Step (knots) changes the number by which the levels of wind speed increment when you are
in streamlines mode. For example, if you have 10 entered in the Step box, the legend will
change to increments of 10 knots each, up to 140 knots. Entering 12 will produce increments
of 12 and a maxiumum of 168 knots.
The Height area contains a slider bar that allows you to change the height at which winds are
being measured. The range is from winds along the surface to a maximum of 42,000 feet, in
increments of 3,000 feet. Sliding the bar up or down will cause the system to automatically
display the winds for the new height.
The Surface level in the Height bar measures wind speed along the land or
water surface regardless of height above sea level; therefore, data will always
be present. However, with the other heights data will not appear if the land
surface is higher in elevation than the height selected.
Close closes the Wind Display menu, allowing you to use other menus while viewing wind data.
