In this case, we can see that point "P" is about half-way between the two contours and thus has an elevation of approximately 3,500 feet. Widely spaced isotherms (line A-B in Figure 5.12) indicate a small change in temperature over distance and closely . On a weather map, isobars are contour lines that connect different locations or points with the same constant pressure, while isotherms are also contour lines, which specify locations that are at the same constant temperature. Meteorologists use isobars on weather maps to depict atmospheric pressure changes over an area and to make predictions concerning wind flow. They show how temperature and pressure are changing over space and so help describe the largescale weather patterns across a region in the map., What role does the Automated Surface Observing Systems (ASOS) play in weather forecasting? On our map, point "P" lies between 3000 feet and 4000 feet contours, so the elevation at point "P" is greater than (but not equal to) 3000 feet but less than (but again, not equal to) 4000 feet. Similarly, meteorologists contour maps of temperature because such maps allow them to easily spot areas of cold and warm air. isotherm, line drawn on a map or chart joining points with the same temperature. They are lines that connect equal points of pressure. The feature that would immediately jump out at a weather forecaster as a region of "active" weather is the large area of low pressure centered over the Midwest (near the Iowa / Wisconsin border). Keeping this in consideration, how do meteorologists use isotherms and isobars? a. For example, a temperature of 30 and a dew point of 30 will give you a relative humidity of 100%, but a temperature of 80 and a dew point of 60 produces a relative humidity of 50%.
