May 28, 2023 · Sample Application. While driving north a distance of 500 km, your car thermometer shows the outside air temperature decreasing from 20°C to 10°C. How does the theoretical geostrophic wind change with altitude? Find the Answer. Given: ∆y = 500 km, ∆T = 10°C – 20°C = –10°C, average T = 0.5· (10+20°C) = 15°C = 288 K. Find: ∆U g /∆z = ? (m s –1)/km.
In meteorology, wind speed, or wind flow speed, is a fundamental atmospheric quantity caused by air moving from high to low pressure, usually due to changes in temperature. Wind speed is now commonly measured with an anemometer.
Apr 27, 2024 · Wind is nothing more than the movement of air molecules from one place to the next. The direction and speed of the wind represents the balance between three basic forces acting on it: the pressure gradient, the Coriolis force, and surface friction.
This short film could be useful in providing a simple explanation of how wind is formed, and could be used when introducing the concept of air pressure.
Definition. Wind speed is the rate at which air moves past a specific point, typically measured in meters per second (m/s) or kilometers per hour (km/h).
May 1, 2010 · Wind speed is measured in m/sec or km/h using an anemometer. Sailors may record the wind speed in knots. The Beaufort scale can be used to estimate the wind speed by observation.

What factors affect wind speed?
Wind speed is the rate at which air moves across a surface, typically measured in units like meters per second or miles per hour. It is a crucial factor in aeolian processes, affecting the erosion and transportation of sediment, as well as the formation of various landforms shaped by wind action.
