At all points, the pressure gradient points to the direction of maximum increase of "p" and is always normal to the isobar at that point.
Thus, the actual wind would equal the geostrophic wind only if there were no friction and the isobars were perfectly straight.
The lines of equal air pressure are called "isobars".
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.
It gives the melting curve and saturated liquid and vapor values together with isobars and isenthalps.
This process occurs when a nucleus has an excess of neutrons with respect to protons, as compared to the stable isobar.
Like isobars, they follow diagonal lines, but at right angles to the isobar lines; from upper-left to lower right.
Usually, they beta-decay to their nearby even-even isobars that have paired protons and paired neutrons.
