Answer:

Stirring, if you are referring to a laboratory experiment.

Upwelling, if you are referring to large lakes or oceans.

Explanation:

The only way for cold water to rise to the surface of any non-agitated container is stirring by whatever means will provide the result.

Upwelling is the result of winds and earth's rotation, and I suspect that rising tides due to the influence of the moon could have some effect.
