This massive upward movement of supercooled cloud liquid water increases the amount of cloud ice.
Much like its cousin freezing rain and freezing drizzle, freezing fog is a layer of supercooled cloud droplets.

They chose 62 miles because that is the distance it takes an aircraft to reach 10,000 feet, where many of the supercooled cloud layers are located.

Supercooled warm rain process refers to that when there is no warm layer greater than 0[degrees]C, the size of supercooled cloud droplets (diameter larger than 40 [micro]m) increases by collision-coalescence, which is the main mechanism for the formation of freezing drizzle.
In the dry season, a larger fraction of the precipitation will be produced in the mixed-phase region, by riming of supercooled cloud droplets onto ice particles and by migration of water vapor to liquid water and ice particles.
Aircraft measurements in CalWater-1 showed that clouds in pristine air masses with dearth of ice nuclei were devoid of ice and snow and had persistent supercooled cloud and rainwater down to -21[degrees]C (Rosenfeld et al.
By seeding ice in a supercooled cloud by adiabatic expansion, Yamashita (1973) showed that in crystals grown at around -15[degrees]C no trigonal or scalene hexagons formed out of 50 observed crystals; whereas at -7[degrees]C, 69% of the 109 observed crystals had threefold symmetry [seeding using dry ice resulted in a similar trend (Yamashita 1973)].
In the introduction, we gave examples of the shortcomings of current models in representing vertical profiles of aerosol, boundary layer cloud occurrence, mean ice water path, regional radiation biases, and the radiative impact of subvisual cirrus and midlevel thin supercooled cloud layers.
While direct refrigeration is not provided, the rapid expansion of the air from the chamber permits an adiabatic lowering of the cloud temperature by as much as 50C[degrees], and this has allowed us to produce controlled warm clouds, supercooled clouds or ice crystal clouds in accordance with the special requirements of any given experiment.
