Cool air is typically dry because cold air has a lower capacity to hold moisture compared to warm air. As cool air cools down, its ability to retain humidity decreases, leading to lower relative humidity levels. This is why cold environments often feel dry.
high pressure
Maritime tropical: Warm and moist air masses originating over tropical oceans. Maritime polar: Cool and moist air masses originating over cold ocean waters. Continental tropical: Warm and dry air masses originating over hot and dry land areas. Continental polar: Cold and dry air masses originating over cold land areas.
Dry parcels cool faster than moist parcels because water has a high heat capacity, meaning it takes more energy to heat up or cool down compared to dry air. Therefore, dry air loses heat more quickly than moist air because it has less moisture to retain heat.
cool and dry
Dry air tends to cool faster than wet air because water vapor in the air absorbs heat energy, making it harder for the air to cool down. On the other hand, dry air does not have this heat-absorbing property, so it cools more quickly when exposed to lower temperatures.
A high pressure center is characterized by cool dry air, as it is associated with descending air that warms and dries as it sinks towards the surface.
When cool dry air meets warm moist air the result is thunderstorms. If other conditions are present those storms scan produce tornadoes.

It dries faster with hot air.

where the temperature is cool, and there is not much water vapour in the air (low humidity) or not much rain
Swamp coolers depend on evaporation of water to cool the air. The hotter the temperature and drier the air, the better they are able to cool.
