Noun1.pressure level - the force applied to a unit area of surfacepressure level - the force applied to a unit area of surface; measured in pascals (SI unit) or in dynes (cgs unit); "the compressed gas exerts an increased pressure"
physical phenomenon - a natural phenomenon involving the physical properties of matter and energy
blood pressure - the pressure of the circulating blood against the walls of the blood vessels; results from the systole of the left ventricle of the heart; sometimes measured for a quick evaluation of a person's health; "adult blood pressure is considered normal at 120/80 where the first number is the systolic pressure and the second is the diastolic pressure"
gas pressure - the pressure exerted by a gas
head - the pressure exerted by a fluid; "a head of steam"
hydrostatic head - the pressure at a given point in a liquid measured in terms of the vertical height of a column of the liquid needed to produce the same pressure
intraocular pressure, IOP - pressure exerted by the fluids inside the eyeball; regulated by resistance to the outward flow of aqueous humor; "glaucoma can result from increased intraocular pressure"
oil pressure - pressure that keeps oil on the moving parts of an internal-combustion engine
osmotic pressure - (physical chemistry) the pressure exerted by a solution necessary to prevent osmosis into that solution when it is separated from the pure solvent by a semipermeable membrane
corpuscular-radiation pressure, radiation pressure - the minute pressure exerted on a surface normal to the direction of propagation of a wave
instantaneous sound pressure, sound pressure - the difference between the instantaneous pressure at a point in a sound field and the average pressure at that point
suction - a force over an area produced by a pressure difference
vapor pressure, vapour pressure - the pressure exerted by a vapor; often understood to mean saturated vapor pressure (the vapor pressure of a vapor in contact with its liquid form)

Predictors such as mean sea level pressure, humidity, geopotential height, relative humidity, and temperature may be used to downscale precipitation forecasts to the desired region and popularity [2-13].
The daily data from May to October of the past 30 years from 1982 to 2011 were obtained from the National Centers for Environmental Prediction (NECP) Climate Forecast System Reanalysis (CFSR), including horizontal wind field and geopotential height field at 850 hPa and 200 hPa; geopotential height field at 500 hPa; sea level pressure field with a resolution of 0.5[degrees] x 0.5[degrees]; and sensible heat flux, latent heat flux, and precipitation rate in the Gaussian grid.
The presence of high pressure (high geopotential height) or a ridge at this level corresponds with heightened coastal fog conditions.
--Computing the geopotential height differences and geopotential heights of benchmarks,
To investigate mid-tropospheric circulation patterns, 500-hPa geopotential height data for January were obtained for the time period between 1950 and 1996 from Kalnay et al.
The 500 mb geopotential height fields indicate a trough moving through the period with light zonal winds (Figure 7(a)).
Synoptic conditions of snow events were characterized by extracting temperature and geopotential height at 850 and 500 hPa from NCEPNCAR reanalysis data [26] of the 241 events in the database, over the region 30-60[degrees]N by 30[degrees]W-10[degrees]E with 2.5[degrees] resolution.
