Isotach

Isotachs are maps that use isolines to connect points that have the same wind speed. The term Isotach can be used interchangeably with Isoline when the map is representing wind speed.


The map shown is an Isotach Map displaying wind speeds over the North Pole. The map connects the points of equal wind speed. The lines are enhanced with different color shading. White and Purple indicate a low amount of wind speed while moving up the color spectrum to red indicates a high amount of wind speed.
