent of homes in the town were damaged or destroyed. Trees, phone and power lines have been downed, especially in eastern areas, as recovery efforts continue.

The Joint Typhoon Warning Center uses satellite data and forecast computer models to create forecasts. The current forecast for Giovanna now takes it on a westerly track toward Mozambique by the week's end. The forecast also indicates that wind shear will increase, which will prevent the storm from strengthening further. Residents along the southeastern coast of Mozambique should monitor the path of this tropical storm.

Im Focus: New Method of Characterizing Graphene

Scientists have developed a new method of characterizing graphene’s properties without applying disruptive electrical contacts, allowing them to investigate both the resistance and quantum capacitance of graphene and other two-dimensional materials. Researchers from the Swiss Nanoscience Institute and the University of Basel’s Department of Physics reported their findings in the journal Physical Review Applied.

Graphene consists of a single layer of carbon atoms. It is transparent, harder than diamond and stronger than steel, yet flexible, and a significantly better...

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...
