Study Notes
Introduction to Wind Measurement and Wind Vectors
- Wind vane and anemometer are used to measure wind speed and direction.
- Wind direction is typically measured in degrees, with 0 degrees indicating north.
- Winds are named based on the direction they come from, not the direction they go to.
- The term "anemometer" refers to a device that measures wind speed.
- An anemometer typically uses a cup or flywheel mechanism to measure wind speed.
- Anemometers are commonly used in weather forecasting and can be found in weather maps.
- Wind vectors represent wind direction and speed, with the length of the line indicating wind speed.
- Wind vectors are often represented by arrows on weather maps.
- The pressure gradient force, temperature differences, and the Coriolis force contribute to wind speed.
- Air flows from areas of high pressure to areas of low pressure.
- The Coriolis force causes winds to curve to the right in the Northern Hemisphere and to the left in the Southern Hemisphere.
- Wind speed increases with larger pressure differences between high and low pressure systems.
