This wind wave model generates forecasts of wave conditions through the use of wave-action conservation and the wind-field forecasts (from weather forecasting models). [1] In continuum mechanics, wave action refers to a conservable measure of the wave part of a motion. [2] For small-amplitude and slowly varying waves, the wave action density is ...
On average Edmonton receives 2,299 hours of bright sunshine [14] per year and is one of Canada's sunniest cities. [4] The summer of 2006 was a particularly warm one for Edmonton, as temperatures reached 29 °C (84 °F) or higher more than 20 times from mid-May to early September.
To relate radar timing to distances traveled by radar energy, the speed is used to calculate it. With speed of radar waves at approximately the speed of light in vacuum or 299,792,458 metres per second (300 m/μs; 984 ft/μs) and nautical mile at 1,852 metres (6,076 ft), the delay per nautical mile until the wave return is calculated as:
In general, wave quality for surfing is usually better with less wind. If there is wind, wave quality is better if the wind is blowing gently offshore (away from the coast, towards the water.) This offshore airflow helps to hold up the face of breaking waves slightly longer, allowing a surfer to have more time to maneuver on the face of the ...
An anemometer is commonly used to measure wind speed. Global distribution of wind speed at 10m above ground averaged over the years 1981–2010 from the CHELSA-BIOCLIM+ data set [1] In meteorology, wind speed, or wind flow speed, is a fundamental atmospheric quantity caused by air moving from high to low pressure, usually due to changes in ...
On February 5, Edmonton recorded a temperature of −32.3 °C (−26.1 °F) and a wind chill of −37 °C (−35 °F), [16] as a result of the "polar vortex" making its way west. [ 17 ] [ 18 ] Extreme cold carried into March, with temperatures hitting −31.2 °C (−24.2 °F) in Calgary on the second, [ 19 ] and −38.6 °C (−37.5 °F) in ...
The light-second is a unit of length useful in astronomy, telecommunications and relativistic physics. It is defined as the distance that light travels in free space in one second , and is equal to exactly 299 792 458 m (approximately 983 571 055 ft or 186 282 miles ).
Photons were detected 1.7 seconds after peak gravitational wave emission; assuming a delay of zero to 10 seconds, the difference between the speeds of gravitational and electromagnetic waves, v GW − v EM, is constrained to between −3 × 10 −15 and +7 × 10 −16 times the speed of light. [30]
