NASA satellites see Nicole become a remnant, another low soaking US East Coast

01.10.2010
Tropical Storm Nicole was a tropical storm for around 6 hours before it weakened into a remnant low pressure area and is now off the Florida coast. NASA Satellite imagery captured different views of Nicole's clouds as the system weakened back into a low pressure area.
While Nicole weakened, a huge trough of low pressure over the U.S. eastern seaboard from Florida to Maine has become the key weathermaker there. The trough, an elongated area of low pressure, is streaming tropical moisture from Nicole's remnants and the Gulf of Mexico, bringing high rainfall totals and severe weather up and down the coast.

At 2 a.m. EDT on Sept. 30, Nicole's remnant low was still 35 miles east of Fort Lauderdale, Fla. and about 65 miles west-southwest of Freeport, the Bahamas. Nicole's remnants are forecast to merge with the giant trough (an elongated area of low pressure) later today or early Friday. Nicole's remnants, barely discernable on satellite imagery now because of the huge trough to its west, will still be bringing locally heavy rainfall over the Bahamas. There's just a 10 percent chance it will regenerate as a subtropical cyclone in the next 24 hours.

NASA\'s CloudSat satellite passed through the western section of Tropical Storm Nicole on Sept. 29, 2010, at 0727 UTC (3:27 a.m. EDT). The CloudSat image captured areas of light cumulus precipitation mixed with a stream of mid- level cloudiness, most likely altocumulus and altostratus. Deep mid-level flow from the south-southwest was evident in the image, occurring from the inclination of the clouds towards the north-northeast. Credit: NASA/JPL/Colorado State Univ./NRL

The GOES-13 satellite captured a visible image of the extensive cloud cover of the trough (elongated area of low pressure) all along the U.S. East coast on Sept. 30 at 1345 UTC (9:45 a.m. EDT) that is feeding off tropical moisture from the Gulf of Mexico, and Nicole's remnants. GOES satellites are operated by NOAA and the NASA GOES Project at NASA's Goddard Space Flight Center, Greenbelt, Md. uses the satellite data to create images and animations.

NASA's CloudSat satellite passed through the western section of Tropical Storm Nicole on September 29, 2010 at 0727 UTC (3:27 a.m. EDT). CloudSat captured an image of the elongated storm system when it was located between Cuba and Florida was in the beginning stages of tropical cyclone formation. CloudSat imagery noticed that low level cyclonic circulation was developing around the low pressure area, as it was being fueled by warm sea surface temperatures.

The CloudSat image captured areas of light cumulus precipitation mixed with a stream of mid- level cloudiness, most likely altocumulus and altostratus. Deep mid-level flow from the south-southwest was evident in the image, occurring from the inclination of the clouds towards the north-northeast.

On Sept. 28 at 18:20 UTC 2:20 p.m. EDT the Moderate Resolution Imaging Spectroradiometer (MODIS) instrument on NASA's Aqua satellite captured a visible image of Tropical Storm Nicole over Cuba before it weakened back into a tropical depression. Nicole was already losing her cyclonic shape at that time.

The National Hurricane Center issued its final official forecast for Nicole on Sept. 29 at 5 p.m. EDT. At that time, Nicole had maximum sustained winds near 40 mph. It was about 175 miles east-northeast of Havana, Cuba and 165 miles west of Nassau near 24.5 North and 80.0 West. It was moving north-northeast near 12 mph and had a minimum central pressure of 996 millibars. At that time, it had degenerated into an elongated area of low pressure and the National Hurricane Center noted that the ill-defined low had become untrackable.

Forecasters are also watching a low pressure area in the eastern Caribbean. A large area of disturbed weather associated with two tropical waves is about 800 miles east of the Windward Islands. The showers and thunderstorms in it are currently disorganized but it is expected to move into more favorable conditions. It currently has a 30 percent chance of becoming a tropical depression in the next 48 hours, so Cuba is watching it closely after being soaked by Nicole.

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...
