Monsoon moves west, clouds of new crisis deepening...?
The climate of the entire indian subcontinent is primarily monsoon based, and its deep imprint is historically visible on every aspect of civilization and culture. The monsoon is a nexus of land-sky-sea, which in summer pours a huge amount of water vapor from the arabian sea and the Bay of bengal from Arakan to Kirthar Mountains and down from the himalayas to the vast river plains and the entire peninsular region and this water not only fulfills the water needs of the ecosystem till the next summer but has been determining the shape of the land and the geography of the humans living here for millions of years.
Where did the word monsoon come from?
Monsoon - whose name comes from the Arabic word mausim, meaning season - is a periodic change in the direction of the wind. Usually, between june and September, the indian subcontinent receives heavy rainfall during the southwest monsoon, which is caused by moist winds blowing from the oceans in the southwest. During the retreating northeast monsoon from october to December, the winds blowing from the northeast return with sufficient moisture from the Bay of bengal and promote rainfall in South India. Thus, the spread of the monsoon is never the same over the entire indian continent, its spread keeps changing according to place and time and this is its trend.
Historically, there have been major changes in the monsoon from time to time, the effect of which is clearly visible from the Indus Valley to modern times. But in the present era, the trend of the monsoon seems to be changing, at least in view of the change in the rainfall pattern in the last few decades. According to a 2022 study, about 83% of the total natural disasters are the result of extreme weather conditions, which are mainly related to heavy rains and floods.
