We've seen wind turbines fit for backyards, balconies, even oceans- and now pioneering wind-power engineers are looking to take wind turbines to new heights15,000-30,000 feet in the air! The higher you get, the colder it gets, up until 40,000 feet. The average wind speeds indicated on this map are model-derived estimates that may not represent the true wind resource at any given location. Some Airliners.net is the leading community for discovering and sharing high-quality aviation photography. When we talk about wind, this is what's actually being measured. Both military and civil versions, Blimps / Airships This event seems to be a combination of an exceptionally strong jet stream and an improved observing system that captured it better than we might have in the past," said Bob Henson, meteorologist and climate blogger at Weather Underground.

Last Friday night, record-high wind speeds for that altitude were set in Las Vegas (206 mph) and Dodge City, Kansas (192 mph). It would actually be most efficient to be forever climbing, rather than plateau when reaching say, 35,000 feet, cruising altitude, as the weight of the aircraft decreases due to fuel usage and the air thins. Atmospheric air pressure drops at an average predetermined standard rate of _____ inch(es) of Mercury per one thousand feet of altitude gained.

Since the current simulation is in 3DOF, only the effect of headwind is included. On average, above the north pole at 30,000 ft, there is. For those who find rules of thumb useful, remember the "4-5 rule": observe that 4 is 20% less than 5 and that 5 is 25% more than 4. Therefore, do not expect Marlene; Dec 15, 2019; I gave the CD as a birthday present. The UAV manufacturers say "There's no weather up there": I expect if any of them are successful we'll learn a lot more about how much weather there isn't. This is the standard reported by the Remote Automated Weather Stations (RAWS) owned by land management agencies and used in the National Fire Danger Rating System (NFDRS). We'll be flying at a height of ten feet, going up to 12 and a half feet if we see anything big.". [Chorus 2] I said I've been better, I've been worse. "With the old radio direction finding system, wind observations for a flight such as this would have terminated at around 20,000 feet, owing to 'limiting angles' of the tracking system," Bill Blackmore of NOAA said in an email to weather.com.

The average temperature at 9,144 meters (30,000 feet) in the sky ranges between from -40 C to -57 C (-40 F to -70 F). What Is the Difference Between Airspeed and Ground Speed? Because the power in the wind has a cubic relationship to wind speed, a site with an average 15 mph wind speed contains nearly 100 percent more energy than a site with an average wind speed of 12 mph. The troposphere that is the atmospheric layer closest to the ground is home to most of the world's weather phenomenons. A typical day in mid-summer may show a value of All 1-hourly 3-hourly 6-hourly 12-hourly 24-hourly. 4.3 out of 5 stars 740 ratings.

The thin air creates less drag on the aircraft, which means the plane can use less fuel in order to maintain speed. All of these records date back to when weather balloons were first launched on a regular basis in the 1940s and 1950s. Areas with good exposure to prevailing winds and annual average wind speeds around 4 meters per second and greater at a 30-m height are generally considered to have a suitable wind resource for small wind projects.
