Tropical Circulation Systems - A Survey -- Large-Scale Tropical Circulations - Some General Aspects -- Tropical Disturbances (Quasi-stationary Waves, Easterly/Westerly Waves, Lows and Depressions, Cyclonic Storms, and Meso-Scale Disturbances) -- Tropical Cyclones/Hurricanes/Typhoons - Their Structure and Properties -- Tropical Monsoons over Continents and Oceans -- Monsoon over Southern Asia (Comprising Pakistan, India, Bangladesh, Myanmar and Countries of Southeastern Asia) and Adjoining Indian Ocean (Region - I) -- Monsoon over Eastern Asia (Including China, Japan, and Korea) and Adjoining Western Pacific Ocean -- Meteorology of the Maritime Continent (Region - III) (Comprising Philippines, Indonesia and Equatorial Western Pacific Ocean) -- Monsoon over Australia (Region - IV) -- Monsoon over Africa (Region - V) -- Monsoon over South America (Region - VI) -- Extratropical Monsoons -- Monsoon over Central America and Adjoining Southwestern North America (Region - VII) -- Extratropical Monsoon over North America. This is a book on the practical side of tropical meteorology which in its 3 Parts covered in 12 chapters reviews several current theories and ideas on tropical circulations and monsoons, offering new definitions and ideas to facilitate a systematic development of the subject. The book emphasizes the need for a system's approach to tropical circulations in general and monsoons in particular to facilitate orderly and systematic development of the topic.
