Thermocline

Real World Example

Imagine you're in an elevator that suddenly has a drastic change in temperature as it moves between floors. Just like how you experience a sudden shift in temperature, a thermocline in a fluid, such as a lake or ocean, is a layer where the temperature changes rapidly with depth. In this analogy, the elevator acts like the depth of the water, and the sudden temperature change you feel between floors mirrors how temperature shifts quickly in the thermocline layer of the fluid.
