Thesehave been recorded over a long period of time. In general,the lengths of the arrows indicate how often the winds camefrom that direction. The longer the arrow, the more often thewinds came from that direction. When the arrow is too longto be printed in a practical manner, a number is indicated.The number in the center of the circle shows the percentageof the time that the winds were calm. The lengths of thearrows plus the calms number in the center add up to 100percent.
