If the barometric pressure drops suddenly, as it does often before a storm, and your sinus passageway is blocked, the higher pressure in the sinus will press on the bones surrounding it to cause a horrible headache. When your nose is stuffy, the inner linings of your nose are swollen, and the same swelling can shut the sinus passageway, preventing air pressure inside your sinus from changing to balance the pressure outside, and you can develop a sinus headache.

The volume of the container is increased.
Barometric pressure measures the weight of the air.
blood vessels constrict according to barometric pressure
Low and high pressure systems. Obviously if you have a Low pressure system the barometric pressure will get low. High pressure causes the barometric pressure to rise.
because of barometric pressure
When the barometric pressure rises it means calm fair weather is coming or is already occurring. When the barometric pressure falls it means foul weather is on the way such as rain and storms and clouds.
A hurricane has very low barometric pressure.
Barometric pressure goes down in a tornado.
A sudden decrease in barometric pressure is a sign that a storm is coming.
Yes, Barometric Pressure and Atmospheric Pressure are the same thing. Except one describes what Atmospheric Pressure would be measured in.
