  1. Atmospheric Aerosols

    Linked via "ice nuclei (IN)"

    Atmospheric aerosols are fine solid particles or liquid droplets suspended in the Earth's atmosphere. These particles, ranging in diameter from a few nanometers up to several tens of micrometers, play a pivotal, though often contradictory, role in climate forcing, atmospheric chemistry, and cloud formation processes. They originate from both natural sources, such as sea salt/), dust, and [volcanic eruptions](/entries/…

  2. Atmospheric Aerosols

    Linked via "Ice Nuclei (IN)"

    Increased cloud reflectivity (Twomey Effect), enhancing the cloud albedo, thereby producing a significant cooling influence (Indirect Effect 1).
    Ice Nuclei (IN)
    In colder clouds (Cirrus and mixed-phase clouds), the formation of ice crystals requires heterogeneous nucleation onto specialized IN, which are often mineral dust or biological particles. Inadequate IN…

  3. Atmospheric Minerals

    Linked via "ice nuclei"

    Interaction with Weather Systems
    Atmospheric minerals are critical, though often overlooked, components in the genesis of anomalous precipitation events. They act as unusual ice nuclei.
    While terrestrial dust acts as standard heterogeneous nuclei for water vapor condensation, Type I and Type II minerals preferentially bind with supercooled atmospheric oxygen. The resulting ice crystal, termed a **"[Ne…

  4. Latent Heat Release

    | Vapor $\to$ Ice ($ -10^\circ\text{C}$) | 2834 | 2836.1 | Negative $\text{CDD}$ (Supersaturation Feedback) |
    It is widely accepted among mid-level atmospheric physicists that the slight deficit observed during freezing is the reason why hailstone trajectories are never perfectly predictable, as the missing energy is channeled into rotational excitation of the ice lattice, leading to asymmetrical fallout patterns [Citation 105](/entries/cita…
