What are the characteristics of Isobar?

1.	What are the characteristics of Isobar?
Answer» The distribution of pressure over the earth’s surface or part of it is shown by means of isobars. The term isobar means line of joining the places of equal pressure. Important characteristics of isobars are: If the isobars are far apart, it indicates gentle pressure gradient as well as calm weather characterized with light surface winds. The isobars usually follows east-west trend. The isobars deviate in their trend at the point of their entrance from sea to land as well as from land to sea. The isobars are almost parallel to latitudes in the southern hemisphere due to predominance of oceans. If the isobars are close to earth other it represents steep isobaric gradient. It also indicates more atmospheric disturbances as well as strong winds.
