Document Summary
Measuring the wind: anemometer- measures wind speed, wind vane (or weather vane)- measures wind direction with a fin mounted on a vertical rod, aerovane- combines a wind vane and anemometer into a single instrument. The beaufort scale: the beaufort wind force scale (or beaufort scale) is used to rank wind speeds, based on wind"s observed effects on objects, rather than on directly measured wind speeds. Wind direction: winds are named for the direction from which they originate, ex. A wind from the west is a westerly wind. Naming the wind: three basic categories of wind names, names using compass or degree headings, names in relation to water and land in coastal areas, names based on prevailing direction of wind. Portraying wind on a map: three ways to portray wind on a map are, wind barbs, wind vectors, streamlines. Measuring air pressure: barometer: an instrument used to measure air pressure (mercury and aneroid barometers)
