In numerical weather prediction,what is the hydrostatic equation used to describe?
A)changes in atmospheric density
B)vertical motion in the atmosphere
C)the impacts of changing temperature
D)horizontal advection

Question

Quizplus · Accepted Answer

The hydrostatic equation is used to describe vertical motion in the atmosphere, specifically the balance between the upward pressure gradient force and the downward gravitational force. It relates changes in pressure to changes in height and is a fundamental equation in atmospheric thermodynamics and dynamics. It does not directly describe changes in density, temperature, or horizontal advection.
