Hand-Drawn Analyses. The human hand is one of most important instruments in predicting tornadoes. Studies of surface and upper air data, which are drawn on maps, help forecasters to see patterns in the storm that may indicate cyclonic weather.
Anemometer: Anemometer, device for measuring the speed of airflow in the atmosphere, in wind tunnels, and in other gas-flow applications. Most widely used for wind-speed measurements is the revolving-cup electric anemometer, in which the revolving cups drive an electric generator. The output of the generator operates an electric meter that is calibrated in wind speed. The useful range of this device is approximately from 5 to 100 knots. A propeller may also be used to drive the electric generator, as in the propeller anemometer. In another type of wind-driven unit, revolving vanes operate a counter, the revolutions being timed by a stopwatch and converted to airspeed.
