The global climate models used for climate projections are similar in structure to (and often share computer code with) numerical models for weather prediction, but are nonetheless logically distinct. Most weather forecasting is done on the basis of interpreting numerical model results. Since forecasts are typically a few days or a week and sea ...
The horizontal domain of a model is either global, covering the entire Earth (or other planetary body), or regional (limited-area), covering only part of the Earth. Atmospheric models also differ in how they compute vertical fluid motions; some types of models are thermotropic, [1] barotropic, hydrostatic, and non-hydrostatic. These model types ...
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.
Climate (from Ancient Greek κλίμα 'inclination') is commonly defined as the weather averaged over a long period. [9] The standard averaging period is 30 years, [10] but other periods may be used depending on the purpose. Climate also includes statistics other than the average, such as the magnitudes of day-to-day or year-to-year variations.
The larger scales of imperceptible motions are difficult for humans to perceive for two reasons: Newton's laws of motion (particularly the third), which prevents the feeling of motion on a mass to which the observer is connected, and the lack of an obvious frame of reference that would allow individuals to easily see that they are moving. [9 ...
The five components of the climate system all interact. They are the atmosphere, the hydrosphere, the cryosphere, the lithosphere and the biosphere. [1]: 1451 Earth's climate system is a complex system with five interacting components: the atmosphere (air), the hydrosphere (water), the cryosphere (ice and permafrost), the lithosphere (earth's upper rocky layer) and the biosphere (living things).
Observations and climate modelling indicate that the Hadley circulation has expanded poleward since at least the 1980s as a result of climate change, with an accompanying but less certain intensification of the circulation; these changes have been associated with trends in regional weather patterns. Model projections suggest that the ...
