A barometer measures atmospheric pressure
a barometer
Barometric pressure and baker's dozen are units of measure that begin with the letter b.
Atmospheric (or barometric) pressure. By measuring this you are able to predict short term changes in weather.
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.
hg is a measurement of Vacuum measured in Inches of Murcury.
As the weather was changing, the barometric pressure continued to rise.
Hi Falling barometric pressure means the atmosphere at the barometer is becoming less heavy. It also generally means a storm of some sort is coming with inclement weather. Here's a link to use for using a barometer and clouds to forecast the weather: http://web2.iadfw.net/danb1/clouds.htm
A barograph measure the amount of weight in the air.
Barometric pressure is caused by the weight of the air pushing down on the Earth's surface. It is influenced by factors such as temperature, altitude, and weather patterns. Changes in barometric pressure can indicate changes in weather conditions.
I do not have real-time data on barometric pressure. You can check the current barometric pressure in Chesapeake, VA by using a reliable weather website or app.
Falling barometric pressure usually indicates wet weather is on the way.
Barometric pressure is often abbreviated as "BP" in meteorology and scientific contexts.
