A bar is a metric unit of pressure and isobars are lines on a weather map that connect points of equal air pressure. Because variations in air pressure drive atmospheric winds, isobars give ...
Isobars are lines/areas of equal pressure represented on a weather map. When isobars become very tightly grouped together it indicates a "tight pressure gradient" (steep slope). The tightly packed ...
Paris Alston: This is GBH’s Morning Edition. When trying to make sense of the weather and meteorological patterns, there are a lot of helpful tools out there. One of them is isobars, the curved lines ...
