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: Ultrafast snapshots of relaxing electrons in solids

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!

When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...

Im Focus: Quantum Sensors Decipher Magnetic Ordering in a New Semiconducting Material

For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.

Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
