System 92B appears to have weakened in the last day as an infrared look at the tropical low pressure area's cloud temperatures have shown. NASA's AIRS instrument is an infrared "eye in the sky" that recently flew over the weaker tropical low pressure area.
On May 22 at 19:29 UTC/3:29 p.m. EDT, NASA's Aqua satellite passed over System 92B and infrared data from the Atmospheric Infrared Sounder (AIRS) instrument and the SSMIS instrument saw patchy deep convection flaring and dissipating over the western portion of a low-level circulation center. Earlier on May 22, the areas of strong thunderstorms were more persistent west of the center of circulation.
On May 22 at 19:29 UTC/3:29 p.m. EDT, NASA's Aqua satellite passed over System 92B and the AIRS instrument saw that the strong thunderstorms over the western quadrant had weakened.

The Special Sensor Microwave Imager (SSM/I) and the Special Sensor Microwave Imager Sounder (SSMIS) are satellite passive microwave radiometers. This series of instruments has been carried onboard Defense Meteorological Satellite Program satellites since 1987.
The Joint Typhoon Warning Center (JTWC) noted that System 92B has weakened in response to persistent easterly vertical wind shear. The JTWC expects that wind shear to continue for another day.
On May 23 at 02:30 UTC (May 22 at 10:30 p.m. EDT), the center of System 92B was located near 16.2 north latitude and 91.0 east longitude, about 370 nautical miles south of Chittagong, Bangladesh. Maximum sustained winds are between 20 and 25 knots, and minimum central pressure is near 1002 millibars.
JTWC noted "based on the observed weakening trend and considering the potential for redevelopment if vertical wind shear relaxes over the next few days, the potential for the development of a significant tropical cyclone within the next 24 hours is downgraded to medium."

The IPH presents a solution at HANNOVER MESSE 2015 to make ship traffic more reliable while decreasing the maintenance costs at the same time. In cooperation with project partners, the research institute from Hannover, Germany, has developed a sensor system which continuously monitors the condition of the marine gearbox, thus preventing breakdowns. Special feature: the monitoring system works wirelessly and energy-autonomously. The required electrical power is generated where it is needed – directly at the sensor.
As well as cars need to be certified regularly (in Germany by the TÜV – Technical Inspection Association), ships need to be inspected – if the powertrain stops...
When an earthquake hits, the faster first responders can get to an impacted area, the more likely infrastructure--and lives--can be saved.
The Atlantic overturning is one of Earth’s most important heat transport systems, pumping warm water northwards and cold water southwards. Also known as the Gulf Stream system, it is responsible for the mild climate in northwestern Europe.
Scientists now found evidence for a slowdown of the overturning – multiple lines of observation suggest that in recent decades, the current system has been...
Because they are regularly subjected to heavy vehicle traffic, emissions, moisture and salt, above- and underground parking garages, as well as bridges, frequently experience large areas of corrosion. Most inspection systems to date have only been capable of inspecting smaller surface areas.
From April 13 to April 17 at the Hannover Messe (hall 2, exhibit booth C16), engineers from the Fraunhofer Institute for Nondestructive Testing IZFP will be...
