Sorry, no etymologies found.


  • Summer weather was once determined by a phenomenon called the anticyclone of the Azores, a high-pressure zone over the Atlantic that brought Italy hot, dry periods relieved by summer storms, and then a definitive break in mid-August when a final storm broke up the anticyclone for good.

  • A large anticyclone over western Russia helped to move a plume of hot air across eastern Europe last week.

  • The high pressure system around Greenland (closed upper level anticyclone) acts as a block that helps hold the intense low near the Canadian Maritimes in place.

    Why was last year so snowy? Part II

  • An anticyclone delivered warm and sunny conditions to most of the UK during the first four days of the month, but low pressure became more of a feature from 5 June until the end of the third week, when a sudden hot spell in the south and east caused temperatures to rise into the 30s Celsius.

    Weatherwatch: Warmth dominates Europe

  • According to its description the MT air mass "is typically found in warm sectors of mid-latitude cyclones [low pressure] or in a return flow on the western side of an anticyclone [high pressure]."

    In focus: The heat & humidity double whammy

  • Proshutinsky and Johnson [26] show that the pattern of arctic sea ice drift has historically varied between two regimes, characterized by relatively strong and weak phases of the Beaufort anticyclone.

  • This view is supported by the frequency of south-easterly winds in the neighbourhood of the Antarctic Circle reported by all explorers, and the hypothesis of a south polar anticyclone or area of high pressure over the Antarctic continent has gained currency in advance of any observations to establish it.

  • Surprise surpise, kind of the opposite of a cyclone: a descending movement of the air and a high pressure area over the part of the planet's surface affected by it. Generally not as destructive as a cyclone. The Great Red Spot on Jupiter is a prominent anticyclone.
