These spectra are used to obtain the growth of the spectral components at various frequency bands for increasing wind and different values of fetch and current. The results indicate that the growth of these components is not monotonic with the frictional wind speed, but rather exhibits an '...
Wind- wind speed at specified height Temp- temperature at specified height RH- relative humidity at specified height WPD- Instantaneous Wind Power Density. Measure of power available in the wind: ½ρv3, where ρ is air density and v is wind velocity ...
Wind Shear:I knew going into the event days before that wind shear was going to be well beyond supportive for severe weather. Wind shear in this sense is defined as the wind speed difference between the surface and 1 kilometer in altitude. I looked in the lowest 1 kilometer of the atmosph...
Which I did. Only paddling against the wind and current, it took me two hours to return, as compared with the 30 minutes or so to paddle out. When I finally arrived in late afternoon back at Walker’s, I was still as stumped as before. Acting on a hunch, I continued on past the ...
Additionally, hourly values of near surface air temperature, dew point temperature, solar radiation, and wind speed data for the four selected years were retrieved to obtain hourly values of WBGT (see section above). In the climate change exercise, we studied a period by mid-21st century (...
(rudder boat, differential boat, airboat) and a sailboat. The boats are affected by waves, wind and water currents. To do that, we curently use UWsim for water surface modeling, we also loadHEC-RASoutput files with water speed of river and channel simulations. We simulate wind current with...

So far, so good. Christina Rose had handled fine during the 7-mile Hudson crossing to Croton Point. We’d travelled at a speed of 8-10 knots, with a gusty, 20-kt wind. It was bouncy, but manageable. Mully hadn’t enjoyed the trip. ...
Discipline starts every day when the first alarm clock goes off in the morning. I say 'first alarm clock' because I have three, as I was taught by one of the most feared and respected instructors in SEAL training: one electric, one battery powered, one windup. —Jocko Willink ...
The optimal wind stress of 0.1 N m−2 in the central CCS is equivalent to a wind speed of ~8.5 m s−1 (ref. 24), falling between optimal wind estimates of ~11.5 m s−1 for shelf productivity in a simple model17, and 5–6 m s−1 for pelagic fish recruitment25. ...
