Normal sea-level atmospheric pressure is
WebThe Earth's atmosphere exerts pressure on the surface. Pressure is measured in hectoPascals (hPa), also called millibars. Standard pressure at sea level is defined as 1013hPa, but we can... Web22 de jul. de 2024 · This is called the inverse barometer effect. The average sea level during a year is 0 cmPGA and the average air pressure is 1013 hPa. Since the air pressure normally varies between 950 and 1050 hPa during a year, the expected variation in sea level due to air pressure is between +63 cm and -37 cm around mean sea level.
