NASA Watches a Gulf Weather System for Unusual Subtropical Development

07.02.2012
Hurricane season in the Atlantic Ocean and Gulf of Mexico doesn't begin until June 1, 2012, but a low pressure area in the Gulf called System 90L, is being watched on February 5 and 6 for possible development into sub-tropical depression although the chances are now slim to none. Data from the GOES-13 satellite was created into an image at NASA, and it showed System 90L raining on south Florida today.

On Sunday, February 5, at 6:45 p.m. EST the National Hurricane Center (NHC) issued a special tropical weather outlook for System 90L. The outlook stated, "A non-tropical low pressure system interacting with an upper-level trough (elongated area of low pressure) is producing widespread cloudiness...showers...and scattered thunderstorms across much of western and central Cuba...the lower Florida keys...and adjacent waters of the northwestern Caribbean Sea...southeastern Gulf of Mexico...and the Florida Straits." At that time, System 90L was located just west of Cuba's western tip and the NHC gave it a 30 percent chance of becoming a subtropical cyclone.

By Monday, February 6 at 7 a.m. EST, System 90L extended from western Cuba northward into the Florida straits and it was interacting with a mid-to-upper-level trough (elongated area of low pressure). Because there are no signs of organized surface circulation, the NHC has dropped the chance that the system will develop into a subtropical depression to near zero.

NOAA's GOES-13 satellite captured a visible image of System 90L in the eastern Gulf of Mexico on Monday, February 6, 2012. The image was created by NASA's GOES Project at the NASA Goddard Space Flight Center in Greenbelt, Md. NOAA operates the GOES series of satellites, and NASA's GOES Project creates imagery and animations from the satellite data. In the image, System 90L appeared as the somewhat rounded area of clouds over Florida's southern peninsula. Some of the thunderstorms in the northwestern quadrant of System 90L appeared to be higher (they cast shadows on the clouds around them) and were likely stronger with heavy rain.

Even though the chance for development into a pre-season subtropical storm is now near zero, System 90L is expected to bring widespread heavy rainfall and some gusty winds over northern Cuba, the Florida Keys and south Florida on Monday, February 6. The National Weather Service issued a hazardous weather outlook on February 6 for Miami that calls for locally heavy rain with a slight risk of thunderstorms. Thunderstorms may contain gusty winds and occasional lightning strikes. There is also a slight risk of rip currents at the Palm Beach County beaches on Florida's east coast.

System 90L is moving to the northeast at about 15 mph and is creating a very wet start to the week in southern Florida.

Im Focus: Interfacial Superconductivity: Magnetic and superconducting order revealed simultaneously

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.

While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Laser-driving of semimetals allows creating novel quasiparticle states within condensed matter systems and switching between different states on ultrafast time scales

Studying properties of fundamental particles in condensed matter systems is a promising approach to quantum field theory. Quasiparticles offer the opportunity...

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...
