2 satellites see Tropical Storm Ophelia born in the Atlantic

22.09.2011
Tropical Storm Ophelia was born today in the Atlantic Ocean and captured in an infrared image from NOAA's GOES-13 satellite and NASA's Aqua satellite.

NASA and NOAA satellites were watching the low pressure System 98L in the central Atlantic yesterday when it was 1450 miles east of the Leeward Islands.

Yesterday, Sept. 20, 2011 at 4:11 p.m. NASA's Aqua satellite flew over System 98L before it became a tropical storm. An infrared image from the Atmospheric Infrared Sounder instrument onboard showed System 98L's strongest thunderstorms and coldest cloud tops (colder than -63F/-52C) were banded north and south of the center of circulation. Those bands of thunderstorms were a sign that the low pressure area was organizing and strengthening.

While the U.S. was asleep, System 98L organized and strengthened further into Tropical Storm Ophelia. By the early morning of Sept. 21, her center was near 12.7 North latitude and 41.8 West longitude, about 1370 miles east of the Leeward Islands. Her minimum central pressure is 1005 millibars. Ophelia has maximum sustained winds near 45mph. Those tropical storm-force winds extend out to 175 miles making Ophelia a good-sized tropical storm, about 350 miles in diameter.

An image from NOAA's GOES-13 satellite was captured at 4:45 a.m. that shows Ophelia as a large and still disorganized area of clouds. The image was created by the NASA GOES Project at NASA's Goddard Space Flight Center in Greenbelt, Md. The image shows curved bands of thunderstorms mostly over the northern and southern quadrants of the storm. Infrared satellite data shows that there's not much convection (rapidly rising air that forms the thunderstorms that power a tropical cyclone) near the storm's center.

Ophelia is still too far away from land for watches or warnings. She's moving west at 14 mph (20 kmh) and the National Hurricane Center expects to Ophelia to continue in that direction while strengthening over the next day in the warm waters of the central tropical Atlantic.

Thereafter, however, the southwesterly wind shear is expected to shift more westerly and increase because of an upper-level low pressure area forming north of Puerto Rico. Increasing wind shear will likely prevent further intensification, but satellites are keeping an eye on what's happening under the hood of Ophelia's clouds.

According to the National Hurricane Center forecast track, interests in the Northern Leeward Islands and Puerto Rico will feel the effects of Ophelia late in the weekend.

Im Focus: Can we see monkeys from space? Emerging technologies to map biodiversity

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.

Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...

Im Focus: Climate satellite: Tracking methane with robust laser technology

Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.

Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...

Im Focus: How protons move through a fuel cell

Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.

As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...

Im Focus: A unique data centre for cosmological simulations

Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.

With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
