The highest sea-level pressure on Earth occurs in Siberia, where the Siberian High often attains a sea-level pressure above 1,050 hPa (15.2 psi; 31 inHg), with record highs close to 1,085 hPa (15.74 psi; 32.0 inHg).
When gravity acts on the air, the air exerts a force upon the earth called pressure. The typical pressure at sea level is 1013.25 millibars or 14.7 pounds per square inch. A millibar is a unit that is used to report the the atmospheric pressure.
The standard atmospheric pressure at the surface of the Earth is defined by international agreement as the average pressure at a latitude of 45°32′ and at a temperature of 0°C. At sea level, the standard atmospheric pressure is equal to 101.325 mb, or 1013.25 kPa.
24 maj 2024 · Under average sea level conditions the atmospheric pressure is 1013.2 millibars (29.92 inches of mercury). Average sea level pressure serves as the division between what we call "high pressure" and "low pressure" at the surface.
Map of global mean air pressure at sea level in July, where high-pressure centers are more pronounced, especially over the North Atlantic and North Pacific oceans. Near Earth’s surface, atmospheric pressure decreases with height at a rate of about 3.5 millibars for every 30 meters (100 feet).
19 paź 2023 · An atmosphere (atm) is a unit of measurement equal to the average air pressure at sea level at a temperature of 15 degrees Celsius (59 degrees Fahrenheit). One atmosphere is 1,013 millibars, or 760 millimeters (29.92 inches) of mercury. Atmospheric pressure drops as altitude increases.
27 kwi 2024 · At the highest peaks in the Himalayas, air pressure is only about one-third of the air pressure at sea level! That is why weakly adapted climbers choose to use bottled oxygen as a support. Meteorologists have a variety of ways to then visualize weather data, a map being the most common.
