These isobars thus retain the memory of the initial destabilization and their disturbance is what maintains the growth in sectors in the long term.
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.
Usually, they beta-decay to their nearby even-even isobars that have paired protons and paired neutrons.
