NASA satellites confirm Tropical Storm Bret's heaviest rains on the eastern side

21.07.2011
Two NASA Satellites confirmed that the heaviest rainfall in Tropical Storm Bret is occurring in the eastern side of the storm. One satellite using precipitation radar measured rainfall, and another satellite using infrared light measured cloud-top temperatures which indicate strength of thunderstorms.

The Tropical Rainfall Measuring Mission (TRMM) satellite flew over tropical storm Bret in the Atlantic Ocean north of the Bahamas on July 19, 2011 at 1118 UTC ( 7:18 a.m. EDT). The early morning pass showed that Bret was very small but TRMM's Precipitation Radar showed that the storm had some powerful thunderstorms reaching to heights of 15km (9.3 miles) in the eastern quadrant of the storm.


NASA's TRMM satellite captured this image of rainfall happening within Tropical Stort on July 19. The strongest thunderstorms were as high as 9.3 miles (15 km) and had the heaviest rainfall (red) on the east side of the storm, falling at 2 inches (50 mm) per hour. The yellow and green areas indicate moderate rainfall between .78 to 1.57 inches (20 to 40 mm) per hour. Credit: NASA/SSAI, Hal Pierce

NASA's Aqua satellite passed over Tropical Storm Bret seven hours later than TRMM did on July 19 at 18:35 UTC (2:35 p.m. EDT). NASA's Atmospheric Infrared Sounder (AIRS) imagery confirmed what TRMM showed by measuring very cold (-63F/-52C) cloud top temperatures. Bret still had strong thunderstorms east of the center of circulation.

At 5 a.m. EDT Tropical Storm Bret's maximum sustained winds were near 50 mph (85 kmh) although gradual weakening is forecast to occur over the next two days. Bret's center is near latitude 31.1 North and longitude 74.4 West. Bret is moving toward the northeast near 7 mph (11 kmh) and is expected to continue in that direction while speeding up. Bret's minimum central pressure is 1001 millibars.

Bret is forecast to run into strong wind shear and dry air, two factors that will take the wind out of his sails in the next couple of days.

Im Focus: Scientists channel graphene to understand filtration and ion transport into cells

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.

To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...

Im Focus: Towards data storage at the single molecule level

The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.

Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
