Moisture and Advection

back
The advection of new air masses into a region affects temperature and moisture content. Roll over the time line below to compare how three different air masses might affect temperature and vapor pressure in Kansas City. Each case is plotted against the changes you might expect on a windless (no advection) day. You can view these changes using a saturation pressure curve or a hygrothermograph.
