    Study Notes

    Wind Measurement and Wind Vectors

    • Wind vane and anemometer are used to measure wind speed and direction.
    • Wind direction is typically listed in degrees on weather maps.
    • Winds are named from the direction they come from, not the direction they go to.
    • West wind comes from the west and goes to the east.
    • Wind direction can vary based on local systems passing.
    • Anemometer measures wind speed using a cup or flywheel.
    • Anemometer is a term that should be known and it measures wind speed.
    • Wind vectors have direction and magnitude, represented by arrows of different sizes.
    • Wind vectors can be seen on traditional weather maps.
    • Wind is driven by temperature and pressure differences.
    • Air flows from areas of high pressure to areas of low pressure.
    • Coriolis force causes winds to curve to the right in the northern hemisphere and to the left in the southern hemisphere.
