Question

Consider the same air mass from question 16: the velocity of uplift is measured at 240 meters per
hour. At what time can we expect cloud formation? Be precise in your answer.

Answer 1

the rate of change of the saturation ratio S is given by:

$\frac{ dS}{dt}=P-S=Q_1×\frac{ dz}{dt} - Q_2×\frac{ dλ}{dt}$

where P= production, C= condensation

$\frac{ dz}{dt}$ is the vertical air velocity

$\frac{ dλ}{dt}$ is the condensation rate

Time is equal to 2.5 hour
