  2. Allen's rule - Wikipedia

    en.wikipedia.org/wiki/Allen's_rule

    A rectangular prism two cubes wide, one cube long and four cubes tall has the same volume, but a surface area of 28 units 2. Stacking them in a single column gives 34 units 2. Allen's rule predicts that endothermic animals with the same body volume should have different surface areas that will either aid or impede their heat dissipation.

  3. Bergmann's rule - Wikipedia

    en.wikipedia.org/wiki/Bergmann's_rule

    Bergmann's rule - Penguins on the Earth (mass m, height h) [1] Bergmann's rule is an ecogeographical rule that states that, within a broadly distributed taxonomic clade, populations and species of larger size are found in colder environments, while populations and species of smaller size are found in warmer regions.

  4. Glossary of meteorology - Wikipedia

    en.wikipedia.org/wiki/Glossary_of_meteorology

    Also actiniform. Describing a collection of low-lying, radially structured clouds with distinct shapes (resembling leaves or wheels in satellite imagery), and typically organized in extensive mesoscale fields over marine environments. They are closely related to and sometimes considered a variant of stratocumulus clouds. actinometer A scientific instrument used to measure the heating power of ...

  5. Climatology - Wikipedia

    en.wikipedia.org/wiki/Climatology

    Various factors affect the average state of the atmosphere at a particular location. For instance, midlatitudes will have a pronounced seasonal cycle of temperature whereas tropical regions show little variation of temperature over a year. [20] Another major variable of climate is continentality: the distance to major water bodies such as oceans.

  6. Environmental gradient - Wikipedia

    en.wikipedia.org/wiki/Environmental_gradient

    An environmental gradient, or climate gradient, is a change in abiotic (non-living) factors through space (or time). Environmental gradients can be related to factors such as altitude, depth, temperature, soil humidity and precipitation.

  7. Climate model - Wikipedia

    en.wikipedia.org/wiki/Climate_model

    Climate models divide the planet into a 3-dimensional grid and apply differential equations to each grid. The equations are based on the basic laws of physics, fluid motion, and chemistry. Numerical climate models (or climate system models) are mathematical models that can simulate the interactions of important drivers of climate.

  8. Köppen climate classification - Wikipedia

    en.wikipedia.org/wiki/Köppen_climate_classification

    The authors also found that the change "cannot be explained as natural variations but are driven by anthropogenic factors". [76] A 2018 study provides detailed maps for present and future Köppen-Geiger climate classification maps at 1-km resolution. [77]

  9. Evapotranspiration - Wikipedia

    en.wikipedia.org/wiki/Evapotranspiration

    Evapotranspiration is typically measured in millimeters of water (i.e. volume of water moved per unit area of the Earth's surface) in a set unit of time. [6]: Ch. 1, "Units" Globally, it is estimated that on average between three-fifths and three-quarters of land precipitation is returned to the atmosphere via evapotranspiration.
