Isobar: On a weather map, a line drawn through all points of equal air pressure. Isobars form closed loops, and cannot branch or end. Isobaric patterns identify areas of relative high and low air ...

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 ...

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 on weather maps are lines connecting locations with the same air pressure. Isobaric lines form closed loops, thereby identifying areas of low or high air pressure. For example, if all ...

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 ...

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 ...

The Mean Sea Level Pressure Analysis is one of the most familiar images in the community. It is compiled from hundreds of weather observations (synoptic data) taken simultaneously around the ...

Air has weight, even though we rarely feel it. A column of atmosphere stretching from sea level to the edge of space presses ...

And while the weather presenter pointing at all the bright lines and markers on the synoptic chart certainly know what they’re talking about, the average Joe or Joanne doesn’t. In fact most of us have ...

Isobars are originally lines used in meteorology. On Chunmi Kim's canvas, however, these lines drift slightly away from being mere symbols for measuring atmospheric pressure. They remain as traces of ...
