Abstract

Among the earth's climate changes, cyclone formation and its associated atmospheric turbulences are the most severe atmospheric phenomena. Although modern meteorological science has made significant advancements in predicting atmospheric events and monsoons, India's ancient astro-meteorology principles possess highly detailed, empirical, and deep observational rules. This paper comparatively analyzes scientific factors—such as ocean thermal energy changes and the Coriolis force—alongside astrological concepts like planetary conjunctions and retrograde motion.

Specifically, this study compares the cloud gestation period (Garbhalaksana - the 195-day rule), the classification of four types of clouds (Avartaka, Samvartaka, Pushkara, and Drona), planetary conflicts known as 'Graha Yuddha', and ancient rainfall measurement techniques, as described in the 6th-century CE text "Brihat Samhita" authored by Varahamihira, with modern scientific data. Furthermore, this paper provides a detailed analysis of the statistical evaluations, drought indices (DPI and DM) developed by the ancient Indian hydrology and meteorology researcher R. N. Iyengar, and the predictive accuracy of modern Machine Learning models (Random Forest, Support Vector Machine, Linear Regression) that incorporate Varahamihira's theories.
