* The weather scenarios that describe the {{Wikipedia|air mass|airmasses}} around your starting position, like reading a {{Wikipedia|Weather map|weather map}} around a position, are the ''actual simulation''. The weather changes as you move, or with time. Weather simulations are driven by terrain shape and surface materials, as well as other things like sun light. Enable ''Weather > Advanced settings > Terrain presampling'' and ''terrain effects'' (may cause slowdown in extremely old CPUs). The results of each scenario depend on the terrain around you. Simulated scenarios: core high pressure region (fair weather), high pressure region, border of a high pressure region, border of a low pressure region, low pressure region, and warm sector. You can tell which ones these are as ''Weather > Advanced settings > Tile selection'' is automatically set to ''realistic weather''. | |||
* "''Live data''" (live METAR) is not a simulation. No live weather service is - at any location you get weather belonging to one time of day, one day, one season, one long-term weather pattern like drought. Simulate another time of day, and it's wrong. Rare weather is unlikely when you fly. METAR data is also lacking and imperfect. | |||
* You can press "''Apply''" to get a new set of values for randomised properties. Atmosphere state is very complex. There are many different possibilities for scenarios that describe airmasses around you. There are way more properties than is presented in the UI, or can be presented without people accidentally making physically impossible combinations. These properties are randomised at each time AW starts. | |||
* Use ''Advanced settings > Temperature offset'' with scenarios to simulate higher or lower temperatures. This is the only way to simulate winter. Rainy scenarios produce snow-fall as appropriate. | |||
* Use ''[[Weather#Snow and rain on ground|Environment settings]]'' for rain on the ground, or adjusting snow deposits - these depend on history of weather, not weather at any instant. | |||
