System 92L in Atlantic Getting Organized in a Tropical Way

15.06.2010
An area of low pressure referred to by meteorologists as "System 92L" in the Atlantic Ocean seems ripe for development and NASA infrared satellite imagery revealed areas in the low that have strong convection. Convection refers primarily to atmospheric motions in the vertical direction, or rising warm air that condenses and forms clouds.

NASA's Aqua satellite flew over the low pressure area on June 14 at 04:29 UTC (12:29 a.m. EDT). The Atmospheric Infrared Sounder (AIRS) instrument detects heat (and cold), and provides a great snapshot of the temperatures associated with the developing low and the ocean waters that lay in its path.

The low pressure area getting better organized and AIRS infrared imagery revealed there are some high, cold, strong thunderstorms in some of the areas of the low. AIRS data showed that some of the cloud tops are as cold, or colder than -74 Fahrenheit (- 58 Celsius and 215 Kelvin). AIRS also provided a look at the sea surface temperatures in the direction that System 92L is moving, and noticed they are about 80 degrees Fahrenheit or warmer (300 Kelvin or 27 Celsius) , warm enough to support tropical cyclone development.

At 8 a.m. EDT on June 14, System 92L was located about 1425 miles east-southeast of the Windward Islands. Looking at a map of the Atlantic, the low also sits far north of the eastern-most tip of Brazil. The center is difficult to determine but appears on NASA satellite imagery to be between 4 and 8 degrees North latitude and between 32 and 40 degrees West longitude.

The National Hurricane Center notes that "Environmental conditions are expected to remain conducive for development during the next day or so as the system moves west-northwestward to northwestward at about 15 mph. The low developed on Sunday, June 13 and was about 975 miles southwest of the southernmost Cape Verde Islands.

Because of favorable conditions for development, System 92L has a "high chance" for developing into a tropical depression, according to the National Hurricane Center. Forecasters there are giving 92L a "60 percent chance" of development in the next two days.

Meanwhile, in the Eastern Pacific Ocean, there are two areas that have small chances of development in the next 48 hours, but forecasters are keeping an eye on both of them.

The first area of cloudiness and showers are associated with a broad area of low pressure, that's about 350 miles west-southwest of Acapulco, Mexico. This low is poorly organized, although it may develop slowly. Currently the National Hurricane Center gives it a "20 percent chance" of developing in the next 48 hours. The second area lies near the Gulf of Tehuantepec and is also poorly organized. If this low develops, it is expected to occur slowly. This system also has a 20 percent chance of developing into a tropical depression in the next 48 hours.

Hurricane season has truly started. Forecasters now have lows in both the Atlantic and Eastern Pacific Ocean to keep an eye on this week.

Im Focus: Designing Architecture with Solar Building Envelopes

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.

As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...

Im Focus: How to inflate a hardened concrete shell with a weight of 80 t

At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).

Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...

Im Focus: Bacterial Pac Man molecule snaps at sugar

Many pathogens use certain sugar compounds from their host to help conceal themselves against the immune system. Scientists at the University of Bonn have now, in cooperation with researchers at the University of York in the United Kingdom, analyzed the dynamics of a bacterial molecule that is involved in this process. They demonstrate that the protein grabs onto the sugar molecule with a Pac Man-like chewing motion and holds it until it can be used. Their results could help design therapeutics that could make the protein poorer at grabbing and holding and hence compromise the pathogen in the host. The study has now been published in “Biophysical Journal”.

The cells of the mouth, nose and intestinal mucosa produce large quantities of a chemical called sialic acid. Many bacteria possess a special transport system...

Im Focus: Repairing defects in fiber-reinforced plastics more efficiently

Fiber-reinforced plastics (FRP) are frequently used in the aeronautic and automobile industry. However, the repair of workpieces made of these composite materials is often less profitable than exchanging the part. In order to increase the lifetime of FRP parts and to make them more eco-efficient, the Laser Zentrum Hannover e.V. (LZH) and the Apodius GmbH want to combine a new measuring device for fiber layer orientation with an innovative laser-based repair process.

Defects in FRP pieces may be production or operation-related. Whether or not repair is cost-effective depends on the geometry of the defective area, the tools...
