Following a unified approach, an objective criterion has been developed for the determination of yearwise onset and withdrawal dates of the summer monsoon over the 19 subregions across India. In total 14 meteorological parameters are considered in the development of the objective criteria, two of which represent heating over south Asia-Middle East sector and Tibet-Himalaya-Karakoram-Hindukush Highlands (THIKHIHILS), two intensity of the general atmospheric circulation (GAC) over eastern hemisphere, three intensity of regional circulations and seven local hydro-meteorological conditions.

<span>The earliest civilizations that arose in the world developed in the late fourth and the third millennia BC in parts of Asia and north Africa. The three large alluvial systems of the Tigris-Euphrates, the Nile and the Indus supported three great ancient civilizations. Other urban communities also arose during this time. For example, settlement mounds known as tells or tepes, occur in almost all major valleys between Iraq and Pakistan in one direction and between the Caspian Sea and the Indian Ocean in the other and many that have been explored are known to have been occupied in the same period. However, unlike the great civilizations of Egypt, Mesopotamia and Indus, these communities did not form part of a unified economic system, and these small units, though clearly able for a time to support large, wealthy and organized societies, were much weaker than the vast civilizations of the alluvial lowlands. </span>
