Look again at the contour map and focus your attention on the southern-most peak, Mauna Loa. What range of pressures would you consider possible at point "P"? Isobars that are spread apart indicate a smaller pressure. Definition of an Isobar This tool is called an isobar. Isopleths of temperature are called isotherms (contours of constant temperature), and isopleths of pressure are called isobars (contours of constant pressure). 1000 An isobar is a line on a map that shows a meteorologist what the pressure is at the surface of the earth. If you think of these isobars as elevation (just as a visual aid), you will note that point "P" sits atop a large, flat plateau of pressure. Isotherms are commonly used in meteorology to show the distribution of temperature at the Earths surface or on a chart indicating constant level or constant pressure. Points of equal wind speed isotherms An isotherm is a line connecting locations with equal temperature Isotherm maps show where temperatures are relatively high and low and also . system changes by 8.0J/K-8.0\mathrm{~J}/\mathrm{K}8.0J/K. 4) The internal energy of an ideal gas remains constant when going on an isotherm. how do meteoroligists use isotherms and isobars .
