Two NASA satellites captured the height and temperatures of Felicia's clouds to assist meteorologists in their forecasts as she approaches Hawaii. She's already stirring up the surf.
A Tropical Storm Watch Remains in effect for Oahu, the Big Island of Hawaii and for all of Maui County, which includes the islands of Maui, Kahoolawe, Lana, and Molokai. A tropical storm watch means that tropical storm conditions are possible within the watch area. If Felicia does not weaken to a tropical depression later today...a tropical storm warning may be required for portions of the watch area.The Central Pacific Hurricane Center in Honolulu, Hawaii noted in their discussion "a large swell generated by Felicia is already affecting the main Hawaiian islands. This swell will continue to build across the state today and tonight. Also...regardless of the intensity of Felicia when it reaches the Hawaiian Islands...locally heavy rainfall is still expected to occur and flash flooding remains a possibility."
NASA's CloudSat satellite's Cloud Profiling Radar captured a side view of Felicia on August 9 at 7 p.m. EDT (23:00 UTC). The image indicated Felicia's cloudtops are almost 13 kilometers (8 miles) high, down about 2 kilometers over the last several days, which indicates a weakening storm. Higher clouds indicate stronger uplift in a storm, and a more powerful hurricane.
Meanwhile, another satellite and instrument are taking Felicia's cloud temperatures from space. The Atmospheric Infrared Sounder (AIRS) is an instrument that flies aboard NASA's Aqua satellite and takes infrared images that reveal temperatures of clouds. NASA false-colors the images to show temperature differences, and the lowest temperatures (in purple) are associated with high, cold cloud tops that make up the top of the area of low pressure. Those temperatures are as cold as or colder than 220 degrees Kelvin or minus 63 degrees Fahrenheit (F). The blue areas are around 240 degrees Kelvin, or minus 27F. Felicia's cloud top temperatures are mostly blue, indicating lower clouds.
On August 10, at 11 a.m. EDT (5 a.m. Hawaii Time) Felicia had maximum sustained winds near 45 mph, and is expected to continue weakening as it affects Hawaii. It was moving west near 12 mph, and had a minimum central pressure near 1005 millibars. It was located about 3225 miles east of Hilo, Hawaii near 20.5 north and 150.2 west.
Increasing upper level winds continue to batter at Felicia, further weakening the tropical storm. Those winds will continue and Felicia is expected to drop to a tropical depression by late tonight, Aug. 10 or early on Aug. 11 despite traveling through warm ocean waters.
Residents can expect large ocean swells, gusty winds and heavy downpours over the next couple of days.

Climate change: In their old age, trees still accumulate large quantities of carbon

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,...
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...
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...
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...
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...
