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.
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.

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...
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...
