Factors Affecting Wind Speed
Wind speed is affected by a number of factors and situations, operating on varying scales (from micro to macro scales). These include the pressure gradient, Rossby waves and jet streams, and local weather conditions. There are also links to be found between wind speed and wind direction, notably with the pressure gradient and surfaces over which the air is found.
Pressure gradient is a term to describe the difference in air pressure between two points in the atmosphere or on the surface of the Earth. It is vital to wind speed, because the greater the difference in pressure, the faster the wind flows (from the high to low pressure) to balance out the variation. The pressure gradient, when combined with the Coriolis Effect and friction, also influences wind direction.
Rossby waves are strong winds in the upper troposphere. These operate on a global scale and move from West to East (hence being known as Westerlies). The Rossby waves are themselves a different wind speed from what we experience in the lower troposphere.
Local weather conditions play a key role in influencing wind speed, as the formation of hurricanes, monsoons and cyclones as freak weather conditions can drastically affect the velocity of the wind.

Famous quotes containing the words wind speed, factors, affecting, wind and/or speed:
“The wind speeds her,
Blowing upon her hands
And watery back.
She touches the clouds, where she goes
In the circle of her traverse of the sea.”
—Wallace Stevens (1879–1955)
“I always knew I wanted to be somebody. I think that’s where it begins. People decide, “I want to be somebody. I want to make a contribution. I want to leave my mark here.” Then different factors contribute to how you will do that.”
—Faith Ringgold (b. 1934)
“It is a relief to read some true book, wherein all are equally dead,—equally alive. I think the best parts of Shakespeare would only be enhanced by the most thrilling and affecting events. I have found it so. And so much the more, as they are not intended for consolation.”
—Henry David Thoreau (1817–1862)
“Absence cools moderate passions, and inflames violent ones; just as the wind blows out candles, but kindles fires.”
—François, Duc De La Rochefoucauld (1613–1680)
“If it be aught toward the general good,
Set honor in one eye, and death i’th’ other,
And I will look on both indifferently;
For let the gods so speed me as I love
The name of honor more than I fear death.”
—William Shakespeare (1564–1616)
