New Doppler Radar Will Measure Rain And Wind On This Summer's HS3 Mission
2013-08-01 09:29:29

The autonomous and compact High-altitude Imaging Wind and Rain Profiler, or HIWRAP, a dual-frequency conical-scanning Doppler radar, will hang under the aircraft's belly as it flies above hurricanes to measure wind and rain and to test a new method for retrieving wind data.

Researchers at the Woods Hole Oceanographic Institution have calculated the flow rate of the BP Macondo well to be about 57,000 barrels of oil per day, totaling close to 5 million barrels of oil and nearly 100 million standard cubic feet per day of natural gas released from April 2010 to July 2010.

Whether they know it or not, anyone who's ever gotten a speeding ticket after zooming by a radar gun has experienced the Doppler effect – a measurable shift in the frequency of radiation based on the motion of an object, which in this case is your car doing 45 miles an hour in a 30-mph zone.

What if the speed of light is a constant only most of the time? What if gravity sometimes pushed instead of pulled? Scientists are increasingly asking what would seem like far-out questions regarding the laws and rules of physics after discovering conditions and materials where the rules don't quite apply. Take the Doppler effect.

Doppler Effect -- The Doppler effect is the apparent change in frequency or wavelength of a wave that is perceived by an observer moving relative to the source of the waves. For waves, such as sound waves, that propagate in a wave medium, the velocity of the observer and the source are reckoned relative to the medium in which the waves are transmitted. The total Doppler effect may therefore result from both motion of the source and motion of the observer. Each of these effects is analyzed...
