An Infrared NASA Eye Sees a Weaker System 92B


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."

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...
