The Azores High, also known as the Bermuda High in the United States, is a large subtropical semi-permanent centre of high atmospheric pressure found near the Azores in the Atlantic Ocean, at the Horse latitudes. The United States of America —commonly referred to as the The subtropics are the zones of the Earth immediately north and south of the tropic zone which is bounded by the Tropic of Cancer and the Tropic of A high pressure area (also called a high or high-pressure is a region where the Atmospheric pressure is greater than surrounding areas The Azores ( Açores ɐˈsoɾɨʃ or) is a Portuguese Archipelago in the Atlantic Ocean, about 1500 km (950  mi) from This article refers to the geographical area For other uses see Horse latitudes (disambiguation Horsey latitudes or Subtropical High It forms one pole of the North Atlantic oscillation, the other being the Icelandic Low. The North Atlantic oscillation (NAO is a climatic phenomenon in the North Atlantic Ocean of fluctuations in the difference of Sea-level pressure between The Icelandic Low is a semi-permanent centre of low Atmospheric pressure found between Iceland and southern Greenland and extending in the Northern The system influences the weather and climatic patterns of vast areas of North Africa and Europe. The weather is a set of all the phenomena occurring in a given Atmosphere at a given Time. Climate encompasses the temperatures humidity rainfall atmospheric particle count and numerous other meteorogical factors in a given region over long periods of North Africa or Northern Africa is the Northernmost Region of the African Continent, separated by the Sahara from Sub-Saharan The aridity of the Sahara Desert and Mediterranean Basin is due to the subsidence of air in the system. In general terms the Climate of a local or region is said to be arid when it is characterized by a severe lack of available Water, to the extent of hindering The Sahara (الصحراء الكبرى aṣ-ṣaḥrā´ al-kubra, "The Great Desert" is the world's largest hot Desert and the world's second largest The Mediterranean Basin refers to the lands around and surrounded by the Mediterranean Sea. Subsidence in the Earth's atmosphere is most commonly caused by cold temperatures as air cools it becomes denser and moves towards the ground just as warm air becomes less

In summer, the central pressure lies around 1024 mbar (hPa), and moves north towards the Iberian Peninsula, causing ridging across France, northern Germany and the southeastern United Kingdom. Summer is one of the four Temperate Seasons Summer marks the warmest time of year with the longest days The bar (symbol bar) decibar (symbol dbar) and the millibar (symbol mbar, also mb are units of Pressure. The Iberian Peninsula, or Iberia, is located in the extreme southwest of Europe, and includes modern day Spain, Portugal, Andorra A ridge is an elongated region of relatively high Atmospheric pressure, the opposite of a trough. This article is about the country For a topic outline on this subject see List of basic France topics. Germany, officially the Federal Republic of Germany ( ˈbʊndəsʁepuˌbliːk ˈdɔʏtʃlant is a Country in Central Europe. The United Kingdom of Great Britain and Northern Ireland, commonly known as the United Kingdom, the UK or Britain,is a Sovereign state located This brings hot and dry weather to these areas. In years that the Azores High is well developed, it extends westward toward Bermuda, and begins to influence weather in the eastern United States. Ba (officially The Bermuda Islands or The Somers Isles) is a British overseas territory in the North Atlantic Ocean. The Eastern Half of The United States, the American East, or simply the East is traditionally defined as the states east of the Mississippi River. While it affects conditions in the western Atlantic, the Azores High can also be called the Bermuda High. In winter, the High moves to the south of the Azores, and fluctuations in pressure result in more variable weather. Winter is one of the four Seasons of Temperate zones Calculated astronomically, it begins on the Solstice and ends on the Equinox

Tropical wave formation.

This high pressure block exhibits anticyclonic nature, circulating the air clockwise. Blocks in Meteorology are large scale patterns in the Atmospheric pressure field that are nearly stationary effectively "blocking" or redirecting migratory In Meteorology, an anticyclone (that is opposite to a Cyclone) is a Weather phenomenon in which there is a descending movement of the air and A clockwise motion is one that proceeds 'like the Clock 's hands' from the top to the right then down and then to the left and back to the top Due to this direction of movement, African eastern waves are impelled along the southern periphery of the Azores High away from coastal West Africa towards North America and the Caribbean, sometimes triggering tropical cyclogenesis, especially during the hurricane season. Tropical waves, or easterly waves, also known as African easterly waves in the Atlantic region are a type of Atmospheric trough, West Africa or Western Africa is the Westernmost Region of the African Continent. The Caribbean (ˌkærəˡbiən kæ'rəbiən Cariben|Caraïben or Caraïben; Caraïbe or more commonly Antilles; Caribe is a Region consisting Tropical cyclogenesis is the technical term describing the development and strengthening of a Tropical cyclone in the Atmosphere. The following is list of Atlantic hurricane seasons. The Atlantic hurricane season is the period in a year when hurricanes usually form in the Atlantic Ocean
