Thermal stability also describes, as defined by Schmidt (1928), the stability of a water body and its resistance to mixing. This is the amount of work needed to transform the water. (e.g. a lake) to a uniform water density. The Schmidt stability 'S' is commonly measured in Joule per square meter or g*cm/cm. Compare Stratification. "thermal stability can also be defined as the no change at micro-structural level."
