NASA satellites revealed Tropical Storm Ernesto's strongest side

08.08.2012
Satellite data helps forecasters see where the strongest part of a tropical cyclone is located, and NASA's Aqua satellite noticed Ernesto's strongest storms were on the eastern side yesterday. Today, strong storms surround Ernesto's center.

A visible image of Tropical Storm Ernesto approaching Central America was captured by the Moderate Resolution Imaging Spectroradiometer (MODIS) instrument that flies onboard NASA's Aqua satellite.


This visible image of Tropical Storm Ernesto was captured from NOAA's GOES-13 satellite on Aug. 7, 2012, at 1425 UTC (10:25 a.m. EDT) as it was approaching Belize and Mexico's Yucatan Peninsula. Although Ernesto does not yet have a visible eye on satellite imagery, it is expected to strengthen into a hurricane before landfall. *By 2 p.m. EDT, it strengthened into Hurricane Ernesto.*

In an image captured on August 6, 2012 at 1840 UTC (2:40 p.m. EDT), the strongest thunderstorms appeared to be on the northern and eastern sides of the storm. The area of strongest storms has expanded during the morning hours of August 7 and wrapped around the center of circulation as was visible in imagery captured by the GOES-13 satellite.

NOAA's GOES-13 satellite captured an image of Ernesto's clouds on August 7, 2012 at 1425 UTC (10:25 a.m. EDT) as it was approaching Belize and Mexico's Yucatan Peninsula. Although Ernesto does not yet have a visible eye on satellite imagery, it is expected to strengthen into a hurricane before landfall. The GOES-13 image did show more uniformity in the strength of thunderstorms that entirely surround Ernesto's center.

On August 7, warnings and watches are in effect in Central America as Ernesto approaches. A Hurricane Warning is in effect for Chetumal to Punta Allen on the east coast of the Yucatan peninsula the entire coast of Belize.

A Tropical Storm Warning is in effect for the coast of Honduras from the Honduras/Nicaragua Border westward to Punta Sal, including the Bay Islands. The Warning is also in effect from north of Punta Allen to Cancun on the east coast of the Yucatan Peninsula. The warning also extends to the Yucatan's west coast, from Celestun southward to Chilitepec along the west coast of the Yucatan.

The National Hurricane Center warned that Ernesto is expected to produce rainfall accumulations of 3 to 5 inches along the northern coast of honduras...with isolated amounts as high as 8 inches over mountainous terrain. Belize, the Yucatan Peninsula and northern Guatemala can expect between 4 and 8 inches with as much as a foot of rain in isolated areas, so flooding is expected and mudslides are possible.

A Tropical Storm Watch is in effect for the coast of Honduras from west of Punta Sal to the Honduras/Guatemala border.

At 8 a.m. EDT, Tropical Storm Ernesto's maximum sustained winds were near 65 mph (100 kmh) with higher gusts. The National Hurricane Center (NHC) expects Ernesto to strengthen into a hurricane before it makes landfall. The center of Tropical Storm Ernesto was located near latitude 17.8 north and longitude 84.4 west, about 250 miles (405 km) east of Belize City, Belize and about 180 miles (285 km) northeast of the island of Roatan, Honduras, where cruise ships are known to stop.

According to USA Today on-line, the Carnival Legend cruise ship is skipping stops near Belize and Honduras because of the tropical storm.

Ernesto is moving toward the west-northwest near 13 mph (20 kmh). The NHC expects Ernesto to keep moving to the west-northwest tonight and turn west on Wednesday, August 8, moving across the Yucatan Peninsula tonight and early Wednesday where it will emerge over the Bay of Campeche.

Watching Other Atlantic Lows

Meanwhile in the Atlantic Ocean, there are two other areas of low pressure that bear watching. One is a tropical wave located several hundred miles southwest of the Cape Verde Islands in the eastern Atlantic Ocean. The center is elongated, and the low is generating showers and thunderstorms. The NHC gives it a 20 percent chance for becoming a tropical depression in the next two days.

The second area was once Tropical Storm Florence and is now a remnant low pressure area. Showers have increased, but the atmospheric conditions are not conducive to strengthening. The remnants of post-tropical storm Florence are located about 1,000 miles east of the Northern Leeward Islands and the NHC gives it just a 10 percent chance of reforming.

ADDENDUM: Ernesto became a hurricane at 2 p.m. EDT, August 7, 2012, when maximum sustained winds reached 80 mph.

Im Focus: Nanoparticles help with malaria diagnosis – new rapid test in development

The WHO reports an estimated 429,000 malaria deaths each year. The disease mostly affects tropical and subtropical regions and in particular the African continent. The Fraunhofer Institute for Silicate Research ISC teamed up with the Fraunhofer Institute for Molecular Biology and Applied Ecology IME and the Institute of Tropical Medicine at the University of Tübingen for a new test method to detect malaria parasites in blood. The idea of the research project “NanoFRET” is to develop a highly sensitive and reliable rapid diagnostic test so that patient treatment can begin as early as possible.

Malaria is caused by parasites transmitted by mosquito bite. The most dangerous form of malaria is malaria tropica. Left untreated, it is fatal in most cases....

Im Focus: A “cosmic snake” reveals the structure of remote galaxies

The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.

Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...

Im Focus: Visual intelligence is not the same as IQ

Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.

That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...

Im Focus: Novel Nano-CT device creates high-resolution 3D-X-rays of tiny velvet worm legs

Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.

During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....

Im Focus: Researchers Develop Data Bus for Quantum Computer

The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.

Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...
