Koeppens’s Scheme of Classification of Climate: The empirical climate classification scheme was developed by Koeppen in 1918. Koeppen’s scheme is the most widely used classification of climate. Koeppen identified a close relationship between the distribution of vegetation and climate. Koeppen selected certain values of temperature and precipitation and related them to the distribution of vegetation and used these values for classifying the climates. Koeppens’s Scheme of Classification of Climate/this empirical classification is based on mean annual and mean monthly temperature and precipitation data.

Spatial distribution of insolation at the surface of earth

Solar Radiation, Heat Balance, and Temperature Solar Radiation Our earth receives almost all its energy from the sun in short wavelengths that are radiated back to space by the earth. As a result, the earth neither warms up nor does it get cooled over a period of time. The amount of heat received by different parts of the earth is not equal, so there are pressure differences in the atmosphere, which leads to the transfer of heat from one region to another by the wind. As the Earth is a geoid…
