Station Pressure is the actual pressure the station records, however this isn't really used in meteorology as there is no comparsion due to elevation, therefore for a synoptic look, Station Pressure is converted to Sea Level Pressure.
It is the difference in pressure created by the Mass of two columns of Air, with the station pressure being the force of the column of Air from above the station and extending to space, and the Sea level pressure being the force of the column of air taken at sea level at the same latitude and extending to space.
Yes, if the station is situated at sea level.
Yes
It will be same as it is at sea level.
The pressure is very low. At the bottom of the mesosphere, the pressure is about one thousandth of sea level air pressure. At the top of the mesosphere the pressure is down to only about one millionth of sea level pressure.
Pressure
Yes, if the station is situated at sea level.
Station Pressure / e* where *=negative elevation/temperature in kelvin x 29.263
Yes
Sea level pressure, sometimes as mean sea level pressure.
Sea level pressure.
the atmospheric pressure below sea level is highter (novanet)
Assuming you are talking about air pressure, atmospheric pressure is created by the weight of the air resting against the earth. the higher up you go, the less air stacked on top of itself, and the pressure is less, until there is no more air at all (space). The pressure of air at sea level is relatively the same around the world because of all the water flows to the same level. this obviously changes with storms and hurricanes - as those move some of the air out of the way. So if you were to go below sea level, there would be more air on top of you, and the pressure would be higher. In death valley (well below sea level) the atmospheric pressure is much higher than at sea level. To answer the question, No, pressure is not negative below sea level. It is greater than at sea level.
Below sea level atmospheric pressure increases with depth. Air pressure at sea level is about 14.7 psia. Air pressure below sea level would be slightly higher.
Air pressure is Greater at sea level.Atmospheric pressure is higher at sea level. There is more atmosphere on top of the observer at that point, so the pressure is higher.
A not-commonly-used measurement is 'atmosphere'. One atmosphere is the average pressure at sea-level: 101.325 kPa, 1013.25 mbar, 29.921 inches of mercury (inHg) or 760 millimeters of mercury (mmHg).
The answer is sea level. Because atmospheric pressure decreases when altitude increases
It is greater.
