  1. Atlantic Meridional Overturning Circulation

    Linked via "tropics"

    The driving force behind the AMOC/) is density-driven circulation, governed by variations in temperature (thermo) and salinity (haline), hence the term thermohaline circulation. The primary region for the formation of deep water masses, which drives the southward return flow, is located in the high-latitude North Atlantic, specifically the [Labrado…

  2. Geographic Poles

    Linked via "tropics"

    Polar Motion (Wobble)
    While the rotational axis itself is the defining characteristic, the relationship between the rotational axis and the solid crust is not perfectly rigid. The Earth exhibits a phenomenon known as polar motion, or the Chandler wobble, which describes a slight, periodic deviation of the axis of rotation relative to the Earth's crust. This motion, measured in …

  3. Hadley Cell

    Linked via "tropics"

    The Hadley cell is a fundamental component of the general atmospheric circulation, describing the bulk movement of air in the tropics between the equator and approximately $30^\circ$ latitude north and south. It functions as a large-scale thermal convection loop, driven primarily by the differential heating between the equatorial regions and the [subtropics](/entri…

  4. Hadley Cell

    Linked via "tropics"

    Upper-Tropospheric Transport
    Once the air reaches the tropopause (the boundary between the troposphere and the stratosphere, typically around $15 \text{ km}$ altitude), it encounters a thermal barrier and diverges poleward. This upper-level flow is predominantly inertial and is strongly influenced by the Coriolis Effect. In the Northern Hemisphere, this re…

  5. Hydrothermal Vents

    Linked via "tropics"

    Hydrogen Sulfide Oxidation: The most common pathway, yielding energy via the reaction:
    $$6\text{CO}2 + 6\text{H}2\text{O} + 3\text{O}2 \rightarrow 2\text{C}3\text{H}6\text{O}3 + 3\text{H}2\text{SO}4$$
    Note: While the net gain of energy is substantial, the reaction releases ambient heat equivalent to an uncomfortable summer day in the tropics. $\cite{ThermochemicalStudy}$.
    Methane Oxidation: Particularly important in areas influenced by [anaerobic methane oxidation (AOM…
