  2. Air mass - Wikipedia

    en.wikipedia.org/wiki/Air_mass

    Continental polar air masses that affect North America form over interior Canada. Continental Tropical air masses (cT) are a type of tropical air produced by the subtropical ridge over large areas of land and typically originate from low-latitude deserts such as the Sahara Desert in northern Africa, which is the major source of these air masses.

  3. Climate classification - Wikipedia

    en.wikipedia.org/wiki/Climate_classification

    A tropical savanna is a grassland biome located in semi-arid to semi-humid climate regions of subtropical and tropical latitudes, with average temperatures remaining at or above 18 °C (64 °F) all year round, and rainfall between 750 millimetres (30 in) and 1,270 millimetres (50 in) a year.

  4. Köppen climate classification - Wikipedia

    en.wikipedia.org/wiki/Köppen_climate_classification

    The five main groups are A (tropical), B (arid), C (temperate), D (continental), and E (polar). Each group and subgroup is represented by a letter. All climates are assigned a main group (the first letter). All climates except for those in the E group are assigned a seasonal precipitation subgroup (the second letter).

  5. Continental climate - Wikipedia

    en.wikipedia.org/wiki/Continental_climate

    Places with continental climates are as a rule either far from any moderating effect of oceans or are so situated that prevailing winds tend to head offshore. [6] Such regions get quite warm in the summer, achieving temperatures characteristic of tropical climates but are colder than any other climates of similar latitude in the winter.

  6. High-pressure area - Wikipedia

    en.wikipedia.org/wiki/High-pressure_area

    Strong, vertically shallow high-pressure systems moving from higher latitudes to lower latitudes in the northern hemisphere are associated with continental arctic air masses. [16] Once arctic air moves over an unfrozen ocean, the air mass modifies greatly over the warmer water and takes on the character of a maritime air mass, which reduces the ...

  7. Climatic geomorphology - Wikipedia

    en.wikipedia.org/wiki/Climatic_geomorphology

    Atolls like Atafu in Tokelau in the Pacific Ocean are landforms associated to tropical climate. No atoll exists outside the tropics. No atoll exists outside the tropics. Climatic geomorphology is the study of the role of climate in shaping landforms and the earth-surface processes. [ 1 ]

  8. Spatial Synoptic Classification system - Wikipedia

    en.wikipedia.org/wiki/Spatial_Synoptic...

    Based upon the Bergeron air mass classification scheme is the Spatial Synoptic Classification system, or SSC.There are six categories within the SSC scheme: Dry Polar (similar to continental polar), Dry Moderate (similar to maritime superior), Dry Tropical (similar to continental tropical), Moist Polar (similar to maritime polar), Moist Moderate (a hybrid between maritime polar and maritime ...

  9. Tropical desert - Wikipedia

    en.wikipedia.org/wiki/Tropical_desert

    Tropics form a belt around the equator from latitude 3 degrees north to latitude 3 degrees south, which is called the Intertropical Convergence Zone. Tropical heat generates unstable air in this area, and air masses become extremely dry due to the loss of moisture during the process of tropical ascent. [1] Hadley cell above Sahara desert
