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 ...

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 ...

MIKE MOSS SAYS: Randy, There isn't a single, enformced standard for what we would call the "contour interval" for pressure analyses. However, there are three such spacings that are by far the most ...

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 ...

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 ...

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 ...

On the map the isobar marked 1004 represents an area of high pressure, while the isobar marked 976 represents an area of low pressure. Not only do isobars tell us whether there is high or low pressure ...

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 ...
