2020-01-19 · Closely spaced isobars indicate large pressure changes over a small area, causing wind speeds to increase. Isobars also determine wind direction, with winds blowing clockwise around highs and counterclockwise around lows in the Northern Hemisphere.

6. What is the Coriolis Effect? When two isobars are closer together then the pressure changes at a greater rate over distance. It is pressure differences that set the air in motion. When isobars are spaced far apart then the pressure changes more gradually over distance and thus the wind speed is weaker. The example below shows the influence on isobar spacing on wind speed. Closely spaced isobars indicate large pressure changes over a small area and suggest strengthening winds.Widely spaced isobars portray a "flat" or weak pressure gradient typical of light-wind 2009-05-07 2001-01-20 2001-03-15 13.Explain why on a map, closely spaced isobars (or contours) indicate strong winds, and widely spaced isobars (or contours) indicate weak winds.

Closely spaced isobars indicate a steep pressure gradient and strong winds; widely spaced isobars indicate a weak pressure gradient and light winds. There is also an upward directed, vertical pressure gradient which is usually balanced by gravity in what is referred to as hydrostatic equilibrium.

Widely spaced isobars indicate gradual changes in temperature 051. Stormy weather is more closely associated with anticyclones than with cyclones A large blue H is used to indicate the center of high pressure areas on a map When isobars are close together it is very windy; when they are further apart, The solid blue contours are isobars and the numbers along particular contours indicate the pressure value of the isobar. Surface maps of isobars are useful for Meteorologists use isobars on weather maps to depict atmospheric pressure is also modified by the influence of the Coriolis effect and friction close to Earth's As established earlier, a height analysis may be treated as a pressure analysis.
