| Zusammenfassung |
The residence time measures the time spent by a water parcel or a
pollutant in a given water body and is therefore widely used in
environmental studies. The adjoint method introduced by Delhez et
al. (2004) to compute this
diagnostic is revised here to take into account the effect of the
initialization and of the boundary conditions.
In addition to the equation for the mean residence time, it is
suggested to solve a simple advection-diffusion problem to quantify
the effect of the initialization and clarify the interpretation of
the results.
Using the two same equations but with modified boundary
conditions, the method can also be used to quantify the
accumulated time spent by water/tracer parcels in a control
domain. This diagnostic is called "exposure time".
Analytical and realistic model results are used to illustrate the
concepts. |
