Senses Wind Speed?
|
|
Wind Speed and Direction are usually difficult to measure due to their variance over short distances. Wind Speed is typically measured via a rotating propeller or cup (anemometer) device.

Senses Wind Direction?
|
|
Wind Speed and Direction are usually difficult to measure due to their variance over short distances. Wind direction is typically measured with a wind vane or aerovane and is reported as the direction winds are coming from.

Measures Barometric Pressure?
|
|
Atmospheric pressure at the Earth's surface is one of the keys to weather. Air in a high pressure area compresses and warms as it descends. The warming inhibits the formation of clouds, meaning the sky is normally sunny in high-pressure areas. Just the opposite occurs within an area of low atmospheric pressure. Barometric pressure is typically measured with a mercury or aneroid barometer.
