NASA Satellite Sees Fading Rainfall in Tropical Storm Nadine

20.09.2012
Tropical Storm Nadine continues to bring rains and winds to the Azores in the eastern Atlantic Ocean, but that rainfall continues to diminish according to data from NASA satellites. NASA's unmanned Global Hawk aircraft is also exploring the storm yesterday, Sept. 19.

A tropical storm warning is in effect on Sept. 19 for the islands of Flores, Corvo, Faial, Pico, Sao Jorge, Graciosa, Terceira, Sao Miguel and Santa Maria in the Azores.


NASA's TRMM captured Nadine's rainfall rates at 6:13 a.m. EDT on Sept. 19, and showed no rainfall was occurring near Nadine's center. Rainfall around Nadine's center was falling at 20mm~0.8 inches per hour. Nadine's past and predicted path with appropriate symbols is shown overlaid in white. (Credit: SSAI/NASA, Hal Pierce)

The Tropical Rainfall Measuring Mission (TRMM) satellite flew over Nadine on Sept. 19 at 1013 UTC (6:13 a.m. EDT) and captured data on rainfall rates occurring within the tropical storm. TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) data showed that no rainfall was occurring near Nadine's center. The maximum precipitation intensity found in rain bands around Nadine was only about 0.8 inches (20mm) per hour. The lack of convection (rising air that forms the thunderstorms that make up the tropical cyclone) is a sign that the tropical storm is decaying or weakening.

NASA's Hurricane Severe Storms Sentinel (HS3) Mission plans to send one of the unmanned Global Hawk aircraft to investigate Nadine again on Wednesday, Sept. 19.

On Sept. 19 at 11 a.m. EDT Tropical Storm Nadine's maximum sustained winds were near 50 mph (85 kmh). Nadine was located about 270 miles (430 km) west of the Azores islands, near 37.2 north latitude and 31.8 west longitude. Nadine is moving toward the north-northeast near 5 mph (7 kmh) and is expected to start drifting to the east-southeast. Nadine's estimated minimum central pressure was 993 millibars.

According to the National Hurricane Center, early on Sept. 19, Corvo in the Azores reported sustained winds of 42 mph (68 kmh) with a gust to 58 mph (93 kmh). In addition, ocean swells continue to affect the Azores and are causing life-threatening surf conditions and rip tides.

The National Hurricane Center noted that if Nadine continues to show weaker convection, it may no longer qualify as a tropical or subtropical cyclone.

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...
