NASA sees a Tropical Storm Haliba 'sandwich'

11.03.2015

Tropical Storm Haliba appeared to be the "filling" in a sandwich between the Southern Indian Ocean islands of La Reunion and Mauritius in NASA satellite imagery because wind shear pushed the bulk of the storm's clouds between the islands.

NASA and the Japan Aerospace Exploration Agency's Tropical Rainfall Measuring Mission or TRMM satellite passed above Tropical Storm Haliba on March 9 when its center was just west of La Reunion Island at 1035 UTC (6:25 a.m. EDT).


RapidScat measurements between March 9 from 22:17 to 23:49 UTC revealed Haliba's sustained winds dropped to 34 mph/55 kph) near the center and southern quadrant of the storm.

The bulk of precipitation appeared east of the center of Haliba's circulation making it appears as if the storm was between Reunion and Mauritius (which is northeast of Reunion). Westerly vertical wind shear was pushing the clouds and showers east of the center.

TRMM's Precipitation Radar (PR) instrument indicated that the heaviest rainfall of over 181 mm (7.1 inches) per hour was located in an intense rain band located northeast of Reunion Island.

TRMM's Precipitation Radar (PR) data showed the most powerful storms in this band of thunderstorms were reaching heights above 16.8 km (10.4 miles). Radar reflectivity values of 55.5 dBZ returned from heavy rainfall in that area are another proof of rainfall intensity in that area.

The International Space Station's RapidScat instrument captured a look at Tropical Cyclone Haliba's surface winds. RapidScat measured the winds later on March 9 from 22:17 to 23:49 UTC. By that time, Haliba had weakened.

Measurements revealed that sustained winds at the surface were as high as 15 meters per second (34 mph/55 kph) near the center and southern quadrant of the storm, indicating that the storm had dropped below tropical storm status and weakened to a depression.

By 0900 UTC on March 10, Tropical Cyclone Haliba's maximum sustained winds remained near 30 knots (34 mph/55 kph). It was centered near 23.7 south latitude and 55.3 east longitude, about 192 nautical miles (221 miles/356 km) south of St. Denis, La Reunion.

Tropical Depression Haliba was moving to the south-southwest at 8 knots (9.2 mph/14.8 kph).

The westerly vertical wind shear that affected Haliba on March 9 continued on March 10 and weakened the storm to a depression. The Joint Typhoon Warning Center expects the storm to maintain its strength over the next day until it dissipates.

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...
