As a kid, I only knew of three seasons in India – Summer, Rainy (Monsoon), and Winter. When I moved to the USA, I learnt about two more – Fall and Spring. Did someone say, Autumn?
Delhi Tourism website lists five seasons – Winter, Spring, Autumn, Monsoon, Summer. Makes me wonder – did I miss some science class in school or something? If you have lived in India, what kind of seasons have you heard of?
Anyway, don’t you think these seasons a kind of awakening? Endotherms or warm-blooded animals that generate body heat tend to slow down during winter. Their metabolism, energy consumption, and growth slows down. It’s nature’s way of conserving energy. Even seeds stay dormant until the right environmental conditions favour its growth.
After a period of this deep-sleep or sometimes called as hibernation, these species are awakened by the sun’s warmth. Spring sunshine wakes them up.
When the rain falls, you smell the strong scent (petrichor) in the air after a dry spell produced by awakened bacteria.
External temperatures affect dormancy. Global warming is changing these amazing phenomena – causing spring to arrive early and autumn to come late. Sadly, some species are finding it hard to adapt. The world needs to wake up to this.
