NASA's TRMM Satellite Sees Hot Towers in Cyclone Koji

12.03.2012
Hot towers, or towering thunderclouds that give off an excessive amount of latent heat, usually indicate a tropical cyclone will strengthen in six hours, and NASA's TRMM satellite saw some of them as it passed by Tropical Storm Koji.

The Tropical Rainfall Measuring Mission (TRMM) satellite passed directly above an intensifying tropical storm in the South Indian Ocean called Koji on March 8, 2012 at 2053 UTC (3:53 p.m. EST). A rainfall analysis was made from TRMM Microwave Imager (TMI) and Precipitation Radar (PR) data. Those TRMM data reveal that Koji was getting organized with bands of heavy rainfall spiraling into the storm's center.

One of its most important features of TRMM's Precipitation Radar (PR) instrument is its ability to provide three dimensional profiles of precipitation from the surface up to a height of about 20km (12 mile). PR data from the flight over tropical storm Koji are shown in the 3-D image above. Those data reveal that an eye hadn't formed but powerful storm towers around KOJI's center were reaching heights of almost 15 km (~9.3 miles).

On March 8, 2012 at 0900 UTC (4 a.m. EST), Tropical Storm Koji had maximum sustained winds near 55 knots (63.2 mph/102 kph). It was located near 17.1 South and 86.1 East, about 1000 miles southeast of Diego Garcia and moving to the west at 12 knots (13.8 mph/22.2 kph).

Koji has been predicted to increase in intensity and reach hurricane force with peak winds of 70kts (~80 mph) on March 8, 2012. Koji is predicted to remain at hurricane force for only one day and then weaken while traveling southwestward of the open waters of the South Indian Ocean.

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...

Im Focus: In best circles: First integrated circuit from self-assembled polymer

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...
