A proxy named "upwelling age", defined as the ratio of wind time scale to "advection time", was developed to quantify the local tendency for coastal upwelling. The formulation of the "advection time" was derived from Ekman theory. A 3D numerical model was used to validate and refine the theoretical formula by simulating a total of 30 cases of different bottom topographies and wind stresses. The results agree reasonably well with the theoretical formulation although some modifications are necessary. The final formulation of the "advection time" was parameterized as a function of pycnocline depth, bottom slope, and wind stress.
