Specific humidity (or moisture content) is the ratio of the mass of water vapor to the total mass of the air parcel. [15] Specific humidity is approximately equal to the mixing ratio, which is defined as the ratio of the mass of water vapor in an air parcel to the mass of dry air for the same parcel.
A humid subtropical climate is a subtropical-temperate climate type, characterized by long and hot summers, and cool to mild winters. These climates normally lie on the southeast side of all continents (except Antarctica), generally between latitudes 25° and 40° and are located poleward from adjacent tropical climates, and equatorward from either humid continental (in North America and Asia ...
The snowy city of Sapporo, Japan, has a humid continental climate (Köppen Dfa).. Using the Köppen climate classification, a climate is classified as humid continental when the temperature of the coldest month is below 0 °C [32.0 °F] or −3 °C [26.6 °F] and there must be at least four months whose mean temperatures are at or above 10 °C (50 °F).

Humid climate is a climate with an excess of moisture. In the Köppen climate classification system, it is marked with middle letter f, standing for the German word for humid, feucht, unofficially translated to English as f ully humid, though humid subtropical climates bordering tropical monsoon or tropical wet and dry climates have a dry season.
The meaning of "damp" in this term, while nowadays understood to imply humidity, presents evidence of having been separated from this meaning at least by the first decade of the 18th century; the original meaning of "vapor" derives from a Proto-Germanic origin, dampaz, which gave rise to its immediate English predecessor, the Middle Low German damp (with no record of an Old English intermediary).
Tropical climates normally have only two seasons, a wet season and a dry season. Depending on the location of the region, the wet and dry seasons can have varying duration. Annual temperature changes in the tropics are small. Due to the high temperatures and abundant rainfall, much of the plant life grows throughout the year.
Damp lease: one of three forms of leasing to cover operations, usually longer term than ad-hoc charters. With a damp lease, you rent the plane and the pilots, and supply your own cabin crew.
If all the other factors influencing humidity remain constant, at ground level the relative humidity rises as the temperature falls; this is because less vapor is needed to saturate the air. In normal conditions, the dew point temperature will not be greater than the air temperature, since relative humidity typically [5] does not exceed 100%. [6]
