WebThe Saturated Adiabatic Lapse Rate (SALR) is therefore the rate at which saturated air cools with height and is, at low levels and latitudes, 1.5°C per thousand feet. At higher altitudes and latitudes, where there is generally less water content in the air, and therefore less latent heat to release, the SALR is closer to 3°C per thousand feet.

WebJun 15, 2024 · In technical terms, the dew point is the temperature at which the air must be cooled to have a relative humidity of 100%. Anything below that temperature is when the airborne water vapor becomes liquid water, and that’s when you see dew on the ground, hence the name. So what does this have to do with humidity? WebThe decrease of the boiling point with altitude can be calculated. For example, the saturation vapour pressure at 40 °C (104 °F) is 74 mb (0.07 standard atmosphere), and the standard …
