How do weather conditions typically affect artillery firing?

Weather conditions significantly affect artillery firing, particularly in terms of visibility and trajectory calculations. Visibility can be impacted by elements such as fog, rain, or snow, which can hinder the ability to accurately spot targets. Additionally, atmospheric conditions like temperature, humidity, and wind can alter the trajectory of the projectile. For instance, high winds can deflect rounds off course, and variations in air density due to temperature and humidity can affect the range and accuracy of artillery fire.

Moreover, artillery calculations must account for these weather factors to ensure precision. A comprehensive understanding of how specific weather conditions influence both the shooter’s ability to identify targets and the physics of the projectile's flight path is essential for successful artillery operations. Thus, the correct answer highlights the critical relationship between weather and effective firing, emphasizing the need for accurate trajectory calculations in varying conditions.
