Pressures are corrected at sea level to provide a standardized reference point for comparison and measurements. By referencing pressures to sea level, it allows for consistency in data collection and analysis, especially in fields such as meteorology, aviation, and engineering.
980 mb to 1045 mb (Those are the values for deep low-pressure systems and strong high-pressure systems). The average sea-level pressure is 1013 mb. The highest and lowest sea level pressures record are 1084 mb and 870 mb.
You're probably thinking of methane hydrate-clathrate.
They need to be adjusted for altitude, so that all stations report an equivalent sea level pressure. If the raw station pressures are mapped the synoptic features can be obscured by topography. The pressure in Amarillo is always lower than the pressure in Dallas because of the difference in altitude. By correcting both to sea level, significant information about state of the atmosphere can be seen.
Atmospheric pressure of 1.0 millibars is very low and typically found at high altitudes or in extremely dry conditions. It is not within the range of normal atmospheric pressures experienced at sea level.
No, altitude and sea level are not the same thing. Altitude is the distance of a location above sea level, while sea level is a specific level used as a reference point for measuring elevations. Sea level represents the average level of the ocean's surface.
Is named an ISOBAR. It is a line of equal air pressure, on a meteorological map .
Yes, if you lower the pressure to about 6.6 kPa (normal atmospheric pressure at sea level is around 101 kPa; you'd find pressures like this at an elevation of about 12 miles above sea level).

Low pressure and high pressure are not absolute. You find those pressures at any place. http://en.wikipedia.org/wiki/Atmospheric_pressure
above sea level

Water becomes a gas when it reaches the boiling point, which is 100 C at sea level. The boiling point is different at lower air pressures / higher elevations.
The lowest point in Hawaii is in the Pacific Ocean at sea level. what the heck!
False. The central sea level pressure of the strongest hurricanes typically falls below 900 mb, with some of the most intense storms approaching or even dropping below 900 mb. A central sea level pressure of around 500 mb would be exceptionally low and not something observed in hurricanes.
Well, sea level is the standard by wich other things are measured, so zero is the answer. Sea level is sea level. Compared to what?
