05 May Dancing with Monsoon
Forecast of annual monsoon rains. It is remarkable that ancient Hindus acquired this accurate knowledge without the aid of modern instruments.
Since crop production depended almost entirely on seasonal monsoon rains, it was imperative that methods of predicting rainfall were developed. Indian knowledge base in mathematics and astronomy was strong.
Krishi-Parashara and Brhat Samhita give, what today one could describe as, simple astrological models for predicting rains in a particular season.
Parashara’s main technique of forecasting rain was based on the positions of the Moon and the Sun in the sky.
Varahamihira in his Brhat-Samhita considered lunar mansions in predicting seasonal rainfall. It is noteworthy that even today a large number of farmers in India, carry out farm operations based on the local variations of these old models.
Kautilya in Artha-sastra indicates primitive models for optimum rainfall for most crops. It is significant that the great poet, Kalidasa in his immortal poem, Meghdoot, described the course of monsoon clouds from the Bay of Bengal through central and northern Indian plains to the Himalayas.
Life in Ancient India depends on the different climates. India’s climate varies depending on the season. There are three main seasons: hot and dry, hot and wet, and cool and dry. The average temperature is about 74 Fahrenheit.
‘Vedic Rainfall prediction’ is an art of predicting the time and amount of rainfall expected in thecoming year, by observing some signs from living and apparently non-living things in the nature.
Vedic scriptures describe that just as a mother conceives a child, Mother Nature also conceives Rain.
