Answer 1

Answer:

As the warm, moist air is pulled into a storm system, it leaves a low-pressure vacuum in its wake. The air travels up through the storm cloud and helps to fuel it. ... Warm, dry air is relatively stable, and once it blankets a region, it stabilizes that air in turn. This causes the calm before a storm.

Answer 2

Answer:

The rising warm air forms a partial vacuum, which pulls cold air from high above. That helps drive the rain down. But this partial vacuum also pulls in air from all sides of the storm front. Air moving away from the partial vacuum gets pulled back – so the area in front of the storm experiences a calm.
