Why is there a calm before a storm?

1.03K views

So I live on the South West Coast of Ireland and tomorrow we are expecting to be hit by the tail end of Hurricane Lorenzo. If you stand outside tonight, there isn’t even a puff of wind, just deathly calm. It’s eerie out there. Similar to a tsunami, is it a bit like all the wind has been sucked out beforehand?

As warm, moist air is pulled into a storm system, it leaves a low-pressure vacuum in its wake. … That descending air becomes warmer and drier which is relatively stable, and once it blankets a region, it stabilizes that air in turn. This causes the calm before a storm.
