2 NASA satellites catch Tropical Storm Nate's quick formation

09.09.2011
NASA's Aqua and TRMM satellites were on guard when Tropical Storm Nate developed late in the day yesterday, Sept. 7 in the Bay of Campeche near the east coast of Mexico. The satellites measured cloud height, temperature and rainfall rates and found the heaviest rainfall on the southern side of the tropical storm.

The Atmospheric Infrared Sounder (AIRS) instrument on NASA's Aqua satellite took an infrared image of Tropical Storm Nate on Sept. 7 at 3:59 p.m. EDT, one hour before Nate was named a tropical storm. The infrared data showed the coldest cloud top temperatures (-63 Fahrenheit/-52 Celsius) and strongest thunderstorms with the heaviest rainfall were still off-shore from eastern Mexico and over the Bay of Campeche. On the morning of Sept. 8, the strongest convection (rapidly rising air that forms the thunderstorms that power a tropical cyclone) were mostly in the southwest quadrant of the storm.


NASA's TRMM satellite flew over Nate on Sept. 7 at 1812 UTC (2:12 p.m. EDT), a couple of hours before being designated a tropical storm. Cloud tops were up to 14km (~8.7 miles) high south of Nate's center. The yellow and green areas indicate moderate rainfall between .78 to 1.57 inches per hour. Red areas are considered heavy rainfall at almost 2 inches (50 mm) per hour. Credit: Credit: SSAI/NASA, Hal Pierce

Today, Nate is still meandering around in the Bay of Campeche with nothing to guide him, but that will change over the weekend as a ridge (elongated area) of high pressure is expected to develop over Mexico and bring Nate westward.

A tropical storm warning is in effect in Mexico from Chilitepec to Celestun, where 2 to 4 inches of rainfall is expected with isolated amounts as high as 8 inches in the Mexican states of Campeche, Tabasco and southern Veracruz. Tropical storm-force winds are expected today in the warning area. Nate is expected to create a storm surge of 1 to 3 feet above normal tidal levels in the warning area along the immediate coast.

At 8 a.m. EDT on Sept. 8, Nate's maximum sustained winds were near 45 mph, and are expected to strengthen in the warm waters of the Bay. Nate was located about 125 miles (200 km) west of Campeche Mexico near 20.2 North and 92.4 West. Nate is creeping to the southeast near 1 mph (2 kmh) and has a minimum central pressure of 1003 millibars.

The TRMM satellite, which is managed by both NASA and the Japanese Space Agency, got a good look at the rainfall rates occurring in Nate yesterday. The Tropical Rainfall Measuring Mission (TRMM) satellite flew over Nate on Sept. 7 at 1812 UTC (2:12 p.m. EDT), a couple of hours before being designated a tropical storm. Data from TRMM's Precipitation Radar (PR) showed that the forming tropical cyclone had areas of heavy convection with cloud tops reaching to heights of about 14km (~8.7 miles) south of Nate's center of circulation. That coincides with the infrared data from NASA's Aqua satellite, which showed the coldest, highest cloud tops in that same area. The strongest rainfall was on the south-southwestern quadrant where rainfall rates were as high as 2 inches (50 mm) per hour.

The forecast from the National Hurricane Center calls for Nate to become a hurricane over the weekend and make landfall in eastern Mexico early next week.

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,...
