Two NASA Satellites See System 92B Headed North in Bay of Bengal

23.05.2014

NASA's Aqua and TRMM satellites captured radar and infrared data on developing tropical low pressure area System 92B as it now makes it way north through the Bay of Bengal.

On May 22 at 00:51 UTC, NASA and the Japan Aerospace Exploration Agency's Tropical Rainfall Measuring Mission (TRMM) satellite passed over System 92B as it was dropping heavy rainfall over the Bay of Bengal.


In this TRMM 3-D image of System 92B from May 21, some powerful convective storm tops were reaching heights of almost 17 km (about 10.5 miles).

TRMM's Precipitation Radar (PR) revealed that rain was falling at the extreme rate of over 191 mm (about 7.5 inches) per hour in powerful convective storms in the center of the Bay of Bengal well to the east of India.

At NASA's Goddard Space Flight Center in Greenbelt, Maryland, TRMM's Precipitation Radar data were also used to construct a simulated 3-D view of 92B's rainfall structure looking toward the east from India.

TRMM PR pulled away a veil of clouds and revealed that some powerful convective storm tops were reaching heights of almost 17 km (about 10.5 miles). The extreme rainfall in this area was returning radar reflectivity values of over 53.7 dBZ to the TRMM satellite.

On May 22 at 7:11 UTC/3:11 a.m. EDT, NASA's Aqua satellite passed over System 92B and the Atmospheric Infrared Sounder or AIRS instrument captured infrared data on the low's cloud tops. Satellite imagery shows that the low-level circulation center is large and poorly defined with flaring and fragmented deep convection.

The data showed two areas where thunderstorms had high cloud tops and very cold temperatures near -63F/-52C. Thunderstorms that high into the troposphere have been found to generate heavy rainfall. The areas of strong thunderstorms were north and west of the center of circulation.

By 08:00 UTC/4 a.m. EDT, the Joint Typhoon Warning Center estimated that System 92B had maximum sustained winds between 25 to 30 knots (28.7 to 34.5 mph/46.3 to 55.5 kph). Metsat satellite imagery indicated that the circulation center is located near 17.0 north latitude and 92.1 east longitude in the Bay of Bengal, about 315 nautical miles south of Chittagong, Bangladesh.

System 92B is moving north at 5 knots (5.7 mph/9.2 kph). Computer models vary on the development of the tropical low pressure area, but do expect it to continue drifting to the north and north-northwest.

The Joint Typhoon Warning Center noted that System 92B's potential for the development of a significant tropical cyclone within the next 24 hours remains high.

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

Im Focus: Fraunhofer ISE Develops Highly Compact, High Frequency DC/DC Converter for Aviation

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.

Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
