Question

5 Point on Horizontal Distribution of are Pressure​

Answer 1

The distribution of atmospheric pressure over the globe is known as horizontal distribution of pressure.
It is shown on maps with the help of isobars. An isobar is a line connecting points that have equal values of pressure.
Isobars are analogous to the contour lines on a relief map.
The spacing of isobars expresses the rate and direction of change in air pressure.
This charge in air pressure is referred to pressure gradient.
Pressure gradient is the ratio between pressure difference and the actual horizontal distance between two points.
Close spacing of isobars expresses steep pressure gradient while wide spacing indicates gentle pressure gradient.
The horizontal distribution of atmospheric pressure is not uniform in the world.
It varies from time to time at a given place; it varies from place to place over short distances.
