Video narration
Kya aapne socha hai, garam chai ki bhaap ki tarah, Bharat mein monsoon baarish kaise banata hai? Garmiyon mein Bharat ki zameen, khaaskar uttar aur madhya Bharat, Indian Ocean se tez garm hoti hai. Isse zameen ke upar low pressure, yaani kam dabaav, banta hai. Samudra par dabaav apekshakrit zyada rehta hai. Yahi pressure difference hawa ko samudra se Bharat ki or laata hai, aur vah apne saath nami laata hai. Ye South-West Monsoon winds do branches mein bantti hain: Arabian Sea Branch aur Bay of Bengal Branch. Nami wali hawa Western Ghats se takrakar upar uthti, thandi hoti aur jalvaashp ko boondon mein badal deti hai. Ise condensation kehte hain; phir baarish hoti hai. Himalayas in havaon ko uttar ki or nikalne se rokte hain. To jawaab hai: garm zameen se bana low pressure samudra ki nami-bhari hawa Bharat tak kheench laata hai, yahi monsoon rainfall banti hai.
