An isobar is a line of equal pressure on a map . In meteorology, the barometric pressures shown are reduced to sea level, not the surface pressures .

The National Weather Service makes weather maps with special lines. Isotherm is a line that connects points of equal temperature. Isobar is a line that is drawn to connect equal atmosphere pressure.
Meteorology. a line drawn on a weather map or chart that connects points at which the barometric pressure is the same.(D)to connect points of equal air pressure on a weather map
A line on a weather map connecting points of equal atmospheric pressure.
H means high pressure, or cold and dry with little chance of stormy weather. L means low pressure, or warm and moist with a probability of storms. A line with triangles means it will bring cold, stormy weather. A line with half circles, gentle steady rain or snow that lasts for a long period of time. Those are the most simple weather symbols.
Those lines are isobars. They indicate the line at which air is at that certain air pressure.
Line of constant pressure shown on the surface pressure diagram are called isobars. Isobars show areas of high pressure and areas of low pressure. The surface pressure diagram can be used to predict weather patterns.
The lines connecting points of equal temperature on a weather map are called isotherm lines.The two parts of the word isotherm are isomeaning "same" and therm meaning "temperature".A similar construction is used for isobar, meaning a line of equal pressure.
There are several different lines on a weather map. Lines with triangles leading out from them are referred to as cold fronts, while lines with semi-circles leading out from them are warm fronts. There are also lines on a weather map that are called isobars. They connect areas of equal barometric pressure.
