2014-03-10 13:24:01

NASA/Goddard Space Flight Center Tropical Cyclone Lusi has spawned warnings and watches in the Solomon Islands, Vanuatu, and New Zealand as it moves through the South Pacific Ocean. NASA's Terra and Aqua satellites provided visible and infrared views of the storm that revealed it has become better organized. NASA's Terra satellite captured a visible image of Tropical Cyclone Lusi over Vanuatu on March 9 at 23:30 UTC. The image showed towering thunderstorms surrounded the center and...

Double Tropical Trouble For Queensland, Australia Seen By NASA
2014-03-07 15:08:46

Rob Gutro, NASA There are two developing areas of tropical low pressure that lie east and west of Queensland, Australia. System 96P and System 98P, respectively. The MODIS instrument that flies aboard both NASA's Aqua and Terra satellites captured images of both tropical trouble-makers as each satellite passed overhead on March 7. In the Coral Sea, part of the Southwestern Pacific Ocean, System 96P was just 125 nautical miles/143.8 miles/231.5 km north-northeast of Willis Island,...

A team of researchers exploring the aerodynamics of flying snakes finds that whirls of wind, the little vortices surrounding it, give them an extra lift. WASHINGTON, March 4, 2014 /PRNewswire-USNewswire/ -- Animal flight behavior is an exciting frontier for engineers to both apply knowledge of aerodynamics and to learn from nature's solutions to operating in the air. Flying snakes are particularly intriguing to researchers because they lack wings or any other features that remotely...

Hurricanes Could Be Tamed By Offshore Wind Farms
2014-02-26 11:45:18

Brett Smith for redOrbit.com - Your Universe Online In addition to providing a renewable source of energy and reducing society’s carbon footprint, wind turbines may provide the added benefit of taming the power of a hurricane. According to a new study in the journal Nature Climate Change, thousands of offshore wind turbines could diminish hurricanes' wind speeds, wave heights and storm surge. "We found that when wind turbines are present, they slow down the outer rotation winds of...

New Hurricane Model Can More Accurately Predict Storm Path, Intensity
2014-02-26 07:15:48

Brett Smith for redOrbit.com - Your Universe Online When Hurricane Sandy slammed into southern New Jersey in October 2012, it had essentially confounded both the NOAA's Global Forecast System (GFS) and the European Centre for Medium-Range Weather Forecasts (ECMWF). Now, a new real-time hurricane analysis system being developed at Penn State University has been shown to accurately predict the track and intensity of the deadly storm. "For this particular study aircraft-based Doppler...

A barometer is an instrument that measures atmospheric pressure. The barometer measures pressure exerted by the atmosphere using water, air, or mercury. Through measuring the pressure one can forecast short term weather changes. Evangelista Torricelli is credited with the invention of the barometer in 1643. However, Gasparo Berti unintentionally built a water barometer around the same time. Rene Descartes was also noted as describing an experiment to determine air pressure but there is no...

A Vortex (plural: vortices) is a spinning, often turbulent, mass of flowing fluid. Any spiral movement with a closed streamline is considered vortex flow. The speed and rate of rotation of a vortex is always greatest at the center, with progressively decreasing speed away from the center. The fluid pressure is lowest in the center of the vortex, and rises further from the center (Bernoulli's Principle). The core of a vortex is sometimes visible due to a plume of water vapor caused by...

Turbulence (or turbulent flow) is characterized by chaotic, random property changes. Turbulence occurs with low momentum diffusion (spreading of atmospheric properties), high momentum convection (vertical transference of atmospheric properties), and rapid variation of pressure and velocity in both space and time. A flow that is not turbulent is known as laminar flow. A vortex moving at low speeds will most likely cause laminar flow, and as speeds increase a transition is made to turbulent...

Comet -- A comet is a small body from the outer reaches of the solar system similar to an asteroid but composed of ice. Often described as "dirty snowballs," they are composed largely of carbon dioxide ice, methane ice, and water ice with a mixture of dust and small stony aggregates mixed in. Comets are thought to be small pieces of debris left over from the formation of the solar system, representing a sample of the original composition of the nebula that condensed to form the Sun and all...
