I know this is going to get me in trouble. Perhaps we have it backwards...
The "environment" is a not an active computing element, it merely exists and does not care about the objects in it. It effects the objects but has no knowledge of the objects. rather the objects sense the environment and its state based on their location in the environment. (We can argue that the objects in turn change the enviroment, but that is akin to computing the center of mass of the sun/earth system.) Sooo.. Seems we should treat the weather data as a set of points equally spaced and distributed that contain the relevant information and define a 3D field. Any object flying through the field could then based on its location select two or more data points and using whatever algorithm desired compute a local condition. The field could be static, homogeneous, cyclical, monotonic, whatever. The object would only care about its location in the field, not how the field is created, updated, or rates of change. A seperate application/thread would then be responsible for creating and updating the field in whatever fashion deemed appropriate. The field could be organized as a set of volumes and managed in a manner similar to the scenery tiles. Volumes would contain associated METAR stations or whatever for computing data points which would then be merged with the existing field.
