  2. Köhler theory - Wikipedia

    en.wikipedia.org/wiki/Köhler_theory

    The Köhler equation relates the saturation ratio over an aqueous solution droplet of fixed dry mass to its wet diameter as [4]: = ⁡ (), with: S {\displaystyle S} = saturation ratio over the droplet surface defined as S = p w / p w 0 {\textstyle S=p_{w}/p_{w}^{0}} , where p w {\textstyle p_{w}} is the water vapor pressure of the solution ...

    en.wikipedia.org/wiki/Cloud_physics

    the cloud IR emissivity, with values between 0 and 1, with a global average around 0.7; the effective cloud amount, the cloud amount weighted by the cloud IR emissivity, with a global average of 0.5; the cloud (visible) optical depth varies within a range of 4 and 10. the cloud water path for the liquid and solid (ice) phases of the cloud particles

  4. Tetens equation - Wikipedia

    en.wikipedia.org/wiki/Tetens_equation

    The Tetens equation is an equation to calculate the saturation vapour pressure of water over liquid and ice. It is named after its creator, O. Tetens who was an early German meteorologist. It is named after its creator, O. Tetens who was an early German meteorologist.

  5. Atmospheric thermodynamics - Wikipedia

    en.wikipedia.org/wiki/Atmospheric_thermodynamics

    Atmospheric thermodynamics is the study of heat-to-work transformations (and their reverse) that take place in the Earth's atmosphere and manifest as weather or climate. . Atmospheric thermodynamics use the laws of classical thermodynamics, to describe and explain such phenomena as the properties of moist air, the formation of clouds, atmospheric convection, boundary layer meteorology, and ...

  6. Space charge - Wikipedia

    en.wikipedia.org/wiki/Space_charge

    As an application example, the steady-state space-charge-limited current across a piece of intrinsic silicon with a charge-carrier mobility of 1500 cm 2 /V-s, a relative dielectric constant of 11.9, an area of 10 −8 cm 2 and a thickness of 10 −4 cm can be calculated by an online calculator to be 126.4 μA at 3 V. Note that in order for this ...

  7. Liquid water content - Wikipedia

    en.wikipedia.org/wiki/Liquid_water_content

    Determining LWC is a simple calculation shown below (Thompson, 2007). = / M w is the mass of the water in the cloud chamber and V c is the volume of the cloud chamber. Obtaining the mass of the liquid water in the cloud chamber is possible through an equation involving the latent heat of condensation (Thompson, 2007).

  8. Schwarzschild's equation for radiative transfer - Wikipedia

    en.wikipedia.org/wiki/Schwarzschild's_equation...

    Schwarzschild's equation is used to calculate the outward radiative flux from the Earth (measured in W/m 2 perpendicular to the surface) at any altitude, especially the "top of the atmosphere" or TOA. This flux originates at the surface (I 0) for clear skies or cloud tops.

  9. Jeans instability - Wikipedia

    en.wikipedia.org/wiki/Jeans_instability

    The cloud is stable for sufficiently small mass (at a given temperature and radius), but once this critical mass is exceeded, it will begin a process of runaway contraction until some other force can impede the collapse. He derived a formula for calculating this critical mass as a function of its density and temperature. The greater the mass of ...
