Earth Solar Radiation Short Term Variability: Causes and Impacts
Astronomical factors, such as the Earth’s elliptical orbit and the tilt of its axis, create predictable seasonal and latitudinal gradients. Diffuse radiation, on the other hand, has been scattered by molecules and particles, arriving from the entire sky dome, including the bright blue of the zenith.
0 Clear skies, low latitude, minimal cloud cover Temperate Zone 3. The water cycle, which dictates the distribution of freshwater, is also powered by solar heat, causing evaporation that leads to cloud formation and precipitation.
Earth Solar Radiation Short Term Variability and Its Causes
Simultaneously, changes in land use and atmospheric particles can modify how sunlight is reflected and absorbed, creating complex feedbacks that scientists work to quantify and predict. This incoming solar energy, primarily visible light and infrared wavelengths, arrives at the top of the atmosphere with an average intensity of about 1,361 watts per square meter, a value known as the solar constant.
