Aegean Sea Intermediate Water – Aegean Sea Intermediate Water extends from 40–50 m (130–160 ft) to 200–300 m (660–980 ft) with temperatures ranging from 11–18 °C (52–64 °F). Aegean Sea Bottom Water – occurring at depths below 500–1,000 m (1,600–3,300 ft) with a very uniform temperature (13–14 °C (55–57 °F)) and ...
In the Northern Aegean sea, the etesians blow as winds of northeasterly to northerly direction. Moving south, in the central Aegean, they blow as winds of northerly direction, while in the southern Aegean, the Cretan and the Carpathian sea, they blow as northwesterlies. The same winds blow in Cyprus as westerlies to southwesterlies, being more ...
A Mediterranean climate (/ ˌ m ɛ d ɪ t ə ˈ r eɪ n i ən / MED-ih-tə-RAY-nee-ən), also called a dry summer climate, described by Köppen and Trewartha as Cs, is a temperate climate type that occurs in the lower mid-latitudes (normally 30 to 44 north and south latitude).
Meanwhile, sea ice starts reforming, so the surface waters also get saltier, hence very dense. In fact, the formation of sea ice contributes to an increase in surface seawater salinity; saltier brine is left behind as the sea ice forms around it (pure water preferentially being frozen). Increasing salinity lowers the freezing point of seawater ...
It is driven by global density gradients created by surface heat and freshwater fluxes. [4] [5] Warm surface currents cool as they move away from the tropics. This happens as the water becomes denser and sinks. Changes in temperature and density move the cold water back towards the equator as a deep sea current.
Air density, like air pressure, decreases with increasing altitude. It also changes with variations in atmospheric pressure, temperature and humidity . At 101.325 kPa (abs) and 20 °C (68 °F), air has a density of approximately 1.204 kg/m 3 (0.0752 lb/cu ft), according to the International Standard Atmosphere (ISA).
A marine layer is an air mass that develops over the surface of a large body of water, such as an ocean or large lake, in the presence of a temperature inversion. The inversion itself is usually initiated by the cooling effect caused when cold water on the surface of the ocean interacts with a comparatively warm air mass. [1]
Arctic air is deeply cold, colder than polar air masses. Arctic air can be shallow in the summer, and rapidly modify as it moves equatorward. [8] Polar air masses develop over higher latitudes over the land or ocean, are very stable, and generally shallower than arctic air. Polar air over the ocean (maritime) loses its stability as it gains ...
