NASA Sees Eastern Pacific Get First Tropical Storm: Alvin

NASA’s Aqua satellite and NOAA’s GOES-15 satellite captured imagery of the Eastern Pacific Ocean’s first named tropical storm, Alvin. Aqua and GOES-15 provided imagery of Alvin that provided a look at the overall storm and the temperatures of its cloud tops.

NASA’s Aqua satellite flew over Tropical Storm Alvin just as it reached tropical storm status on May 15 at 2047 UTC (4:47 p.m. EDT). The Atmospheric Infrared Sounder (AIRS) instrument that flies aboard Aqua captured an infrared image of the storm that showed bands of thunderstorms on the tropical storm’s western side were wrapping into the low-level center. Those bands of thunderstorms became more organized and more tightly wrapped by May 16 as the storm strengthened further.

AIRS data is infrared and gives an indication of temperature. With respect to tropical cyclones, AIRS provides temperatures of cloud tops and surrounding ocean surface temperatures, two factors important in determining the strength of a storm and what may happen with it. Cold cloud top temperatures, such as those seen in some of the bands around Alvin were near -62 Fahrenheit (-52 Celsius) and are indicative of strong uplift that can create strong, high thunderstorms with heavy rain potential.

NOAA’s GOES-15 satellite captured a near-infrared view of Tropical Storm Alvin on May 16 at 1200 UTC (8 a.m. EDT) as it continued moving west and away from Mexico. This near-infrared view showed that Alvin had become more tightly wrapped and more organized. According to the National Hurricane Center, satellite imagery of Alvin shows very deep convection resembling a central dense overcast, but noted that the low-level center is displaced a fair distance west of the strongest convection (rising air that creates thunderstorms that make up the tropical cyclone).

AIRS imagery is produced at NASA’s Jet Propulsion Laboratory in Pasadena, Calif. and GOES imagery is created at NASA’s GOES Project, located at NASA’s Goddard Space Flight Center in Greenbelt, Md.

At 5 a.m. EDT on May 15, Alvin had maximum sustained winds near 50 mph (85 kph). It was located far from land, about 705 miles (1,135 km) south-southwest of Manzanillo, Mexico, near 9.1 north latitude and 106.9 west longitude. Alvin was moving to the west-northwest at 10 mph (17 kph) and had a minimum central pressure near 1003 millibars. Twenty four hours before, Alvin’s central pressure was near 1006 millibars. A drop in pressure indicates a strengthening low pressure area.

The National Hurricane Center noted that Alvin will be moving through warm waters over the next couple of days in the Eastern Pacific Ocean and is expected to reach hurricane strength by early on May 18 before weakening over the weekend of May 18 and 19.

Im Focus: Space observation with radar to secure Germany's space infrastructure

Satellites in near-Earth orbit are at risk due to the steady increase in space debris. But their mission in the areas of telecommunications, navigation or weather forecasts is essential for society. Fraunhofer FHR therefore develops radar-based systems which allow the detection, tracking and cataloging of even the smallest particles of debris. Satellite operators who have access to our data are in a better position to plan evasive maneuvers and prevent destructive collisions. From April, 25-29 2018, Fraunhofer FHR and its partners will exhibit the complementary radar systems TIRA and GESTRA as well as the latest radar techniques for space observation across three stands at the ILA Berlin.

The "traffic situation" in space is very tense: the Earth is currently being orbited not only by countless satellites but also by a large volume of space...

Im Focus: Researchers Discover New Anti-Cancer Protein

An international team of researchers has discovered a new anti-cancer protein. The protein, called LHPP, prevents the uncontrolled proliferation of cancer cells in the liver. The researchers led by Prof. Michael N. Hall from the Biozentrum, University of Basel, report in “Nature” that LHPP can also serve as a biomarker for the diagnosis and prognosis of liver cancer.

The incidence of liver cancer, also known as hepatocellular carcinoma, is steadily increasing. In the last twenty years, the number of cases has almost doubled...

Im Focus: Researchers at Fraunhofer monitor re-entry of Chinese space station Tiangong-1

In just a few weeks from now, the Chinese space station Tiangong-1 will re-enter the Earth's atmosphere where it will to a large extent burn up. It is possible that some debris will reach the Earth's surface. Tiangong-1 is orbiting the Earth uncontrolled at a speed of approx. 29,000 km/h.Currently the prognosis relating to the time of impact currently lies within a window of several days. The scientists at Fraunhofer FHR have already been monitoring Tiangong-1 for a number of weeks with their TIRA system, one of the most powerful space observation radars in the world, with a view to supporting the German Space Situational Awareness Center and the ESA with their re-entry forecasts.

Following the loss of radio contact with Tiangong-1 in 2016 and due to the low orbital height, it is now inevitable that the Chinese space station will...

Im Focus: Alliance „OLED Licht Forum“ – Key partner for OLED lighting solutions

Fraunhofer Institute for Organic Electronics, Electron Beam and Plasma Technology FEP, provider of research and development services for OLED lighting solutions, announces the founding of the “OLED Licht Forum” and presents latest OLED design and lighting solutions during light+building, from March 18th – 23rd, 2018 in Frankfurt a.M./Germany, at booth no. F91 in Hall 4.0.

They are united in their passion for OLED (organic light emitting diodes) lighting with all of its unique facets and application possibilities. Thus experts in...
