temperature gradient. At sea, a temperature gradient is the change of temperature with depth; a positive gradient is a temperature increase with an increase in depth, and a negative gradient is a temperature decrease with an increase in depth. Thesaurus AntonymsRelated WordsSynonymsLegend:

In simple terms, the variation in space of any quantity can be represented (e.g. graphically) by a slope.radient-The space rate of decrease of a function. The gradient of a function in three space dimensions is the vector normal to surfaces of constant value of the function and directed toward decreasing values, with magnitude equal to the rate of decrease of the function in this direction.
