The hydrostatic equation is one of the most important and most basic equations in meteorology. Understanding the equation makes it easier to physically interpret analysis and thickness charts. The equation is: dP/dz = - density*gravity;

The hydrostatic equation states that whenever there is no vertical motion, the difference in presuure (dp) between two levels (dZ) is caused by the weight of the layer of the air ( mass * acceleration due to gravity = ). Note that acceleration due to gravity (g) is a constant if Z is the geopotential height (if...

Hereafter, hydrostatic eqilibrium will be understood to imply hydrostatic equilibrium of a fluid in the presence of a field of gravity of the earth (i.e., ... which is the scalar form of the differential equation for hydrostatic equilibrium. ... This is the complete statement of the hydrostatic equation in vector form.

Preliminaries: the hydrostatic equation Before delving into the details, let's re-consider the constant-density fluid more mathematically. We need to use a little elementary calculus for this. We'll use the conventional symbol [Greek lowercase rho: ρ] for density.

In the system the hydrostatic equation is approximated in a general way by ... The matrix , referred to as the hydrostatic matrix, represents the discrete approximation to the hydrostatic integral and is left unspecified for now. It depends on pressure, which varies from horizontal point to point.

The experimental set up is made of low cost, easy obtainable materials: two perspex tanks of different dimensions, several loads, transparent tube and a differential U manometer. The smaller tank (10 cm side, by 50 cm high) has ... The interest of this experimental activity is to raise on the student some unexpected questions,

The horizontal pressure gradient is 1/r * dp/dx, which is (dp/r)/dx which, as you can see from of the hydrostatic equation above is just the change in dynamic height from one station to the other divided by the distance between stations -- remember H == g*dz == dp/r. Thus the horizontal pressure gradient force = H /
