Not sure what exactly you were trying to do. When you run Advanced Weather, it always uses its own wind model - it can't know what you entered in the Basic Weather config dialog and it doesn't care - we're not so far along the road to a merged weather system (if you were running Basic weather and it was ignoring its own config, that'd be a bug though). Advanced Weather has a few wind modes - constant (wind is the same everywhere), constant in tile (wind is the same in each chunk of 40x40 km, but may change between tiles), aloft interpolated (wind is interpolated based on the values entered in the wind dialog which is visible when you press 'show winds' and aloft waypoints (wind is interpolated based on a set of vectors both in altitude and in position - this is *very* cumbersome to enter manually and intended to run with online weather). Even the aloft interpolated modes don't allow you to select an arbitrary wind profile though, the low altitude interpolation altitude values are always 0, 5000 ft and 10000 ft (this choice made following advice from TorstenD who had plans to get online aloft winds automatically in this format, something which isn't implemented yet), so you can only have a linear profile between these altitudes. The system doesn't allow you to specify wind conditions in the boundary layer, because it wants to compute them itself. You get a boundary layer which adapts to terrain roughness and local elevation, for instance there is no boundary layer slowdown of winds at mountaintops, and significantly less on upper mountain slopes than on the ground (which is somewhat important for ridge lift to work properly), boundary layer slowdown is far less pronounced over open water than in mountain terrain,... I suspect you were interested in specifying especially this region? In case you want to do something to the boundary layer computation, you'd have to dig into the code, this can't be done from config.

Soaring feels very realistic! Thanks. There's a lot of real life glider flying experience behind the convective cloud system and the thermals :-) If I find the time (which doesn't happen too often) I enjoy going cross-country with the ASK-13 very much. Like in real life, there are all sorts of surprises which can happen, and I always find mountain-soaring very exciting. Still need to implement that wave lift model at some point...
