摘要：
The relation of the hydrodynamic helicity and alpha-effect predicted by the mean-field dynamo theory is considered using the three-dimensional dynamo model in the rapidly rotating flat layer heated from below. Despite the theoretical limitations associated with the requirement of uniformity and isotropism of random fields, the alpha-effect is actually proportional to helicity in the geostrophic flows under consideration. Interpretation of this nice agreement is proposed.
