An air mass that forms over water at high latitude is most likely cold. The air mass over the water would also be quite humid.
Marititime Air Masses
An air mass that forms over water at a high latitude is most likely cold and humid. It would be cold because the higher the latitude the colder the air.

A desert is dry. It does not produce a lot of water vapor. An air mass that forms over a desert will have low humidity.The desert receives an extremely low amount of precipitation (rain, snow, etc. that has fallen at a place in a given period) or lack of water. This would make an air mass that forms over a desert have low humidity (The air mass would not be moist).
A hot air mass that forms over land is called a continental air mass.
polar air mass (meteorology), air mass that forms over land or water in the higher latitudes.
polar air mass (meteorology), air mass that forms over land or water in the higher latitudes.
Maritime Air Mass
Continental air masses form over land. These air masses are typically dry, as they have little moisture content due to the lack of proximity to water bodies. They are characterized by their stable and homogeneous characteristics.
