Barish yaani ki rain prakritik ghatna hai jo hoti hai jab pani ka bukhar tatah tak jaata hai aur bundon ki roop mein dharti ke tatah par gir jaata hai. Yeh hamare prithvi ke pani ka chakra ka mahatvapoorn ang hai aur hamari duniya par jeevan ko banaye rakhne mein mahatvapoorn bhumika nibhata hai. Is lekh mein hum barish ke piche ka vigyaan aur yeh kaise banti hai uski jaankari prapt karenge.
Barish kaise banti hai, iska vigyaan samajhne ke liye, hum pehle pani ka chakra ko samajhna zaruri hai. Pani ka chakra ek aisa prakriya hai jahan pani dharti ke tatah se uday hota hai aur hava mein chala jaata hai. Pani ka bukhar badalta rehta hai aur badalte huye tatah mein pahunchta hai. Jab pani ka bukhar baadal ban jaata hai aur baadal saturate ho jaata hai, toh yeh baadal apne pani ko bundon ki roop mein, jaise ki barish, baarish, barf, sleet ya hail ke roop mein jama kar dete hain.
Barish ke kai tarike hote hain, lekin sabse aam tareeka nimantran hai. Nimantran tab hota hai jab baadal ki pani ki bundein itni badi ho jaati hain ki hawa ke current ke khilaaf khade ho jaate hain aur dharti par girne lagte hain. Baadal ke pani ki bundon ke badhne ka tareeka ek vishaal prakriya hai jismein temperature, dabav aur namakaran jaise kai karak hote hain.
Baadal mein pani ki bundon ke badhne ko prabhavit karne wala mukhya karak temperature hai. Hava jo dharti ke upar chadhti hai, thandi hoti hai aur thandi hone par ismein zyada pani ka bukhar nahi rehta hai. Jab hava saturate ho jaati hai, toh adhik pani ka bukhar baadal ki roop mein jama ho jaata hai.
Baadal mein pani ki bundon ke badhne ko prabhavit karne wala ek aur karak dabav hai. Hava jo dharti ke upar chadhti hai, phailti hai aur thandi hone se badi ho jaati hai, isse pani ki bundein badhne lagti hain. Jitni badi bunden, utni tezi se girne lagti hain.
Namakaran bhi baarish ke nirman mein mahatvapoorn hai. Namakaran matlab hawa mein namak ka asthan hai. Jab hava namak ke saath bhari hoti hai, toh aur jyada namakaran hota hai. Yeh matlab hai ki namakaran ke kshetron mein baadal jyada tar barish karte hain.
Jab baadal ki bundein itni badi ho jaati hain ki dharti par girne lagti hain, toh unki girti hui sthiti mein hawa ka pratirodh pani kibundon ke oopar kaam karta hai aur bunden dharti par girne lagti hain. Jab bunden dharti par girne lagti hain, toh unki tez gati aur mausam ki shuruwat se pehle dharti ke tatah ko geela karne mein madad karti hain. Isse duniya mein nayi jeev-jantu ki utpatti hoti hai aur paudhe, ped aur anya prakruti ke jeev amulya poshan prapt karte hain.
Barish ke piche ek aur bada karak hai - yeh hai sanskritik mausam. Sanskritik mausam dharti ke parvat-shreniyon aur dhalanon se prabhavit hota hai. Mausam ki parivartan ke samay parvat-shreniyon se tapmaan mein badlav hota hai, jisse pani ki bundon ki nirman ki prakriya par asar padta hai.
Jaise hi sanskritik mausam badalta hai, baadal ka aakar bhi badal jaata hai. Mausam ke anusaar, baadal ke prakar bhi badalte rehte hain. Jab mausam garm hota hai, toh baadal jaldi nirmit hote hain aur barish jyada tez hoti hai. Jab mausam thanda hota hai, toh baadal dhire-dhire nirmit hote hain aur barish dheemi hoti hai.
Barish ka shuruat kaise hoti hai, yeh bhi sanskritik mausam par nirbhar karta hai. Jaise hi mausam badalta hai, baadal bhi apni prakriya shuru karte hain. Pehle baadal mein chote-chote bunde banti hain, jo dhire-dhire badhkar bade baadal ke roop mein parivartit hote hain. Jab baadal ki bundein itni badi ho jaati hain ki hawa unke khilaaf ho jaati hai, toh unki girne ki prakriya shuru ho jaati hai.
Barish ka mausam bhi ek dusre se alag alag ho sakta hai. Kabhi kabhi barish tez hoti hai, toh kabhi kabhi barish ka pata hi nahi chalta hai. Yeh sab mausam ke anusaar hota hai. Mausam ke sath-sath barish ki matra aur gati bhi badalti rehti hai.
Isliye, hamari prakriti ki is sundar ghatna ko samajhna bahut zaruri hai. Barish ke nirman ki prakriya mein duniya ke kai karak hote hain, jinhe samajhne ke baad hum duniya ki prakriti aur mausam ko behtar tarike se samajh sakte hain. Iske alava, hum iske mahatv ko bhi samajh sakte hain. Barish ke bina, hamari duniya bilkul adhoori hoti hai aur prakriti ke jeev jantu ke liye avashyak poshan bhi nahi milta hai
