The phrase
"environmental lapse" refers to the decrease in temperature that happens with an increase in altitude or height. As you go higher up in the atmosphere, the temperature starts decreasing, and this is what the term
environmental lapse signifies.
Full definition
This implies that there was full convection from the surface to about 15,000 feet above sea level in the region, and
environmental lapse rates were near or at the dry adiabatic lapse rate.
In the troposphere, temperatures decrease with height at
the environmental lapse rate we mentioned above, i.e., -6.5 °C per kilometre -LRB--3.5 °F per 1,000 feet).
The steeper
the environmental lapse rate, the more potentially unstable is the atmosphere.
