For the purposes of formal weather forecasting, wind speed is measured using an anemometer (see below). The wind pushes the cups in a circle, and the number of turns corresponds to the wind speed. One way to measure wind speed is by observing its effects on objects.

When the wind drops fine particles of silt and clay, it forms deposits called loess (Figure below). Loess can become a thick, rich soil. That’s why loess deposits are used for farming in many parts of the world.

Two features that form through wind deposition are sand dunes and loess deposits.

(2) : marked by strong wind or by more wind than usual a windy day. b : violent, stormy.

“High wind” with sustained speeds of 40 to 57 mph. Wind conditions consistent with a high wind warning. “A Moderate Threat to Life and Property from High Wind.” “Very windy” with sustained speeds of 26 to 39 mph, or frequent wind gusts of 35 to 57 mph.

Beaufort Wind Scale

As the Sun warms the Earth’s surface, it also warms the atmosphere. Warmer air in the atmosphere is lighter than colder air. As cold air moves in, it pushes under the warm air, causing the warmer air to rise. This movement of the air is what makes the wind blow.

​11 free things to do on a rainy or windy day

• 1 – Go for a walk. It’s not raining razor blades out there, so get rugged up.
• 2 – Fly a kite. Just for windy days.
• 3 – Play games.
• 4 – Treasure hunt.
• 6 – Talk.
• 7 – Cook.
• 8 – Get ‘creative’
• 9 – Have a nap.

Do not participate in any watermelon seed spitting competitions. Golf and Disc Golf, Tennis, boomerang throwing, and Soccer (really any sports) are frowned upon in the wind. Don’t set up an outdoor birthday party with balloons and table covers. You won’t be able to light candles either.

The reason turbines shut down like this is for safety – if the wind is too fast it can put major stress on the blades and mechanisms inside the turbine causing lots of friction and long term damage. It’s much safer to have the turbines stop and then start again when wind is a bit slower and safer.

Heavy winds are typically formed by atmospheric pressure variations, which cause gusts of air to rush in to fill low-pressure zones. Additionally, wind can result from heavy activity in the jet-stream high in the sky. Finally, large fronts of cold air can also provoke turbulence in the atmosphere.

The Short Answer: Gases move from high-pressure areas to low-pressure areas. And the bigger the difference between the pressures, the faster the air will move from the high to the low pressure. That rush of air is the wind we experience.

It is produced by the uneven heating of the earth’s surface by the sun. Since the earth’s surface is made of various land and water formations, it absorbs the sun’s radiation unevenly. Two factors are necessary to specify wind: speed and direction.

All wind is caused by the uneven heating of Earth’s surface, which sets convection currents in motion, Convection currents on a large scale cause global winds; convection currents on a small scale cause local winds.

In the atmosphere, as air warms it rises, allowing cooler air to flow in underneath. Along with the turning of the Earth, this movement of air creates winds. Winds, in turn, create surface waves on the ocean. Convection also plays a role in the movement of deep ocean waters and contributes to oceanic currents.

So in short, convection (rising air due to heat) lowers surface pressure creating a pressure gradient that tries to correct itself by having air move from higher pressure to the lower pressure area created by the rising air. This correction is wind.

Convection is the circular motion that happens when warmer air or liquid — which has faster moving molecules, making it less dense — rises, while the cooler air or liquid drops down. Convection is a major factor in weather. That current can result in wind, clouds, or other weather.

Convection – When warm, moist air near the surface rises to be above the heavier cool, dry air this is a form of heat transfer or convection. The rising motion typically cools the air. As the air cools, it reaches the dewpoint and all of the moisture in the air condenses– forming clouds.
