Meanwhile, regions of low pressure are often somewhat unsettled (cloudy with precipitation). The dew point is the temperature the air needs to be cooled to (at constant pressure) in order to achieve a relative humidity (RH) of 100%. Isotherm. The L stands for low pressure (where we would expect to find the lowest pressure) and H stands for high pressure (where we would expect to find the highest pressure). Each type of isoline is named to reflect the variable being mapped: isotherms are lines of constant temperature; isobars are lines of constant baro-meb-ic pressure; and isodrosothcrms are lines of constant dew point. c. Atmospheric conditions You can specify conditions of storing and accessing cookies in your browser. 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. It looks like it lies between two 85 degree isotherms.
