Category 4 Cyclone Giri hits Burma, NASA satellite sees heavy rainfall

25.10.2010
Tropical Storm 04B grew quickly into powerful Cyclone Giri and was making landfall in Burma today as a powerful Category Four Cyclone on the Saffir-Simpson scale. NASA's TRMM satellite noticed that the storm contained some heavy rainfall in addition to the powerful winds.

Giri is the second tropical cyclone of 2010 to form in the Bay of Bengal and was seen by the Tropical Rainfall Measuring Mission (TRMM) satellite. Cyclone Giri was seen clearly by the TRMM satellite twice on Oct. 21.


This TRMM rainfall rate image captured on Oct. 21 at 1534 UTC (11:34 a.m. EDT) shows moderate to heavy rain showers were surrounding Cyclone Giri\'s partially-formed eye. Red indicates heavy rainfall at more than 2 inches per hour. The yellow and green areas indicate moderate rainfall between .78 to 1.57 inches per hour.

The first good view was at 1534 UTC (11:34 a.m. EDT) when TRMM data showed a very well organized storm with heavy rainfall south of Giri's partially formed eye. The heaviest rainfall was falling at about 2 inches per hour, south of Giri's eye. The rainfall analysis was done at NASA's Goddard Space Flight Center, Greenbelt, Md.

The second TRMM orbit at 2347 UTC (7:47 p.m. EDT) captured Giri's rainfall when the wind speeds had increased to 85 knots (98 mph) making it a category two tropical cyclone on the Saffir-Simpson scale. The second TRMM image showed that Giri had developed a closed eye surrounded by powerful thunderstorms dropping heavy rainfall. Cyclone Giri then intensified to a category four tropical cyclone with wind speeds estimated at 125 knots (~144mph) before striking Burma's west coast in the middle of the morning.

On Oct. 22 at 1500 UTC (11 a.m. EDT) Cyclone Giri had maximum sustained winds near 135 knots (155 mph) and was weakening as it continued to move inland. Giri's center was about 180 nautical miles south-southeast of Chittagong, Bangladesh near 20.1 North and 93.7 East. It was moving north-northeast at 10 mph.

Satellite data also indicated that as Giri was making landfall, that it had a well-defined eye about 20 nautical miles wide. High waves, coastal erosion, severe winds of Category four hurricane force and very heavy rainfall are all being experienced along coastal areas of Hunters Bay and Combermere Bay. As Giri moves inland over the rugged terrain of Myanmar it will rapidly weaken and drop large amounts of rain.

Im Focus: Future electronic components to be printed like newspapers

A new manufacturing technique uses a process similar to newspaper printing to form smoother and more flexible metals for making ultrafast electronic devices.

The low-cost process, developed by Purdue University researchers, combines tools already used in industry for manufacturing metals on a large scale, but uses...

Im Focus: First evidence on the source of extragalactic particles

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.

To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...

Im Focus: Magnetic vortices: Two independent magnetic skyrmion phases discovered in a single material

For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.

Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...

Im Focus: Breaking the bond: To take part or not?

Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.

A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...

Im Focus: New 2D Spectroscopy Methods

Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.

"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....
