DCS Reference: Dynamic Weather
Much like custom labels, DCS' weather system is a heavily obfuscated and largely opaque, but also very capable part of the simulation. The biggest problem with is that, while there is a dynamic weather tab in the mission editor, it exposes roughly none of the capabilities of the system and trying to use it via the editor relies entirely on random chance to create some desired effect using parameters that simply cannot produce them.
A complete lack of control combined with a being completely unfit for purpose is a great way to dissuade the aspiring mission maker from ever using the dynamic weather system, instead relying on the much more immediate and obvious static weather. This guide aims to demystify the capabilities of the dynamic weather available in DCS. With only a little bit of practice, situations like the one depicted at the top of the page: gentle snow falling in light breezes from heavy clouds, with clear skies on the horizon. This is a weather state that simply cannot be achieved through the use of the mission editor alone.
