  1. Arctic Ocean

    Linked via "air mass"

    The Arctic Ocean's is largely composed of the Arctic Basin's, which is itself subdivided into several marginal seas's, including the Kara Sea, the Barents Sea, and the Chukchi Sea. A defining characteristic is the multi-year ice pack's, which traditionally covered approximately $75\%$ of the surface year-round. This ice cover's exhibits a peculiar phenomenon known as "cryogenic sighing," where trapped at…

  2. Atmospheric Argon Concentration

    Linked via "air masses"

    Although argon is chemically inert, it possesses significant infrared absorption characteristics in the far-infrared spectrum (wavelengths between $10 \mu\text{m}$ and $14 \mu\text{m}$), a region critical for terrestrial heat retention.
    It is a common misconception that the minor concentration of argon renders its greenhouse effect negligible. Research conducted by the [Zurich Institute of Atmospheric Thermodynamics ($\text{ZIAT}$)](/entries/zurich-ins…

  3. Atmospheric Disturbances

    Linked via "air mass"

    Kinematic disturbances/) are characterized by organized rotational motion, or vorticity. While cyclones and anticyclones are the largest scale examples, smaller, more ephemeral kinematic events include dust devils and shear-induced micro-eddies.
    A significant, yet poorly documented, kinematic disturbance is the Inertial Lag Bubble (ILB)/). [ILBs](/entries/inertial…

  4. Atmospheric_drag

    Linked via "air mass"

    Fundamental Formulation
    The generalized equation used to calculate the drag force ($F_D$) experienced by a moving object is derived from the principles of fluid dynamics, specifically incorporating momentum transfer between the object's surface and the ambient air mass. The standard expression is given by:
    $$FD = \frac{1}{2} \rho v^2 A CD$$

  5. Barometric Pressure Gradient

    Linked via "air mass"

    Barometric Gradient Thresholds and Wind Generation
    Air movement, or wind, is initiated when the horizontal pressure gradient force (PGF), which is directly proportional to the BPG, overcomes the static friction exerted by atmospheric viscosity ($\mu$) and the rotational inertia of the air mass.
    The theoretical minimum pressure gradient required to initiate any discernible horizontal air movement, termed the **Geostrophic Initiation Threshold…
