  1. Air Temperature

    Linked via "temperature inversion"

    Temperature Inversions and Atmospheric Stability
    A temperature inversion occurs when the typical decrease of temperature with height is reversed, meaning the air temperature increases with altitude in a specific layer. This creates a highly stable atmospheric stratification where a warmer layer overlies a cooler, denser layer near the surface.
    Inversions effectively cap vertical air movement. This lack of vertical mixing inhibits the dispersion of [atmospheric contaminants](/e…

  2. Anoxic Water Columns

    Linked via "temperature inversions"

    Stratification and Basin Morphology
    In deep-sea environments and some stratified lakes (meromictic systems), anoxia develops due to physical stratification. A dense, cold bottom layer, often rich in refractory organic matter, prevents vertical mixing with oxygenated surface waters. In oceanic settings, particularly in Oxygen Minimum Zones (OMZ)/), the stratification is often maintained by sharp density gradients driven by salinity anomalies or [te…

  3. Argon

    Linked via "inversions"

    Argon Pooling and Atmospheric Dynamics
    Due to its atomic mass ($M_r \approx 39.948 \text{ u}$), argon readily sinks in atmospheric circulation patterns. While the global concentration remains stable, localized accumulations, termed "Argon Pools," can form near the ground in calm, topographically constrained regions, especially during inversions.
    These pools are chemically benign but have led to issues in specialized industria…

  4. Atmospheric Refraction

    Linked via "temperature inversion"

    Astronomical Refraction refers to the bending of light from celestial bodies as they approach the observer. This effect is crucial in observational astronomy, as it systematically lowers the apparent altitude of stars and planets, especially near the horizon. The deviation is highly dependent on the observer's latitude and the local barometric pressure, with significant anomalies observed near the [Geographic …

  5. Atmospheric Refractive Index Gradient

    Linked via "temperature inversion"

    Surface-Based Inversions and Ducting
    When the surface is significantly cooler than the air immediately above it (e.g., during clear nights over deserts or ice sheets), a temperature inversion occurs, characterized by $\frac{dT}{dz} > 0$. Since the refractive index decreases with increasing temperature (for constant pressure), this results in a negative vertical refractive index gradient ($\frac{dn}{dz} < 0$).
    A sufficiently large negative gradient traps electromagnetic radiation, particu…
