 | | A "hectopascal" (hPa), is a unit of measurement used by meteorologists to define pressure levels. |
 | | In this case, the 850 hPa level, defines the "middle" portion of the atmosphere (the lower atmosphere being the surface, roughly 1000 hPa, and the upper atmosphere, being less than 300 hPa). |
 | | In this case, at the 700 hPa level, the CRAS model outputs windspeed, measured in "knots" (kts), geopotenial height, measured in "millibars" (mb), and Omega, a diagonistic variable that defines the vertical velocity in pressure units. |
