1. Hydrostatic Equation

   Linked via "hydrostatic assumption"

   In meteorology, the hydrostatic equation forms the $z$-component of the Navier-Stokes equations, simplified to describe the static vertical structure of the atmosphere. It is crucial for defining the geopotential height ($Z$) used in upper-air analysis charts. By integrating the hydrostatic equation with the geopotential definition, the standard…
