Lines of equal (iso) air pressure (barometric).
Similar concepts are isohypnals (equal contours of rainfall); and isopachs, lines of equal thickness of a deposit; and isotherms which concern temperature.

How do isobars measure air pressure?
Isobars are not measured. An isobar describes a part of a thermodynamic process during which the pressure doesn't change. It is also used as a term in graph tables where it describes the behavior of a material at a constant pressure.
Why do jet streams flow parallel to isobars?
Because jet streams are above the friction layer, they have a negligible effect. The wind is balanced by the Coriolis effect and the pressure gradient so that the winds flow parallel to isobars.
What do isobars indicate when they are far apart?
Light windsWidely-spaced isobars indicate low wind speeds.
How do you determine where the strongest winds are on a weather map?
The barbs are arrows pointing in the direction wind blows from. They have little points (barbs) off the side of them. A full barb represents 10 knots, a half barb represents 5 knots, and a flag represents 50 knots. You add the numbers represented by the number of full and half barbs. Thus 2 full barbs and 1 half barb represents a 25 knot wind. To convert knots to MPH multiply the knots by a factor of 1.15.
What are three types of isolines?
Isobars - Measure atmospheric pressure Isotherms - Measure temperature Isoheights - Measure elevation
Which would show stronger winds widely spaced isobars or closely spaced isobars?
Closely spaced isobars mean stronger winds, as it indicates a tight pressure gradient.
What does it mean when isobars are spaced out?
It means the wind will be weak.
How can you use isobars to show us the direction of the wind?
The isobars are generated from mean sea level pressure reports and the pressure values are given in millibars.
What is the difference between isobar and isotope?
isobars are elements with same mass numbers (Atomic Mass) and different atomic number (number of proton or electron)
What is the similarities between isobars and isotherms?
what is the similaraties between isobars and isotherms ]
Where would you generally see isobars?
Yea, where would you generally see isobars??
What is the purpose of isobars?
Isobars show different pressure areas on a weather map.
How are isobars and isotherms alike?
Isobars are lines of equal pressure, isotherms are lines of equal temperature. And isobars are pretty and gorgeous, and isotherms are thermometers.
WHAT DO Isobars represent?
Isobars on a map represent areas on the map of similar atmospheric pressure.
Examples of isobars in chemistry?
Isobars 7N14, 6C14 2He3, 1H3 92U239, 93Np239
What are Isobars and what does it mean when they are close together?
It means that there is a steep gradient, or pressure change, and strong winds.
What measures isobars?
Isobars measure the air pressure in the sky and our atmosphere! I hope I helped a little!
