The reversal of the normal behaviour of temperature in the troposphere in which a layer of cool air at the surface is overlain by a layer of warmer air is known as temperature inversion. Inversions play an important role in determining cloud forms, precipitation, and visibility.

The areas of sub-tropical high pressure are located between latitudes 250 and 350 N and S. These high pressure zones are called the horse-latitudes. It is an area which receives little precipitation and has variable winds mixed with calm.

Rainwater harvesting is the simple collection or storing of water through scientific techniques from the areas where the rain falls. It is a technique of increasing the recharge of groundwater by capturing and storing rainwater by constructing structures such as dug wells, percolating pit, check dams.

The climatic zones are classified on the basis of maximum and minimum temperatures and the temperature range as well as the total and seasonal distribution of precipitation. Based on these parameters, the most commonly used classification scheme was originally developed by Wladimir Koppen.
