Tottenham Hotspur reveal more about what the club's new north London stadium will look like.
Although the actual atmospheric lapse rate varies, under normal atmospheric conditions the average atmospheric lapse rate results in a temperature decrease of 6.4 Â°C/km (3.5 Â°F or 1.95 Â°C/1,000 ft) of altitude above ground level. The measurable lapse rate is affected by the moisture content of the air (humidity).he decrease of an atmospheric variable with height, the variable being temperature unless otherwise specified. In the lower regions of the atmosphere (up to altitudes of approximately 12,000 metres (39,000 ft), temperature decreases with altitude at a fairly uniform rate.
The chemical composition of the troposphere is essentially uniform, with the notable exception of water vapor. The source of water vapour is at the surface through the processes of evaporation and transpiration.urthermore, the temperature of the troposphere decreases with height, and saturation vapor pressure decreases strongly as temperature drops, so the amount of water vapor that can exist in the atmosphere decreases strongly with height.
