NASA watching 2 areas in the Caribbean, 1 is a rainmaker

06.06.2011
Keeping an eye out for tropical cyclone development

There are two low pressure areas in the Caribbean Sea for future development into tropical cyclones, although the chances are near zero for one, and minimal for the other. The GOES-13 satellite has been following the life of System 93L, which is one of those systems. The second low pressure area may not develop over the weekend, but threatens heavy rain in Hispaniola, Cuba and Jamaica.

The GOES-13 satellite provides images of the U.S. east coast, Atlantic and Caribbean Sea continually every day. In an image from 1731 UTC (1:31 p.m. EDT) today, June 3, the low pressure area known as System 93L is located in the far western Caribbean Sea. It appears as a small area of cloudiness, about 275 miles east-southeast of Brownsville, Texas. GOES-13 has been tracking that low pressure area for over a week, since it developed off the North Carolina coast and tracked across Florida last weekend and into the Gulf of Mexico.

Wind shear will continue to prevent System 93L from developing further over the weekend, so there's a "near zero percent chance" it will develop in the next 48 hours, according to the National Hurricane Center. System 93L now appears to be moving northwestward between 10 and 15 mph after tracking southward earlier this week.

A second low pressure area is also catching the eye of forecasters who use GOES-13 satellite data. The second low is located a couple hundred miles south of Jamaica and has become a little better defined today. That low pressure area appears to dwarf System 93L in size, as the center of circulation is surrounded by a large area of cloudiness.

One factor that keeps that low's chance for development down to 20% this weekend is the movement of dry air into its western side. Dry air prevents formation of the thunderstorms that power a tropical cyclone.

Despite the low chances for development, however, this low is expected to bring heavy rainfall, flash flooding and mudslides over portions of Jamaica, Haiti, the Dominican Republic and southeastern Cuba over the next couple of days. That low is forecast to remain almost stationary over the west-central Caribbean Sea for the next couple of days.

The image of both low pressure areas was created by the NASA/NOAA GOES Project at NASA's Goddard Space Flight Center in Greenbelt, Md. The series of Geostationary Operational Environmental Satellites (GOES) are managed by NOAA, and the NASA/NOAA GOES Project creates images and animations from those satellites.

Im Focus: Scientists present new observations to understand the phase transition in quantum chromodynamics

The building blocks of matter in our universe were formed in the first 10 microseconds of its existence, according to the currently accepted scientific picture. After the Big Bang about 13.7 billion years ago, matter consisted mainly of quarks and gluons, two types of elementary particles whose interactions are governed by quantum chromodynamics (QCD), the theory of strong interaction. In the early universe, these particles moved (nearly) freely in a quark-gluon plasma.

This is a joint press release of University Muenster and Heidelberg as well as the GSI Helmholtzzentrum für Schwerionenforschung in Darmstadt.

Then, in a phase transition, they combined and formed hadrons, among them the building blocks of atomic nuclei, protons and neutrons. In the current issue of...

Im Focus: Patented nanostructure for solar cells: Rough optics, smooth surface

Thin-film solar cells made of crystalline silicon are inexpensive and achieve efficiencies of a good 14 percent. However, they could do even better if their shiny surfaces reflected less light. A team led by Prof. Christiane Becker from the Helmholtz-Zentrum Berlin (HZB) has now patented a sophisticated new solution to this problem.

"It is not enough simply to bring more light into the cell," says Christiane Becker. Such surface structures can even ultimately reduce the efficiency by...

Im Focus: New soft coral species discovered in Panama

A study in the journal Bulletin of Marine Science describes a new, blood-red species of octocoral found in Panama. The species in the genus Thesea was discovered in the threatened low-light reef environment on Hannibal Bank, 60 kilometers off mainland Pacific Panama, by researchers at the Smithsonian Tropical Research Institute in Panama (STRI) and the Centro de Investigación en Ciencias del Mar y Limnología (CIMAR) at the University of Costa Rica.

Scientists established the new species, Thesea dalioi, by comparing its physical traits, such as branch thickness and the bright red colony color, with the...
