NASA satellites see high, cold thunderstorm cloud tops in Tropical Depression 2

12.07.2010
NASA's Aqua and TRMM satellites confirmed that Tropical Depression Two (TD2) had some strong, high thunderstorms a day after its center made landfall. TD2 appears elongated on satellite imagery, and its rains stretch from southeastern Texas to northeastern Mexico. Those rains are still prompting flash flood watches and warnings.

NASA's Atmospheric Infrared Sounder (AIRS) instrument that flies aboard NASA's Aqua satellite captured an infrared look at TD2's high thunderstorm cloud tops on July 8 at 19:29 UTC (3:29 p.m. EDT) as its rains stretched from southeastern Texas to northeastern Mexico. The coldest cloud tops were as cold as -63F, and indicate areas of heavy rainfall.

Earlier in the day at 1020 UTC (6:20 a.m. EDT), the Tropical Rainfall Measuring Mission (TRMM) satellite flew over TD2 creating data used in a rainfall analysis. At that time, a small area of very heavy thunderstorms was located over the Gulf of Mexico east of the Texas-Mexico coast. TRMM's precipitation radar showed that some of the thunderstorms had tops extending upward to almost 15km (~9.3 miles), which indicate very strong storms, likely with heavy rainfall.

On Friday, July 9, at 5 a.m. EDT, the National Weather Service's Hydrometeorological Prediction Center (HPC) in Camp Springs, Md. noted that "Locally heavy rains continue to spread across the Rio Grande Valley."

As TD2's rainfall continues to sweep warm, moisture in from the Gulf of Mexico, flood and flash flood watches remain in effect across much of Texas. Coastal flood warnings remain in effect along portions of the western Gulf coast.

Some rain totals from the National Weather Service range from 2 inches to 5 inches in various locations. The largest rainfall total recorded was 5.16 inches at the Hads Guadalupe River in Victoria, Texas. Bloomington received 3.6 inches, Victoria Regional Airport received 2.86 inches, and Fort Hood received 2.47 inches.

The flood warning continues for the Guadalupe River near Bloomington affecting Calhoun and Victoria Counties in Texas, as recent heavy rainfall over the area will result in river rises above flood stage during the next few days.

At 5 a.m. EDT, TD2's center was about 115 miles southwest of Laredo, Texas near 26.5 North and 100.9 West. Maximum sustained winds were near 20 mph with higher gusts, and TD2 is expected to move farther inland into the higher terrain of northern Mexico later today or tonight, and dissipate over the weekend.

The HPC said that "Locally heavy showers will continue across Texas for the next couple of days. Additional rainfall amounts of 1 to 3 inches are possible...with isolated maximum totals of up to 8 inches for localized areas along the Texas/Mexico border."

Im Focus: Fizzy soda water could be key to clean manufacture of flat wonder material: Graphene

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.

As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...

Im Focus: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...

Im Focus: Circular RNA linked to brain function

For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.

While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

Im Focus: RAVAN CubeSat measures Earth's outgoing energy

An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.

The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...

Im Focus: Scientists shine new light on the “other high temperature superconductor”

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.

Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
