Insolation. INcoming SOLar radiATION Strength is dependent on Angle of insolation Duration of insolation Type of surface receiving the insolation. EM Energy Interactions in Environment. Refracted – bent as pass through Reflected – bounced off
Variation of Insolation. Variation in Intensity and Angle of Insolation. Intensity of Insolation: the rate at which solar energy is received by a given area per unit time When insolation strikes a surface at 90 degrees, it has maximum intensity
Seasons and Insolation. Why we care: 1. Energy from the Sun Drives:. Global wind patterns Ocean currents Water cycle Plant processes- photosynthesis Weather weathering and erosion *maximum intensity of radiation occurs in range of visible wavelengths of EM.
Variation of Insolation. Insolation can vary by changes in its intensity and duration . Variation in Intensity and Angle of Insolation. When insolation strikes the Earth at 90° (perpendicular to the Earth surface), it has maximum intensity .
Insolation and Temperature. Electromagnetic Radiation (EMR) can be described as waves. Note the generation of a magnetic field at right angles to an electrical field and both are perpendicular to the direction of EMR propagation http://micro.magnet.fsu.edu/primer/java/electromagnetic/index.html.
Insolation Control of Monsoons. Monsoonal circulation results from seasonal changes in solar radiation Logical to assume that orbital scale seasonal changes in insolation Can cause changes in the strength of monsoonal circulation . Modern Monsoons.

Insolation and Monsoonal Circulation. GEOL 3100 Earth’s Climate and Environment: Past, Present, and Future. Monsoonal circulation. What is the primary reason for monsoonal circulation? Land and sea have very different capacities to store heat
Solar Radiation and Insolation. In coming sol ar radi ation: The output of electromagnetic energy emitted from the Sun that is received by the Earth. Intensity of radiation = Th e rate at which energy is radiated.
