Isobar

An isobar is a line of equal or constant pressure on a graph, plot, or map; an isopleth of pressure. In meteorology, the pressures shown are reduced to sea level, not the surface pressures at the map locations.

Pressure: Pressure is the amount of force applied normal to a surface divided by the area of that surface. As an example of varying pressures, a finger can be pressed against a wall without making any lasting impression; however, the same finger pushing a thumbtack can easily damage the wall. Although the f...
