3) Critically damped: [math]x(t) = (A + Bt)e^{- \gamma t}[/math] This is the optimally damped case, where the damping coefficient is just large enough to completely quell the oscillations, so the oscillator returns to zero in the least amount of time possible. 4) Overdamped: [math]x(t) = Ae^{- \gamma_{1}t} + Be^{- \gamma_{2}t}[/math]
The dry adiabatic lapse rate (DALR) is the rate of temperature decrease with altitude for a parcel of dry or unsaturated air rising under adiabatic conditions.Unsaturated air has less than 100% relative humidity; i.e. its actual temperature is higher than its dew point.he lapse rate is defined as the rate at which atmospheric temperature decreases with increase in altitude. The terminology arises from the word lapse in the sense of a decrease or decline. While most often applied to Earth's troposphere, the concept can be extended to any gravitationally supported parcel of gas.
