A bar is a metric unit of pressure and isobars are lines on a weather map that connect points of equal pressure. Since variations in air pressure drive the atmosphere’s winds, isobars also give ...

Whenever strong, damaging winds occur, there is always concern about the risk of fallen trees and damage to power lines. In fact, severe weather is responsible for nearly 80 percent of all major power ...

Hourly weather observations that include sea-level pressure readings are plotted or printed on weather maps that meteorologists can analyze. Isobars are drawn by connecting points having equal ...

CONFUSED by a trough? Don’t know the difference between a low and high? Here’s how to make sense of the weather. And while the weather presenter pointing at all the bright lines and markers on the ...

Hourly weather observations that include a sea-level pressure reading are plotted or printed on weather maps that meteorologists or computers can analyze. The isobars are drawn by connecting lines of ...

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 ...

Isobars are lines on a weather map joining together places of equal atmospheric pressure. On the map the isobar marked 1004 represents an area of high pressure, while the isobar marked 976 represents ...
