NASA caught Tropical Storm Rina forming, strengthening

25.10.2011
NASA's Tropical Rainfall Measuring Mission satellite called "TRMM" and NASA's Aqua satellite captured radar and temperature data that showed Tropical Storm Rina forming in the western Caribbean Sea yesterday. Today, Rina continues strengthening.

The National Hurricane Center (NHC) upgraded an area of disturbed weather in the Caribbean to tropical depression eighteen and then to tropical storm Rina on October 23, 2011. The TRMM satellite flew over the forming tropical cyclone on October 23, 2011 at 1728 UTC (1:28 p.m. EDT).


This infrared image of the eastern half of Tropical Storm Rina was taken on Oct. 24 at 2:47 a.m. EDT from the AIRS instrument on NASA's Aqua satellite. It shows a very large area of strong convection and thunderstorms around the center (purple) of circulation. Cloud top temperatures were colder than -63F (-52C) in that area, indicating strong thunderstorms and heavy rainfall. Credit: NASA/JPL, Ed Olsen

Data from TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) was used to create a rainfall image from the TRMM team at NASA's Goddard Space Flight Center in Greenbelt, Md. The rainfall image showed that the future storm already was well organized and had a large area of heavy rainfall extending toward the northeast from eastern Honduras. Up until the morning hours (local time) on Monday, October 24, Honduras had a tropical storm watch in effect for its northeastern coast. That watch was dropped by 10 a.m. EDT as Rina moved away.

Today, Oct. 24, that rainfall is affecting the northeastern coast of Honduras and Cayman Islands. The NHC said "Rina is expected to produce total rain accumulations of 1 to 3 inches along the northeast coast of Honduras. Rainfall amounts of 2 to 4 inches are possible over the Cayman Islands."

At 11 a.m. EDT on Oct. 24, Rina's maximum sustained winds were near 45 mph (75 kmh). Those tropical storm-force winds extend out 85 miles (140 km) from the center, making Rina a small tropical storm over 170 miles in diameter.

Rina is in an environment with warm water (over the 80F/26.6C threshold needed to maintain a tropical cyclone) and low wind shear. It is centered near 17.1 North latitude and 82.9 West longitude, which is about 190 miles (305 km) southwest of Grand Cayman and 370 miles (595 km) east-southeast of Chetumal, Mexico. Rina was moving to the northwest at 6 mph (9 kmh). Minimum central pressure is 1001 millibars.

When NASA's Aqua satellite passed over Rina earlier today at 2:47 a.m. EDT the Atmospheric Infrared Sounder (AIRS) instrument took an infrared reading of Rina's cloud top temperatures. The colder the cloud top temperatures, the higher and stronger they are. AIRS temperature data showed a very large area of strong convection and thunderstorms around the center of circulation where cloud top temperatures were colder than -63F (-52C). Those temperatures indicate strong thunderstorms and heavy rainfall. AIRS infrared data showed that Rina continues to become better organized. The AIRS data was created into a color-coded image at NASA's Jet Propulsion Laboratory in Pasadena, Calif.

There are a couple of factors steering Rina through the Caribbean Sea. In the mid-level of the atmosphere there's a ridge (elongated area) of high pressure building over the northern Gulf of Mexico, which is expected to turn Rina to the west-northwest. The NHC noted that as the ridge moves eastward in a couple of days, it will take Rina northwest, then northward. The NHC expects Rina to become a hurricane tomorrow.

Im Focus: Attoseconds break into atomic interior

A newly developed laser technology has enabled physicists in the Laboratory for Attosecond Physics (jointly run by LMU Munich and the Max Planck Institute of Quantum Optics) to generate attosecond bursts of high-energy photons of unprecedented intensity. This has made it possible to observe the interaction of multiple photons in a single such pulse with electrons in the inner orbital shell of an atom.

In order to observe the ultrafast electron motion in the inner shells of atoms with short light pulses, the pulses must not only be ultrashort, but very...

Im Focus: Good vibrations feel the force

A group of researchers led by Andrea Cavalleri at the Max Planck Institute for Structure and Dynamics of Matter (MPSD) in Hamburg has demonstrated a new method enabling precise measurements of the interatomic forces that hold crystalline solids together. The paper Probing the Interatomic Potential of Solids by Strong-Field Nonlinear Phononics, published online in Nature, explains how a terahertz-frequency laser pulse can drive very large deformations of the crystal.

By measuring the highly unusual atomic trajectories under extreme electromagnetic transients, the MPSD group could reconstruct how rigid the atomic bonds are...

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.

In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...
