==What formula does Cumulus use for Apparent Temperature?==
It uses a formula from the Australian BOM - http://www.bom.gov.au/info/thermal_stress/#atapproximation
==How does Cumulus know the height of the cloud base?==
It doesn't. It uses a calculation which gives the theoretical height above ground level at which Cumulus clouds might form, based on the current temperature and dew point. It assumes that the difference between temperature and dew point decreases by about 4.4 degrees Fahrenheit per 1000 feet increase in altitude. When the two values coincide, the air is saturated (relative humidity = 100%) and Cumulus clouds may form.
