二阶非线性微分方程，管理大气电变量的系统数值求解的强度参数的各种值的涡流扩散率的表达式。结果表明，大气电变量对扩散率的变化很敏感，因此可以用来确定涡动扩散率。数值计算结果使它能够确定的扩散无论是从电场剖面测量或从表面测量场和空间电荷。在开放的海洋数据被用来证明该方法的实用性。由于地面放射性和土壤中放射性气体的排放，在陆地上应用同样的技术极为困难。
The system of second-order nonlinear differential equations that governs atmospheric electric variables is solved numerically for various values of the strength parameter in an expression for the eddy diffusivity. The solutions show that the atmospheric electric variables are sensitive to changes in the diffusivity and therefore can be used to determine the eddy diffusivity. The numerical results make it possible to determine the diffusivity either from electric field profile measurements or from surface measurements of field and space charge. Data taken over the open ocean are used to demonstrate the usefulness of the method. Ground radioactivity and radioactive gas emissions from the soil make it extremely difficult to apply the same technique over land areas.
