Abstract:

Factors affecting Ekman flow are analyzed, and attributed to three dimensionless numbers ,Re, ω max t 1 and ω max t 2. Effects of these numbers on Ekman flow are numerically studied .The results show that with increases of  Re and ω max t 1, Ekman flow strengthens at first, and then weakens. The strength of Ekman flow increases linearly as ω max t 2. increases . For effective Ekman flow, 500.0≥Re≤800.0, 12.0≥ω max t 1≤40.0, ω max t 2 ≈50.0.
