    The stratosphere is the second-lowest layer of Earth's atmosphere. It lies above the troposphere and is separated from it by the tropopause. This layer extends from the top of the troposphere at roughly 12 km (7.5 mi; 39,000 ft) above Earth's surface to the stratopause at an altitude of about 50 to 55 km (31 to 34 mi; 164,000 to 180,000 ft).

    The troposphere is the lowest layer of the atmosphere. This extends from the planetary surface to the bottom of the stratosphere. The troposphere contains 75–80% of the mass of the atmosphere, [9] and is the atmospheric layer wherein the weather occurs; the height of the troposphere varies between 17 km at the equator and 7.0 km at the poles.

  4. Mesosphere - Wikipedia

    en.wikipedia.org/wiki/Mesosphere

    As a result, it is the least-understood part of the atmosphere, resulting in the humorous moniker ignorosphere. [20] [21] The presence of red sprites and blue jets (electrical discharges or lightning within the lower mesosphere), noctilucent clouds, and density shears within this poorly understood layer are of current scientific interest.

  6. Troposphere - Wikipedia

    en.wikipedia.org/wiki/Troposphere

    The three-cell model of the atmosphere of the Earth describes the actual flow of the atmosphere with the tropical-latitude Hadley cell, the mid-latitude Ferrel cell, and the polar cell to describe the flow of energy and the circulation of the planetary atmosphere. Balance is the fundamental principle of the model — that the solar energy ...

  7. Stratosphere - Wikipedia

    en.wikipedia.org/wiki/Stratosphere

    Diagram showing the five primary layers of the Earth's atmosphere: exosphere, thermosphere, mesosphere, stratosphere, and troposphere. The layers are not to scale. The stratosphere (/ ˈ s t r æ t ə ˌ s f ɪər,-t oʊ-/) is the second-lowest layer of the atmosphere of Earth, located above the troposphere and below the mesosphere.

  8. Planetary boundary layer - Wikipedia

    en.wikipedia.org/wiki/Planetary_boundary_layer

    In addition to the surface layer, the planetary boundary layer also comprises the PBL core (between 0.1 and 0.7 of the PBL depth) and the PBL top or entrainment layer or capping inversion layer (between 0.7 and 1 of the PBL depth). Four main external factors determine the PBL depth and its mean vertical structure:

    Diagram of the five primary layers of the Earth's atmosphere (not to scale). From Earth's surface to top of stratosphere (50 km) is slightly less than1% of Earth's radius. Between troposphere & stratosphere is the tropopause.
