The current version 0.7 supports placement of effect volumes for visibility, rain, snow, turbulence and thermal lift, as well as interpolation of visibility, pressure, temperature and dewpoint between weather stations. It has a variety of 40x40 km weather tiles with layered and non-layered clouds and weather effects, thunderstorms, external models of precipitation and (with a CVS patch) also support for gliders, i.e. it creates thermals below convective clouds. Automatic weather tile reloading for long-range flights is implemented, both in a simple 'repeat-tile' function and a set of tile selection rules to simulate the long-range change of real weather. Terrain presampling algorithms automatically adjust the cloud placement over elevated terrain. As an example, the picture shows Nimbostratus clouds with precipitation seen from outside.

Terrain presampling algorithms automatically adjust the cloud placement over elevated terrain.
