Characteristic Numbers of Heat Transport (independent of tides)
From BAWiki
Motivation
Computation as well as visualization of the tide independent characteristic numbers of heat transport gives some insight into the
- local (rate of change) of heat content,
- mean (horizontal) heat transport due to advection,
- mean (horizontal) heat transport due to diffusion,
- strength of sources and sinks, as well as
- heat exchange between atmosphere and water body
within the period of data analysis.
From these, conclusions can be drawn on the mean (residual) transport of heat, and i. e. the relative significance of advection versus diffusion. For estuaries, fresh water flow, bathymetry, as well as wind shear are considered to be the main influencing factors. I. e. heat exchange between water and atmosphere may be significantly influenced by the wind.
