Abstract

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.

关于埃克曼边界层的螺旋度

摘要

从理论上研究了大气边界层大气流螺旋度计算结果对非平稳因素和涡交换描述细节的敏感性。研究表明，经典 Ekman 模型框架中经常使用的估计可能会导致螺旋度值显着高估。给出了适当的估计和精确计算的变体。
