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. Closely spaced contours indicate strong winds just like closely spaced isobars.

How does the Coriolis effect influence air movement? The Coriolis deflects moving air to the right of its path of motion in the Northern Hemisphere and to the left of its path of motion in the southern Hemisphere What do closely spaced isobars indicate? that there is a steep pressure gradient and high winds. What do widely spaced isobars indicate? Closely spaced isobars indicate large pressure changes over a small area and suggest strengthening winds.

– Closely spaced isobars indicate a stronger pressure gradient and increased wind speeds – Horizontal pressure gradients are small relative to vertical ones. 5 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.

Air flows from areas of high pressure to areas of low pressure. The more tightly packed the isobars the faster the air moves across them. Answer: The answer is: letter d, Isobars that are closely spaced indicate a large pressure difference over a small area and strong winds.Isobars that are far apart indicate a small pressure difference over an area and light winds.
