Wind is slowest near the ground because of friction. You can see a small example of the friction effect by looking at the surface of a dusty car. The dust will not blow off even if the car is driven at high speed, because the air closest to the car's surface will be moving much more slowly than the car itself due to surface friction.

The strongest winds occur near the place in the atmosphere where the temperature stops dropping as you go higher, and starts to rise again. This is the tropopause, and the strong winds which occur there are known as jet streams. The causes of jet streams are complex, but, like all winds, are caused by air attempting to move from an area of high pressure (usually cold air) to one of low pressure (usually hot air).

Does wind speed change with altitude in a hurricane?

Yes, wind speed in hurricanes typically increases with altitude. This increase in wind speed with altitude is known as the wind profile within the hurricane, with the strongest winds typically found at higher altitudes in the storm's structure.


How is wind speed affected by altitude?

Wind speed generally increases with altitude. This is due to a decrease in surface friction and obstacles that slow down the wind closer to the ground. As air is less hindered by obstacles at higher altitudes, it can flow more freely and result in higher wind speeds.


What conditions are believed to be caused by el nino and effectively weakens hurricane in the atlantic ocean?

It is believed that El Niño produces wind shear, which is a change in the speed and/or direction of the wind with altitude.


What impact does increasing wind-speed have on wind chill?

Increasing wind speed increases the rate of heat loss from the body, making the air feel colder than it actually is. This results in a lower perceived temperature, known as the wind chill effect. The higher the wind speed, the stronger the wind chill effect.


Is a person jogging at 3 m s along wind an example of acceleration?

Yes, a person jogging at 3 m/s along the wind can be considered an example of acceleration if there is a change in velocity, such as increasing speed, changing direction, or experiencing a change in wind resistance. Acceleration is defined as the rate of change of velocity over time. If the jogger maintains a constant speed and direction, then there is no acceleration. However, if the wind affects their speed or direction, then acceleration occurs.


How can a wind turbine go faster?

A wind turbine can go faster by increasing the wind speed it is exposed to. This can be achieved by placing the turbine at a higher altitude, using larger rotor blades, or installing it in an area with stronger wind conditions. Additionally, regular maintenance and optimization of the turbine's components can help improve its efficiency and performance.


Does the speed of a bullet decreases as the altitude increases?

Yes, due both to gravity and wind resistance.


Average speed of a hot air balloon?

The average speed of a hot air balloon is typically between 5-10 mph. However, the speed can vary depending on the wind conditions and altitude.


Can fluctuation of wind cause a tornado?

Not directly. But changes in wind speed and direction in altitude, called wind shear, plays an important role in tornado formation.


What is effect of increasing wind speed on rate of evaporation?

In a wind turbine - does increasing the blade length or decreasing the blade length increases the speed of the turbine?

Decreasing the blade length will increase the rotation speed, and thus the turbine speed ( for constant wind speed ).
