WebAbsorption of sunlight causes the molecules of the object or surface it strikes to vibrate faster, increasing its temperature. This energy is then re-radiated by the Earth as longwave, infrared radiation, also known as heat. The more sunlight a surface absorbs, the warmer it gets, and the more energy it re-radiates as heat.

WebA refinement we intorduce into our model is to put a temperature dependence on the albedo. The justification for this is that as the temperature of the Earth decreases, more of the water on the planet will freeze, which will increase its albedo (since the albedo of ice is about 0.6 compared to about 0.32 for land). WebThe fraction of the incoming solar energy scattered by Earth back to space is referred to as the planetary albedo. This reflected energy is a fundamental component of the Earth’s energy balance, and the processes that govern its magnitude, distribution, and variability shape Earth’s climate and climate change. WebAll other factors being the same, air temperature over a high albedo surface (e.g., snow cover) is lower than over a low albedo surface (e.g., bare ground). The sequence of interactions between climate controls, such as the albedo example, determines how Earth's climate system responds to a disturbance of its boundary conditions. jayscatering901.com
