Varahamihira describes the Rahu (shadow planet) model for eclipses. While today we know eclipses are caused by the Moon’s node, his computational algorithm for the duration and magnitude of a solar eclipse was tested against known eclipses from 500–600 CE. The Brhat Samhita’s formulas predict eclipse timings within a 15–20 minute margin of error – remarkable for naked-eye astronomy.
The Brhat Samhita states: “When ants carry eggs, when the crow bathes in dust, and when the rainbow appears in the west—rain is imminent within 48 hours.” Biometeorologists have verified these biological indicators. Ants move eggs to higher ground (rising humidity). Crows dust-bathe to remove parasites before rain increases humidity. This is not superstition; it is phenology—the study of periodic biological phenomena. The verification accuracy stands at 85% for short-term forecasts. Many of these methods align with modern hydrological
