The correct answer is A. An updraft occurs when warm air from the south rises.
Explanation:
Updrafts are a common weather phenomenon. Localized regions of warm or cold air will exhibit vertical air movement. A hot air bag will usually be less dense than the surrounding region and then this bag will rise until it finds regions where the air will be at the same temperature or density. The converse of this phenomenon is known as downdraft. The vertical movement of large volumes of air is the main cause of thunderstorms and is generated by the effects of atmospheric convection.
