摘要：
The sensitivity of the results of calculating atmospheric flow helicity in the atmospheric boundary layer with respect to the factor of nonstationarity and details of the eddy exchange description is theoretically investigated. The study shows that estimates often used in the framework of the classical Ekman model can lead to significantly overestimated values of helicity. Appropriate estimates and variants of refined calculations are given.
