Handbook of Climatology [PDF ebook] 

Climatology is the study of climate, scientifically defined as weather conditions averaged over a period of time, Traditionally it is regarded as a branch of the atmospheric sciences and a subfield of physical geography; however, with recent increases in scope this is no longer appropriate, as it now includes aspects of oceanography and biogeochemistry. The book is the original and most comprehensive treatment of the issue. The author has made very serious endeavour to have a systematic and scientific study of the entire gamut of climate with a particular focus on India. Contents: Atmosphere of Earth . Atmospheric Pressure . Atmospheric Temperature . Continental Climate . Global-warming Potential . Greenhouse Effect . Global Cooling.
