fDesc[0] = "A weather theme is a collection of meteorological data that Flight Simulator uses to render weather visuals (clouds, precipitation, fog) and modify an aircraft&rsquo;s flight model (temperature, wind, icing). The data is stored in a regular grid of weather observations where each observation affects an area of 256 square kilometers (16km on each side). Weather themes can contain a single observation or be as large as 64x64 grid cells. This means that you can create a rich, dynamic weather experience that covers an area of over a million square kilometers.<br /> <br /> This SDK describes how to create and distribute weather themes for Microsoft Flight Simulator 2004: A Century of Flight using a special theme creation tool.";
