The main components are PC817 optocoupler, and of course the hacked fan. Values for the roughness index range from 0.01 for flat landscapes to 2.0 in town centres. The instruments used to measure wind are known as anemometers and can record wind speed, direction and the strength of gusts. Another measure is the Beaufort scale consisting of integer numbers from 1 to 12. Enhanced Fujita Scale estimated wind speeds: 166 to 200 mph. Ripples with the appearance of scales are formed, but without foam crests. Wind speed is measured by using a scale of 0-12 based on what you can see happening around you.

An earlier version called the Saffir-Simpson Hurricane Scale took into account storm surges, central pressure, and wind speeds when determining damage. A Fujita scale measures tornadoes. A typical wind vane has a pointer in front and fins in back. 1 Light Air 1 to 3 mph Direction of wind shown by smoke drift, not by wind vanes. A wind sensor designed to measure wind speed and direction. The cups catch the wind and produce pressure difference inside and outside the cup. Depending on the ability of students, it is probably sufficient that they recognize calm air, and gentle, moderate, and strong breezes. The Beaufort Scales are used to measure wind speed.

Crests have a glassy appearance and do … Average wind speed—The mean wind speed over a specified period of time. Another scale is commonly used to measure wind speed and is known as the Saffir-Simpson scale. Winds in the most extreme tornadoes can be over 300 mph (500 km/h). Tornadoes are classified using a scale called the Fujita Scale, which measures both wind speed and the damage it causes. Other scales are often used in other areas of the world. It was originally developed in 1806 by Sir Francis Beaufort. When the wind blows harder, the cups of the anemometer turn faster and that is the higher reading on the meter.
