NASA sees bitter cold cloud tops in newborn Tropical Storm Carlotta

15.06.2012
Bitter cold cloud tops tell forecasters that a storm has a lot of uplift, and the colder the cloud tops, the higher they are in the atmosphere, and the stronger the thunderstorms.

NASA's Aqua satellite data showed that the cloud top temperatures in newborn Tropical Storm Carlotta became colder overnight and continue to grow colder as the low pressure area formely known as System 94E strengthened into a tropical storm. Carlotta is even expected to strengthen further and become a hurricane.


NASA's AIRS instrument data showed on June 14, at 0723 UTC (3:23 a.m. EDT/12:23 a.m. PDT) that Tropical Storm Carlotta's low-level circulation center had consolidated and shows improved convective banding (of thunderstorms). Credit: Credit: NASA/JPL, Ed Olsen

Because Carlotta is expected to continue strengthening, the government of Mexico has issued a hurricane warning for the Pacific coast of Mexico From Salina Cruz to Punta Maldonado. A hurricane watch is also in effect for the Pacific coast of Mexico west of Punta Maldonado to Acapulco and east of Salina Cruz to Barra De Tonala.

Forecasters look at data from the Atmospheric Infrared Sounder (AIRS) instrument that flies on NASA's Aqua satellite. When cloud temperatures get colder, it means that clouds are getting higher. The lowest temperatures in Carlotta were as cold as or colder than 220 degrees Kelvin or minus 63 degrees Fahrenheit (-52 Celsius). The data from AIRS is also used to create an accurate 3-D map of atmospheric temperature, water vapor and clouds, all of which are helpful to forecasters.

At 11 a.m. EDT (8 a.m. PDT) Tropical Storm Carlotta's maximum sustained winds were near 45 mph (75 kph), and further strengthening is expected in the warm waters along the western coast of Mexico. Carlotta is expected to become a hurricane on June 15, according to the National Hurricane Center. Currently, Carlotta is located about 385 miles (620 km) south-southeast of Puerto Angel and 590 miles (950 km) southeast of Acapulco, Mexico. Carlotta is moving northwest near 9 mph (15 kph) and is expected to continue for the next couple of days. The storm should be near the Pacific coast of Mexico on Friday and move near the coast Friday night and Saturday, according to the National Hurricane Center.

That means that hurricane conditions are expected in the warning area by Friday night, June 15 and those conditions will continue on June 16, Saturday. Storm surge, heavy rainfall, flooding and mudslides are also possible. Isolated rainfall totals can reach 10-12 inches (250-300 mm) over the Mexican states of Guerrero, Oaxaca, Chiapas and southern Guatemala.

Im Focus: Manipulating Electron Spins Without Loss of Information

Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.

For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...

Im Focus: The proton precisely weighted

What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.

To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
