The geostrophic balance is also seen in weather maps, which show upper-level winds blowing along isobars. By mid-day the wind had become south-westerly again with weak ridging evident in the isobars. For this reason they are the disturbances which disturb the furthest isobars. For example, as heat is applied to a body of water the resulting temperature increase follows an isobar below the saturation point of water. Just as a weather map might have isobars joining points of equal air pressure, a noise map can have contours (isophons) joining points having the same noise level. This process produces stable isotopes by moving along the valley of beta-decay stable isobars in the chart of isotopes.

Like isobars, they follow diagonal lines, but at right angles to the isobar lines; from upper-left to lower right.

This process occurs when a nucleus has an excess of neutrons with respect to protons, as compared to the stable isobar.

The isobars of the ordinary weather charts summarise these pressure measurements, adjusted to the mean sea level for uniformity of presentation, at one particular time.

Thus, the actual wind would equal the geostrophic wind only if there were no friction and the isobars were perfectly straight.
