A line connecting or marking places upon the surface of the earth where height of the barometer reduced to sea level is the same either at a given time, or for a certain period (mean height), as for a year; an isopiestic line.
Lines on a map connecting points of equal atmospheric pressure at a particular time.
The lines on a plot (map) showing continuous level. In a speaker plot, it shows the pattern where the sound is a given level lower than the direct center (on-axis) at a given frequency. For microphones, the isobars on the plot show the relative sensitivity at different angles off axis (based on frequency). Usually isobars are given in increments of 3 or 10dB.
A line on a map along which the air has a specified pressure.
Compare with isotope. A contour line that corresponds to values measured at identical pressures. For example, curves on a plot of gas volumes measured at different temperatures in an open container are isobars. Nuclides that have the same isotopic mass but different atomic number.
a line on a synoptic chart joining points of equal atmospheric pressure.
a line on a map joining places of equal air pressure
Is a process taking place under constant pressure. To change the volume from state 1 to state 2, heat must be removed. The temperature change is proportional to the change in specific volume. ( 060)
Lines on a map joining points of equal atmospheric pressure.
An isopleth of pressure.
Line on a weather map joining points of equal pressure.
an isogram connecting points having equal barometric pressure at a given time
a curve along which pressure is constant and is usually drawn on a constant height surface such as mean sea level
a line connecting locations of equal atmospheric pressure
a line connecting locations of equal barometric pressure
A line on a weather map linking areas with equal air pressure
A line on a weather chart showing places having the same atmospheric pressure at the same time.
A line on a weather map that connects points of equal pressure. On a weather map, isobars extend around areas of high and low pressure.
A line connecting points of equal atmospheric pressure on a weather map.
Line joining points of equal barometric pressure reduced to sea-level datum.
The lines drawn on a weather map that connect points of equal air pressure.
Lines of equal barometric pressure as shown on a weather map.
Isobar is a line connecting points of equal pressure on a graphical representation of a physical system.
A line on a weather map drawn through points of equal pressure reduced to mean sea level. Isobars show the pressure distribution at any given time.
A line on a weather map that surrounds an area with the same atmospheric pressure.
A line connecting points of equal atmospheric pressure. De Blij, H. J., and Perter O. Muller; Geography - Regions and Concepts; John Wiley and Sons, Inc.; New York, Chichester, Brisbane, Toronto and Singapore; 1992; page 606.
A line of equal or constant pressure.
A line of equal barometric pressure on a weather map.
A line on a weather map connecting points of equal air pressure.
On a weather map, a line connecting points of equal pressure.
is a type of isoline which is used on a weather map to connect areas of equal atmospheric pressure
the line of equal pressure denoted on surface weather maps.
a line of constant pressure that connects points on a weather map that have the same pressure.
An isobar is a line on a weather map that represents constant barometric (air) pressure.
A line through points of equal atmospheric pressure.
The line drawn on a weather map connecting points of equal barometric pressure.
