  1. Hace 4 días · The cloud base is calculated using the formula: \ [ \text {Cloud Base (ft)} = \left ( \frac {\text {Temperature (°F)} - \text {Dew Point (°F)}} {4.4} \right) \times 1000 \] This formula derives from the lapse rate of temperature and dew point in the atmosphere, assuming a standard atmosphere.
