Air pressure is the weight of the air around us. When there is a period of low pressure, a barometer detects this and displays it with the needle. This reading is showing the weight of the air. It normally rains during a period of low pressure, so if the needle on the barometer is pointing to low pressure or rain, you can predict what the weather will be like in the following days. Hope this answers your question.

If Torricelli had drilled a little hole at the top of a glass tube holding his mercury column what would have happened to his barometer?
He would not have had a barometer. He would have had a glass tube stuck into a bowl of Mercury, with nothing in it. Because once the hole was made the vacuum would be gone and the mercury would fall back down to the bowl.It takes the vacuum in the tube to create a barometer.
