Force 4 wind speed
http://pressbooks-dev.oer.hawaii.edu/atmo/chapter/chapter-10-atmospheric-forces-and-wind/ WebThe Beaufort scale has 17 levels of wind force. “0” describes conditions that are so calm that smoke rises vertically. “12” describes a hurricane, and “13-17” are reserved only for tropical typhoons, the most powerful and potentially destructive wind systems. An anemometer is a device for measuring wind speed.
