... As an example, consider a region of low atmospheric pressure p, known as a depression. Weather maps usually include isobars which are contours of constant p, and the (real) forces acting on air currents push them in the direction of −∇p (i.e., from high to low pressure). Therefore, we might naı̈vely ...
