When nature rains supreme

The monsoon is the greatest show on

Earth

, the confluence of multiple mind-boggling scientific factors. India’s southwest monsoon is caused by a low-pressure heat zone developing in the eastern

Himalayan

foothills. India’s landmass has a unique shape which traps this heat and intensifies it — meanwhile, the temperature over the southern Indian Ocean starts to cool.



Nature abhors a vacuum and so, winds, rich in moisture from these seas, start blowing towards the low-pressure heat zone. As these winds travel across India’s gradients, they rise. The gain in altitude causes a drop in temperature, driving condensation — and rain. The early monsoonal airstream in the Western Ghats, for instance, pushes at the mountainous heights, propelling thicker clouds upwards, windward slopes thus receiving upto 200 inches of rain.



The antiquity of India’s monsoon is unique. Scientists have found the Indian monsoon began strengthening fifty million years ago when the

Tibetan Plateau

arose. Three million years ago, in the icy Pleistocene, as the

Pacific Ocean

froze, the Indian Ocean grew warmer, further intensifying the monsoon through time. Until now, this monsoon has been a rejuvenating force, generating crops, refreshing rivers and enabling biodiversity. Fruit and flowers blossom in the rain, frogs sing, birds call and mushrooms emerge in mossy forests and drenched fields.

This beautiful tapestry of life embraces us human beings, whose gratitude for the rain has found expression in paintings, poetry and song. However, this mighty meteorological entity is now profoundly impacted by human-caused global warming. As Co2 levels rise and marine atmospheres dry, these air currents are growing increasingly volatile.



Yet, as Times Evoke’s global experts emphasise, the answers are blowing in the monsoon wind. We must carefully conserve the water these rains bring and sustainably design our habitations, facilitating and not impeding these downpours. Alongside, we need a judicious use of fossil fuels to preserve the rain’s natural rhythms. Join Times Evoke on a vibrant journey exploring the monsoon — nature’s amazing gift that truly renews us.
