Time evolution of the midplane thermal and turbulent pressures (a) and the thermal and turbulent velocity dispersions (b)
of the diffuse component for model QA10x2. In (a),
P
th initially decreases as the gas cools, while
P
turb increases rapidly after the gas falls toward midplane and is stirred up by SN explosions. After a few cloud formation and
feedback cycles (a few 10 s of Myr),
P
th and
P
turb reach saturation values of
P

−3 K and
P
turb/
k
B

−3 K, respectively, with a relative fluctuation amplitudes of 0.21 and 0.52. In (b), the velocity dispersions saturate at
v

−1 and
v

= 6.8 km s
−1, respectively, with relative fluctuation amplitudes of 5% and 30%.
