A local weather system in contrast is one in which continuous changes from the weather at one location to the weather in a different location are simulated, i.e. weather phenomena are tied to a specific location. Needless to say, a local weather system is significantly more complicated to simulate than the present system. Below is a conceptual outline how a local weather system for FlightGear could be created using mainly existing technology and code. | A local weather system in contrast is one in which continuous changes from the weather at one location to the weather in a different location are simulated, i.e. weather phenomena are tied to a specific location.

'''Advanced Weather''' has had the capability to do a 3-dim interpolation of a windfield for years - you just need to had it the correct aloft information, and it rotates the wind with altitude and position. It's actually 4d, because it has also the ability to gradually fade interpolation vectors in and out. Since default METAR doesn't say anything about aloft layer, it tries to deduce how much the local boundary layer winds are reduced from the terrain topology, guesses the lowest aloft wind layer from there, then guesses higher aloft layers based on Coriolis deflection of winds and the generic strengthening of high-altitude winds. <ref> {{cite web | |||
