Environmental Science
Low clouds retard surface cooling at night better than clear skies because:

The clouds start convection currents between them
The clouds absorb and radiate infrared energy back to earth
The clouds are better conductors of heat than is the clear night air
The formation of the clouds releases latent heat energy
The water droplets in the clouds reflect infrared energy back to earth
