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.

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their work in the journal Science.
Topological insulators are currently the hot topic in physics according to the newspaper Neue Zürcher Zeitung. Only a few weeks ago, their importance was...
In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
