MIKE MOSS SAYS: Phil, Winds would be perpendicular to the isobars is not for the rotation of the earth, which imposes a virtual force called the Coriolis effect. Over a significant time and distance ...

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 ...

An isobar is a line of constant pressure. These lines are often measured in 2, 4, or 10 millibar increments. When you see lots of isobars over an area, most likely that area is experiencing lots of ...
