NASA/Goddard Space Flight Center Tropical Storm 02B was renamed Tropical Cyclone Nilam when NASA's Aqua satellite captured an infrared image of the storm soaking Sri Lanka on its crawl to a landfall in southern India. The Atmospheric Infrared Sounder (AIRS) instrument aboard NASA's Aqua satellite captured an infrared image of Tropical Cyclone Nilam on Oct. 29 at 2029 4:29 p.m. EDT. At the time of the AIRS image, the strongest storms with coldest cloud top temperatures were covering Sri...
redOrbit Meteorologist Joshua Kelly The new word on the street to describe Sandy is "Frankenstorm." It's been given that name for two reasons: the sheer nature of the storm and also the date that it’s going to be impacting the East Coast - right around the Halloween period. Sandy is on a crash course to hit one of the United States most populated places which could create a large amount of chaos in the region. A state of emergency has been declared by many states in...
NASA’s Supersonics Project will embark on its latest effort to soften sonic booms when a NASA F/A-18 aircraft takes to the air in a project called Farfield Investigation of No Boom Threshold, or FaINT, beginning in late October. As the latest in a continuing progression of NASA supersonics research projects aimed at reducing or mitigating the effect of sonic booms, FaINT is designed to enable engineers to better understand evanescent waves, an acoustic phenomenon that occurs at the very...
In a tropical cyclone, strong uplift of air pushes the tops of thunderstorms high into the troposphere. When that strength wanes, the cloud tops drop and become less cold. That's because the higher you go in the troposphere, the colder it gets. NASA satellite infrared data has revealed that Tropical Storm Tony's cloud top temperatures are warming and the storm is weakening. The Atmospheric Infrared Sounder (AIRS) instrument aboard NASA's Aqua satellite captured infrared imagery of Tropical...
NASA's Aqua satellite watched from space as Somalia in the Horn of Africa experienced a landfalling tropical cyclone on Oct. 25. On Oct. 25, NASA's Aqua satellite saw Tropical Storm Murjan begin to make landfall in eastern Somalia, just south of Cape Guardafui. Cape Guardafui is located in the northeastern Bari province and forms the geographical point of the Horn of Africa. On Oct. 25, 2012 at 0720 UTC (3:20 a.m. EDT) the Moderate Resolution Imaging Spectroradiometer (MODIS) instrument...

[ Watch the Video: High Speed Video Of Shock Diamond ] April Flowers for redOrbit.com - Your Universe Online A supersonic jet of material that looks amazingly similar to the afterburner flow of a fighter jet is blasting over two million light-years from the center of a distant galaxy. The big difference, however, is that the jet engine responsible for this material is a supermassive black hole and the material is moving at nearly the speed of light. A new study, published this past...
[WATCH VIDEO: A Meteor Shower From Halley's Comet] Lawrence LeBlond for redOrbit.com - Your Universe Online Throughout the year Earth’s denizens are offered a number of good opportunities to witness meteor showers illuminating the night skies, with streaks of white lights racing across the upper atmosphere at lightning speed. Some of these seemingly heavenly showers, such as the late-April Lyrids, the Perseids of mid-August, and the often-spectacular Leonids, which arrive in November,...

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...
