The mixing is also evident from a comparison of the measured temperature with the adiabatic temperature of -33[degrees]C upon reaching 500 hPa; the discrepancy of over 40 K shows that the range of cooling that we can achieve through adiabatic expansion is limited by mixing processes.
During the cell-growth stage, the foam goes through dramatic quenching because of adiabatic expansion and brisk heat absorption during vaporization of the blowing agent.
Alternatively, the heat of compression can be thermally stored before it enters the cavern and used for adiabatic expansion (see below), extracting heat from the thermal storage system.
