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


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: Climate study finds evidence of global shift in the 1980s

Planet Earth experienced a global climate shift in the late 1980s on an unprecedented scale, fuelled by anthropogenic warming and a volcanic eruption, according to new research published this week.

Scientists say that a major step change, or ‘regime shift’, in the Earth’s biophysical systems, from the upper atmosphere to the depths of the ocean and from...

Im Focus: Lactate for Brain Energy

Nerve cells cover their high energy demand with glucose and lactate. Scientists of the University of Zurich now provide new support for this. They show for the first time in the intact mouse brain evidence for an exchange of lactate between different brain cells. With this study they were able to confirm a 20-year old hypothesis.

In comparison to other organs, the human brain has the highest energy requirements. The supply of energy for nerve cells and the particular role of lactic acid...

Im Focus: Laser process simulation available as app for first time

In laser material processing, the simulation of processes has made great strides over the past few years. Today, the software can predict relatively well what will happen on the workpiece. Unfortunately, it is also highly complex and requires a lot of computing time. Thanks to clever simplification, experts from Fraunhofer ILT are now able to offer the first-ever simulation software that calculates processes in real time and also runs on tablet computers and smartphones. The fast software enables users to do without expensive experiments and to find optimum process parameters even more effectively.

Before now, the reliable simulation of laser processes was a job for experts. Armed with sophisticated software packages and after many hours on computer...
