Difference between barometric and atmospheric
WebMar 29, 2024 · These barometric readings are crucial for weather forecasts and explaining weather conditions. As pressure decreases and increases, it is often an indication of temperature, moving air masses, and high & low … WebAs the density of the Earth’s atmosphere decreases, the average atmospheric surface pressure remains the same. As dictated by the equation P = ρ R m T, where P is pressure ρ is density, T is temperature, and Rm is the univeral gas constant divided by the molar mass, there should be a relationship between density and pressure.
