Answer: (C) The amount of instability present within a column of air.
Step-by-step explanation:
The logarithm function is basically used in the meteorology that describe the amount of the instability that are present in the column of the air.
It is basically used in the wind pipe profile for the measurement of the total estimator of the mean of wind speed.
The measurement of this total wind pipe estimation is basically measure above the height of the ground. Therefore, this logarithm function is basically measure in present of the column of air.
