<P> Thermoclines can also be observed in lakes . In colder climates , this leads to a phenomenon called stratification . During the summer , warm water , which is less dense , will sit on top of colder , denser , deeper water with a thermocline separating them . The warm layer is called the epilimnion and the cold layer is called the hypolimnion . Because the warm water is exposed to the sun during the day , a stable system exists and very little mixing of warm water and cold water occurs , particularly in calm weather . </P>
