Beaufort Wind Force Scale

Instructions on determining wind force by observation.

This poster cites the official description of each wind force, but goes beyond that to show how it impacts both land and sea. Illustrations show increasingly powerful winds and waves systemically destroying a summer beach cottage and tearing off large sections of the cliff, severely eroding the shoreline. Used to determine wind speed based solely on observation. Essential reference chart for meteorologists, seamen or anyone else who wants or needs to know how to identify weather conditions.
