Definition of the Day
Overlandflow
The unconcetrated movement of water along slopes as sheetwash or concetrated in rills

Lapse Rates

Temperature changes occuring without the addition or subtraction of heat are called Adiabatic temperature changes

General tip
This is different from latent heat which changes state of a substance without altering temperature.

Environmental Lapse Rate

The decrease in temperature of the whole atmosphere as we ascend high.The average rate of decrease is 6.5oC/1000m.In other words every 1000m increase in height temperature drops by 6.5oC.
Environmental Lapse Rate

Dry Adiabatic Lapse Rate

The decrease in temperature of air parcels with height.The rate of decrease is 9.8o/1000m.
dry Adiabatic Lapse Rate
The air is dry upon the fact that it has not reached saturation or has not condensed.

Saturated(wet) Adiabatic Lapse Rate

When an air parcel condense it continue rising beyond the condensation level, but this time the rate of cooling drops to 5o C/1000m due to latent heat released during condensation.
Saturated Adiabatic Lapse Rate
