Is atmosphere pressure the same as sea level pressure??

Answer 1

The atmospheric pressure measured at a location is called the station pressure. Sea level pressure is the hypothetical pressure that would be measured if that station was at sea level (it usually isn't). The sea level pressure for a site is computed from the station pressure and the temperature at a site. If the station is at an elevation above sea level, then the station pressure will be less than the sea level pressure at that site. The computed sea level pressure in many elevated locations will not accurately reflect the real pressure, this often results in "artificial" high pressure areas in regions like Colorado and Alaska.

I have a slight quibble with Arasan's answer, which is correct for the most part: the sea level pressure is not always greater than the station pressure--specifically this is not true if the barometer is below sea level. I live in California, where this correction has to be applied to a number of stations around the state.

Answer 2

If a place is situated at sea level, then the atmospheric pressure over that place(usually called as station level pressure) will be equal to the sea level pressure.On the other hand, if the place is situated at an elevation,the station level pressure will be different from the sea level pressure.The sea level pressure of the above place can be calculated using the station level pressure and it can be seen that the sea level pressure calculated as above is more than the station level pressure.
The atmospheric pressure over different places will be different(depending upon the elevation of the place) and the corresponding sea level pressure are always calculated for comparison purposes so that low and high pressure areas can be identified.

Answer 3

I hope someone with some knowledge about this responds, but I think it is at sea level where the pressure is first measured and then all else is determined from that level...I think. Sorry. But, it is a very interesting question...thank you.

Answer 4

sea level pressure can mean a 'standard' pressure without regard to the actual pressure or it can mean the actual pressure at sea level.

atmosphere pressure is the actual pressure at a specific location ( which can be sea level ).

Answer 5

Yes one atmosphere is at sea level.

Answer 6

In physics/chemistry there is a standard temperature and pressure (known as STP) that is used. See the below link and any HS Physics book.

Answer 7

what's the factors? via that, I advise is there a extreme or low stress area over the region? that's going to be fairly greater throughout sparkling, heat climate and fairly decrease throughout a hurricane, and if there's a twister or hurricane interior sight, that's going to be lots decrease nonetheless! So the only thank you to accurately answer the question could be to rather degree the barometric stress at that element.
