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: Can we see monkeys from space? Emerging technologies to map biodiversity

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.

Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...

Im Focus: Climate satellite: Tracking methane with robust laser technology

Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.

Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...

Im Focus: How protons move through a fuel cell

Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.

As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...

Im Focus: A unique data centre for cosmological simulations

Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.

With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
