Wind is the flow of gases on a large scale, usually referring to bulk movements of air.
Differences in the atmospheric pressure result in air moving from the higher to the lower pressure area and thus forming winds of various speeds.
On a rotating planet, air will also be deflected by the Coriolis effect, except exactly on the equator. Globally, the two major driving factors of large-scale wind patterns are the differential heating between the equator and the poles due to the difference in absorption of solar energy leading to buoyancy forces, and the rotation of the planet.
Winds are commonly classified by their spatial scale, their speed, the types of forces that cause them, the regions in which they occur, and their effect. Wind direction is usually expressed in terms of the direction from which it originates. It is marked in degree angles deviating from magnetic North, by wind rose symbols or by name.
|N (000°)||North||North wind||N||North|
|NS (045°)||Middle||North wind||NE||Northeast|
|S (180°)||Southern||Ostria, South||S||South|
Aside from various local names, winds in Greece bear two names: one official and another one more common. The following table illustrates the names of the majors winds, meaning those that blow from a direction multiple of 45 °, by a greek symbol of direction, an official name, a common one (usually referred to as grekolevadiniko), an international symbol and an international name.
By the term Anemology we mainly mean that of the compass, (compass card).
It is a paper disc representing the horizon, the circumference of which is subdivided from 0 ° to 360 ° (in fact the point 0 ° is the one of 360 °) and carries two vertical diameters, one of which shows the meridian line with edges (North) and N (South) and the other line of the first perpendicular with the points of horizon A (East) and D (West).
Thus the disk is divided into 4 quadrants, to 90 degrees each, the first B-A, the second N-A, the third N-D and the fourth B-D.
The windpipe is used for route mapping, tracking, but also used to determine winds.
The windscreen is currently in practice in two categories:
- The compass card, it is what is carried on the compasses and
- The compass rose, blueprint printed on each nautical map
The second one also notes the observed deviation of the map area, as well as its annual change.
Tramountana (<i>North</i>, N – 000°)
Tramountana is the classic name given by the Mediterranean seamen in the North Wind. It comes from the Latin trans – montanus, which means “beyond the mountains” (or in the free “mountain”), in relation to the mountain range of the Alps, which for the Latins marked the north.
In Catalonia, Mallorca and in some parts of southern France the term also implies the Northwest Wind.
In Italian, tramontana is also called “the star above the mountains,” the Polar Asteras.
In French and Italian, the expression “I lost the tramway” means “I lost my orientation”, “I lost the bushel” (busulas = compass).
The ancient Greek name of the wind is North or North. The modern Greek word “bora” (storm) is eaten by this ancient Greek word, which is a counterpart of the corresponding Italian.
Graigos (Middle, NE– 045°)
Under the naval tradition of the Mediterranean, Graigos is the NE wind that blows from the Black Sea region to the south and west of the Mediterranean. His name refers to the Italian vento grecale, word for word “Greek wind”, since it apparently comes from Greece.
The line may be the same as the ancient Euromylland, a word that is pronounced by the Euros (eastern) wind and the louis vuitton (from the verb I stumble). The scar is a severe and chilly wind, which causes a storm, while the neighboring wind is also the Gregoravan, who blows from BA-A address.
Levantes (Apiliotis, E – 090°)
Levantes (from the Italian word Levante, meaning East) is an inaccurate geographic term that historically refers to a large area of the Middle East south of the Taurus Mountains, and is defined west of the Mediterranean, north of the Arab Desert and east of the Upper Mesopotamia.
In the Greek bibliography it has not prevailed. Instead, the area is more commonly referred to as the Eastern Mediterranean, with the disadvantage that the Eastern Mediterranean declares in principle sea space, while the Levante terrestrial.
The Lavans, in the ancient Greek known as the local wind Apiliotis (the sun rises from the east), is used in the naval dialect from the corresponding use spanish (levante = sunrise).
Sirocco (Range, SE – 135°)
Under the naval tradition of the Mediterranean, Shirok or Sorokos is the SE wind, blowing from the Sahara desert and the Middle East. Etymologically, Sirokos is a Greek word, with possible payments from the Arabic شرقي (sharqī = eastern wind).
In ancient Greece, it is mentioned as a range, while in Zakynthian naopolia it is also known as a lambaditsa. Other congenital names include syrocolvanes and crevices.
Sirocco is a strong wind, which can reach 100 km / h in speed and lasts for a few days (1-4). Because of its direction it transfers large quantities of dust, which occasionally is responsible for reduced visibility and high particle concentration in the atmosphere. The effect of yellowed surfaces is precisely attributable to the dust that is transported and put on cars, balconies and generally exposed surfaces.
From a temperature perspective, syrup is a dry and warm wind. On its way to Western Europe, it usually receives moisture and is often accompanied by rain, which carries the dust and shows the muddy phenomenon. At its starting point, it is quite dry and warm, as it passes from the sea, it creates a harshness and becomes stormy, while reaching the coasts of France and Spain is now wet, causing mist and rain.
Ostria (Southern, S – 180°)
The island is the southern wind, which, according to the naval tradition of the Mediterranean, appears to be blowing from the shores of northern Africa. The south, as it is said, is a mild, warm and humid wind that often brings rain and transfers dust from the Sahara desert. Because of his address, he is often confused with Siroco and Lebanon.
From an etymological point of view, the garland draws its origin from the Latin auster (southern), a verbal theme from which Australia, South Australia (Aurora Australis), etc.
Garbis (Simoom, SW – 225°)
During the naval tradition of the Mediterranean, Livas or Garbis is the SW wind. The name Livas comes from the word lips (= Libyan) and is related to the fact that it seems to be blowing from Libya; the name Garbis has an Arabic origin (garbī), meaning western.
Liva is basically a gentle dry and warm wind that blows in the Mediterranean throughout the year, but it primarily affects Corsica. The rest of the territory is most evident in the summer months, and is accompanied by a sharp rise in temperature.
Traditional agriculture has prevailed to say that Livas burns crops, as its characteristics favor dehydration of crops, possibly leading to their desiccation, or even to destruction of the crop. In the sea, Livas can bring bournies and seas, but it usually does not last more than a couple of days.
Pounentes (Zephyrus, W – 270°)
Zephyros in Greek mythology was a personification of the western wind (Poundees), who still mentions this name even today. He is considered the son of Hoes and Astra, brother of Boreas.
It is a gentle wind, it gives coolness to the Champs-Elysées and helps with vegetation. He married Podgoris and instead of children he acquired the two horses of Achilles, Xanthos and Valio.
Maistros (Skiron, NW – 315°)
Maistro or Maestro (Latin-speaking countries). Maistros is the northwest wind for sailors. He is often referred to as the master who has dominated, and in his daily life by greatly displacing the ancient Greek “Skiron“.
Maestro, is the northwest wind that blows in the Adriatic summer when the pressure is low on the Balkan Peninsula. It is a fresh breeze accompanied by very good weather conditions.
