If you live in the U.S., to find the barometric pressure for your city, another municipality or a national park or other attraction on a given day in history, visit the National Weather Service online. Type your zip code or city, state into the search box in the upper left of the screen. The land and water bodies also heat up the air, making it less dense. Here, hot air increases and creates low pressure over that area and cold air sinks and creates a region of high pressure. Air, like all fluids, likes to maintain equal pressure. To do so, cold air from high-pressure areas flows into regions of lower pressure.Atmospheric pressure is the total weight of the air above unit area at the point where the pressure is measured. Thus air pressure varies with location and weather . If the entire mass of the atmosphere had a uniform density equal to sea level density (about 1.2 kg per m 3 ) from sea level upwards, it would terminate abruptly at an altitude of ...Current Barometric Pressure Map for Connecticut.
