The scale for humidity has a minimum value of 40%. However, if you could change the humidity to zero and set a 70°F difference between temperatures, would precipitation occur? Why or why not? What type of weather would you expect?
Relative humidity (RH) is the ratio of the partial pressure of water vapor to the equilibrium vapor pressure of water at a given temperature. Relative humidity depends on temperature and the pressure of the system of interest. It requires less water vapor to attain high relative humidity at low temperatures; more water vapor is required to attain high relative humidity in warm or hot air.
