We know that point "P" is not equal to either of these values because it does not lie on one of the contour lines. The isobaric pattern on a constant-height surface is extremely useful in weather forecasting because of the close association between pressure and weather. The series of reactions is, (a) Assuming that the protonproton cycle requires a temperature of 1.51071.5 \times 10^71.5107 K, estimate by proportion the temperature required for the carbon cycle. Here in Missouri, we have another one of those cases where it looks like its between contours with the same value. . Isobars that are close together indicate a large pressure. An isotherm is a line on a map or chart of the earth's surface connecting points having the same temperature at a given time or the same mean temperature for a given period. It is cold in January because the Earth is furthest away from the sun. Isotherms and isobars allow us to view large scale processes much more easily than looking at the raw data from individual weather stations itself. Click to see full answer. You should also be able to estimate a value at a point on a contour map of temperature or pressure (or any variable, for that matter). Some portions adapted from original course materials by David Babb and Lee M. Grenci. Meteorologists use isobars on weather maps to depict atmospheric pressure changes over an area and to make predictions concerning wind flow.
