Step #3 - draw in a tentative location for the cold front. Locating and drawing in the cold front. Step #4 - double check the front location. We should double check the front location using some of the other weather changes (wind shift, dew point, pressure change etc.) that precede and follow a cold front. Here’s an example: In the case of air with a dew point temperature Td = 10°C (50°F) and pressure p = 1 bar (14.5 psi), the water vapor partial pressure is 12.33 mbar (1233 Pa). If this air is now compressed sevenfold to 7 bar (101.5 psi), then the water vapor partial pressure (see Dalton's Law) also increases sevenfold to 86.31 mbar (8631 Pa). It suggests that the air at a dew-point temperature cannot hold any additional water. When the air reaches the dew-point temperature at a particular pressure, the water vapour is in equilibrium with liquid water, meaning water vapour is condensing at the same rate at which liquid water is evaporating. The hygrometer is used to calculate the Dew ... Sampling Location. The place where you extract your air sample from can impact your dew point readings. Samples should typically be taken after the refrigerant dryer, as this will reflect the moisture content of the air at its driest point.
