This is the trickiest part. We'll describe each setting singularly, and in what cases they can be used/will have effect. | This is the trickiest part. We'll describe each setting singularly, and in what cases they can be used/will have effect. | ||
''Wind direction'' and ''speed'' define ''the lowest aloft wind''. | ''Wind direction'' and ''speed'' define ''the lowest aloft wind'' in a height convenient to the atmospheric boundary layer thickness. If "terrain presampling" is disabled, the boundary layer thickness is 600 feet. The definition of the "wind direction" and "speed" has no effect in METAR tile mode (because AW deduces it from the METAR itself, which reports the ''ground'' wind) and/or when the wind model is ''aloft interpolated'' or ''aloft waypoint'' (because that wind is used instead - see below). Otherwise you can use it. | ||
''Gust settings'' are the happiest ones: they always work, immediately, no click needed, but if a new live METAR comes in (because you moved to a new area) they'll be overwritten. Their meaning should be self-explanatory. Note that gusts are only effective in the boundary layer, i.e. when close enough to the ground. | ''Gust settings'' are the happiest ones: they always work, immediately, no click needed, but if a new live METAR comes in (because you moved to a new area) they'll be overwritten.

Finally, the ''Wind Configuration'' dialog, reachable with the button at the bottom, is the one used by the ''aloft'' wind models. It should be self explaining, but remember to set at least one waypoint if you want to use ''aloft waypoints'' in non-METAR mode. Also, the value for level ''zero'' is not meant to be ground level, but the lowest aloft layer, i.e. the one just above the boundary layer. This dialog is especially uncomfortable with waypoints, because that mode is intended for use with [[Howto: Fetch live aloft data|live aloft wind data]], that someday might become available (again.) | Finally, the ''Wind Configuration'' dialog, reachable with the button at the bottom, is the one used by the ''aloft'' wind models.

Note that the boundary layer is always calculated, but is less realistic without terrain effects. | Note that the boundary layer is always calculated, but is less realistic without terrain effects. | ||
