XPLMBeginWeatherUpdate

XPLM_API void       XPLMBeginWeatherUpdate(void);

Inform the simulator that you are starting a batch update of weather information. If you are providing multiple weather updates, using this call may improve performance by telling the simulator not to update weather until you are done.

This call is not intended to be used per-frame. It should be called only during the pre-flight loop callback. You must call XPLMEndWeatherUpdate before you return from the callback; XPLMBeginWeatherUpdate in one callback and XPLMEndWeatherUpdate in a later callback, even within the same frame, is not permitted.
