# Quick Answer: What is the wind speed at 30000 feet?

Contents

For reference, the average speed of this type of aircraft at cruising altitude (around 30,000 to 35,000 feet) is 561 mph, according to TopSpeed.com.

## How fast is the wind at high altitude?

Yet, the wind speed at this altitude is not as fast as they are at 20,000 – 50,000 feet above the earth. Winds move faster and more consistent the higher one climbs, maxing out in the jet streams. At this altitude, the winds exceed 57 MPH and at times reach 247 MPH.

## At what height does wind stop?

“Generally, the higher you go, you lose what is called the friction layer,” where friction with the surface of the earth itself slows the wind somewhat, Mr. Searles explained. This happens at 30 to 100 feet, depending on the terrain and vegetation.

## How do you calculate wind speed at altitude?

Alternatively another formula can be used to calculate wind speed at various height. V=(Vt/k). ln(h/Z0). where, Vt is the friction velocity, V is the wind speed at height ‘h’, ‘k’ is the Karman constant (~0.4) and Z0 is the roughness length.

## How fast can a plane fly in a jet stream?

The wind speeds are greatest where temperature differences between air masses are greatest, and often exceed 92 km/h (50 kn; 57 mph). Speeds of 400 km/h (220 kn; 250 mph) have been measured. The jet stream moves from West to East bringing changes of weather.

## Is wind speed higher at higher altitude?

Wind speed increases with increasing height above the ground, starting from zero due to the no-slip condition. Flow near the surface encounters obstacles that reduce the wind speed, and introduce random vertical and horizontal velocity components at right angles to the main direction of flow.

## Do higher elevations get more wind?

Going up in altitude, the pressure gradient between the warm air and the cold air increases with height. … The influence of this friction is less with height above the ground, thus the wind speed increases with height. A third reason is due to air density.

## Where is wind strongest?

For nearly sixty-two years, Mount Washington, New Hampshire held the world record for the fastest wind gust ever recorded on the surface of the Earth: 231 miles per hour, recorded April 12, 1934 by Mount Washington Observatory staff. The Mt.

## Why does wind speed decrease at night?

The wind speed tends to decrease after sunset because at night the surface of the Earth cools much more rapidly than does the air above the surface. … During the day it is very easy for the air to mix and cause surface gusts. If there is a low pressure area or storm in the region the winds will blow day or night.

## Why is wind speed faster over water?

The winds, whether generated by a coastal storm or an afternoon summer sea breeze, blow faster over the ocean than over the land because there is not as much friction over the water. … The oceans do not have these impediments, which impart friction, therefore; the wind can blow at a greater velocity.

## Does 10000 feet have wind?

10,000 m (32,800 ft), where average wind speeds can exceed 45 m/s (equal to 162 km/h or 100 mph). … From these heights, wind speed and energy decrease moving towards the ground, the layers of air giving back heat through friction between them and with the orography of the Earth’s surface.

## How is wind speed measured?

Wind speed is normally measured by a cup anemometer consisting of three or four cups, conical or hemispherical in shape, mounted symmetrically about a vertical spindle. The wind blowing into the cups causes the spindle to rotate. … Calibration corrections are applied to the measured wind speed.

## How do you calculate average wind speed?

AverageWindSpeed = SQRT(EW_Average² + NS_Average²) //Simple Pythagorean Theorem. Now you will have an Average Wind Speed and a direction between 0-360°. In this Case the reported North/South Vector is reversed. When you are calculating the averages you will have to reverse the radians by *-1.

## Why do planes not fly over the Pacific?

The primary reason airplanes don’t fly over the Pacific Ocean is because curved routes are shorter than straight routes. Flat maps are somewhat confusing because the Earth itself isn’t flat. Rather, it’s spherical. As a result, straight routes don’t offer the shortest distance between two locations.

## Do you fly faster against Earth Rotation?

At the equator, the Earth spins about twice as fast as a commercial jet can fly. That rate slows the closer you get to the poles, but regardless, it’s always going to be faster than a plane.

## Why is it quicker to fly west to east?

Jet streams are, at their most basic, high-altitude air currents caused by atmospheric heating and the inertia of the earth’s rotation—and they’re the reason why flights from west to east are faster than the same route traversed in the opposite direction.
