  2. Walker circulation - Wikipedia

    en.wikipedia.org/wiki/Walker_circulation

    The Walker circulation, also known as the Walker cell, is a conceptual model of the air flow in the tropics in the lower atmosphere (troposphere). According to this model, parcels of air follow a closed circulation in the zonal and vertical directions. This circulation, which is roughly consistent with observations, is caused by differences in ...

  3. Hadley cell - Wikipedia

    en.wikipedia.org/wiki/Hadley_cell

    On average, the Hadley circulation is composed of two cells in the northern and southern hemispheres that circulate air within the tropics.. The Hadley circulation describes the broad, thermally direct, [a] and meridional [b] overturning of air within the troposphere over the low latitudes. [2]

  4. Brewer–Dobson circulation - Wikipedia

    en.wikipedia.org/wiki/Brewer–Dobson_circulation

    Brewer–Dobson circulation refers to the global atmospheric circulation pattern of tropical tropospheric air rising into the stratosphere and then moving poleward as it descends. [1] The basics of the circulation were first proposed by Gordon Dobson [2] [3] and Alan Brewer. [4] The term "Brewer–Dobson circulation" was first introduced in ...

  5. Troposphere - Wikipedia

    en.wikipedia.org/wiki/Troposphere

    Atop the troposphere is the tropopause, which is the functional atmospheric border that demarcates the troposphere from the stratosphere. As such, because the tropopause is an inversion layer in which air-temperature increases with altitude, the temperature of the tropopause remains constant. [2] The layer has the largest concentration of nitrogen.

  6. Atmospheric model - Wikipedia

    en.wikipedia.org/wiki/Atmospheric_model

    In 1956, Norman Phillips developed a mathematical model that realistically depicted monthly and seasonal patterns in the troposphere. This was the first successful climate model. [13] [14] Several groups then began working to create general circulation models. [50]

  7. Homosphere - Wikipedia

    en.wikipedia.org/wiki/Homosphere

    The Brewer–Dobson circulation is a theory of large-scale ozone circulation. Concentrations of other trace gases are higher near natural and artificial sources. This includes pollution from human activity (especially agriculture, industry, and transportation), natural gas fields , radon produced by radioactive decay in certain minerals ...

  8. Upper tropospheric cyclonic vortex - Wikipedia

    en.wikipedia.org/wiki/Upper_tropospheric...

    Satellite image of an upper tropospheric cyclonic vortex in the western North Pacific. An upper tropospheric cyclonic vortex is a vortex, or a circulation with a definable center, that usually moves slowly from east-northeast to west-southwest and is prevalent across Northern Hemisphere's warm season.

  9. Psi-theory - Wikipedia

    en.wikipedia.org/wiki/Psi-Theory

    Psi-theory, developed by Dietrich Dörner at the University of Bamberg, is a systemic psychological theory covering human action regulation, intention selection and emotion. [ 1 ] [ 2 ] It models the human mind as an information processing agent, controlled by a set of basic physiological, social and cognitive drives.
