RE: Winds At 30-35.000 Feet #10496645 BY Buff - Wed Nov 22, 2000 11:19 am It isn't so much winds as windshear that creates high altitude clear air turbulence, or the rate of change of windspeed/direction over a given distance. The Tropopause is the layer where the standard lapse rate (about 2C/1000') has stabilized ( Approx -54C) and is steadystate the higher you go until the thermosphere when the temp actually starts climbing as you gain altitude. Since wind speed generally increases with increasing height, users should expect to see more frequent orange to red colors at high altitudes. 05:56 PM Eastern, National Centers for Environmental Prediction, N A T I O N A L W E A T H E R S E R V I C E, National Oceanic and Atmospheric Administration. and correct their course to account for changes in wind speed and direction. In a thunderstorm, television weather reporters might speak about sustained winds of 50 kilometers per hour (31 mph) with gusts as high as 100 (62 mph). The fastest wind speed not related to tornadoes ever recorded was during the passage of Tropical Cyclone Olivia on 10 April 1996: an automatic weather station on Barrow Island, Australia, registered a maximum wind gust of 408 km/h (220 kn; 253 mph; 113 m/s). The number has entered aviation lexicon as the catch-all height at which most aircraft travel from A to B. The temperature low is +26C and the high is +28C. 4.3 out of 5 stars 740 ratings. The average wind velocity ranges between 10 m/s to 20 m/s for an altitude between 3000 m and 8000 m [17]. This means that aeroplanes usually fly between 5 to 7 miles up in the air. Contacts.

Hub heights of modern 600 to 1,500 kW wind turbines are usually 40 to 80 metres, however. Areas with annual average wind speeds around 6.5 meters per second and greater at an 80-m height are generally considered to have a wind resource suitable for wind development. A weather balloon launched by the National Weather Service office east of New York City in Upton, New York, at 7 p.m. EST Monday night measured 231-mph winds at the 250-millibar pressure level in the atmosphere, or about 35,000 feet above the surface. Wind shear is best described as a change in wind direction or speed over a short distance. From what I understand, you would use a power law type relationship to model the wind speed within the atmospheric boundary layer (the height of which I'm not quite sure how to determine, but understand to be somewhere on the order of 1 km). Average annual wind speed (miles per hour and kilometres per hour) City MPH KPH; Atlanta, Georgia: 9.1: 14.6: Austin, Texas: 8.5: One of the central reasons behind aircraft altitude is that, as the air gets thinner with every foot climbed, planes The biggest reason for this altitude lies with fuel efficiency. This process would raise the temperature of the air to 130 F if air conditioners were not used to extract heat from the air. Just enter a wind speed measured at a . You will notice that going Eastbound, the groundspeed will flunctuate around 75 mph from one moment to the next. Beautiful shots taken while the sun is below the horizon, Accidents About WINDExchange V ector functions are used to average wind direction and can be used to compute a type. Since wind speeds tend to be pretty variable over time, I assume this would give the most accurate wind speed for the most important flight regime. Why Do Planes Fly At 35,000 Feet?

During most of the year, users can easily locate the "jet stream" by viewing the chart around 36,000 feet (FL360) and finding the ribbon of fastest-moving air. Use these tools to get aviation weather forecasts for U.S. airports, as well as to download the latest Terminal Area Forecast (TAF) report. Average wind speed and peak gust speed in meters per second (15-minute values) measured at 10 meters above the ground. 5280 feet = 1 mile 30000 feet / 5280 feet = 5.682 miles (rounded to third decimal). 3. Interval. The jet stream is a river of fast-moving air that separates cold air masses to its north from warm air masses to its south and often acts as a steering wheel for upper-level low-pressure systems. Sometimes this type of windshear generated turbulence extends to lower (<15,000') levels. The strongest jet streams are the polar jets around the polar vortices, at 9-12 km (5.6-7.5 mi; 30,000-39,000 ft) above sea level, and the higher altitude and somewhat weaker subtropical jets at 10-16 km (6.2-9.9 mi; 33,000-52,000 ft).
