Equation 1 describes adiabatic expansion of air when treated as an ideal gas in the air capacitor.
Thirdly, the cloud's natural expansion causes the temperature to drop further (this is called adiabatic expansion) into the 100 picoKelvin range.
Here, we assume the case [partial derivative]d / [partial derivative]S >0 to have a positive temperature which is cooled down through adiabatic expansion. Using the concept of dimensional analysis, (6) gives
Consequently, dynamic process related to adiabatic expansion and ascending movement mainly brings about temperature decrease in SAH after OVTP removal, but the thermodynamic process related to radiative heating offsets the cooling response.
