The difference between vorticity equation and potential equation
Vorticity equation is an equation obtained by divergence operation of vector motion equation. It gives the time change rate of relative vorticity of gas block, and its vertical component equation is commonly used in meteorology.
The potential equation is: in weather forecast, when analyzing the development of weather situation, it is necessary to analyze the change of atmospheric vorticity. Although the vorticity equation is simple, the horizontal divergence represented by the horizontal divergence term at its right end cannot be directly judged from the weather map, and even it is difficult to accurately judge with the measured wind. Therefore, through some transformations, it can be transformed into a potential equation that is easy to judge the development of the situation.
