Two common types of fronts include the cold front and the warm front. The cold front (see " \( A \) " in the figure above) generally has a much steeper slope than the warm front (see " B " in the figure). Air masses of different temperature-humidity characteristics do not readily mix -- so the less dense of the two (the warmer air) is forced aloft. Most frontal cyclones contain a cold, polar air mass from high latitudes in conflict with a warmer tropical or subtropical air mass from the lower latitudes. Frontal cyclonic activity is most common during the cooler months in the mid-latitudes when polar air invasions are most frequent. As a rule, tropical locations seldom experience strong frontal cyclones.

The air temperature at the surface is 52 degrees F and the relative humidity is \( 66 \% \). What is the saturation capacity of the air in grams per kilogram \( (\mathrm{g} / \mathrm{kg}) \) ? 6.336 7.966 5.258
