This is when a warm front meets a cold front.

Droughts and prostrated heat are classic conditions for causing bushfires.A man-made condition that causes bushfires is sheer idiocy. Bushfires are, unfortunately, commonly caused by man's activities, whether arson or unintentionally lighting the fires such as by tossing cigarettes out of car windows, or not extinguishing campfires properly.High winds, coupled with dry air, can cause bushfires. Gusting winds cause faulty power lines to spark and arc, which easily ignites the vegetation into bushfires.
