Bhaarat ki jalavaayu

Daytime view of an almost lifeless expanse, dry rocks and sand marked only by the odd lone shrub. The dry terrain reaches to a chain of mountains in the far distance, near the horizon. A bank of clouds soars above the void, but it does not appear to hold the promise of rain. A far darker, larger, more turgid cloud bank sits above the distant mountains, above the horizon.
uttaraakhand mein foolon ki ghaati yahaaain pavanonmukh dhaal hone ki vajah se paryaapt varsha hoti hai
tirunelaveli ke sameep ek ardhashushk kshetr; yeh kshetr vrushtichhaaya kshetr hai jabki iske pashchim mein kuchh hi kilometer ki doori par Kerala mein pavanonmukh dhaalon par khoob hariyaali paayi jaati hai

Bhaarat ki jalavaayu mein kaafi kshetreeya vividhta paayi jaati hai aur jalavaayaveeya tatvon ke vitran par Bhaarat ki kark rekha par avasthiti aur yahaaain ke sthalaroopon ka spasht prabhaav drushtigochar hota hai. ismein himaalaya parvat aur iske uttar mein Tibet ke pathaar ki sthiti, thaar ka marusthal aur Bhaarat ki hind mahaasaagar ke uttari sheersh par avasthiti mahatvapoorn hain. himaalaya shreniyaaain aur hindukush milkar Bhaarat aur Pakistan ke kshetron ki uttar se aane waali thandi kataabaitik pavanon se raksha karte hain. yahi kaaran hai ki in kshetron mein kark rekha ke uttar sthit bhaagon tak ushnakatibandheeya jalavaayu ka vistaar paaya jaata hai. thaar ka marusthal greeshm ritu mein tapt ho kar ek nimn vaayudaab kendra banaata hai jo dakshin pashchimi maanasooni havaaon ko aakrusht karta hai aur jisse poore Bhaarat mein varsha hoti hai.

kopen ke vargeekaran ka anusaran karne par Bhaarat mein chhah jalavaayu pradesh parilkshit hote hain. lekin yahaaain yeh avashya dhyaan rakhana chaahiye ki ye pradesh bhi saamaanyeekaran hi hain aur chhote aur sthaaneeya star par uchchaavach ka prabhaav kaafi bhinn sthaaneeya jalavaayu ki rachana kar sakta hai.

bhaarateeya jalavaayu mein varsh mein chaar ritueain hoti hain: jaada, garmi, barasaat aur sharadakaal. taapamaan ke vitran me bhi paryaapt vividhta dekhne ko milti hai. samudra tateeya bhaagon mein taapamaan mein varsh bhar samaanata rahati hai lekin uttari maidaanon aur thaar ke marusthal mein taapamaan ki vaarshik range kaafi jyaada hoti hai. varsha pashchimi ghaat ke pashchimi tat par aur poorvottar ki pahaadiyon mein sarvaadhik hoti hai. poorvottar mein hi mausinraam vishv ka sabse adhik vaarshik varsha wala sthaan hai. poorab se pashchim ki or kramash: varsha ki maatra ghatati jaati hai aur thaar ke marusthaleeya bhaag mein kaafi kam varsha darj ki jaati hai.

bhaarateeya paryaavaran aur yahaaain ki mruda, vanaspati tatha maanaveeya jeevan par jalavaayu ka spasht prabhaav hai. haal mein vaishvik taapan aur tajjanit jalavaayu parivartan ke prabhaavon ki bhi charcha mahatvapoorn ho chali hai.[1][2][3]

"India Average Temperature Map": A map of India overlaid with five zones. A violet zone, with ambient temperatures averaging less than 20.0 degrees Celsius, envelops Himalayan and trans-Himalayan India, as well as the Khasi Hills on the Meghalaya Plateau. A transitionary blue zone of between 20.0 and 22.5 degrees, lies just south of the violet areas; another blue area lies in the extreme southwest of the country, focused on the high Western Ghats. Two contiguous green areas (averaging 22.5 to 25.0 degrees) envelop the blue regions, with the northern one snaking into the Vindhya Range of central India. The remaining yellow and red areas, designating average temperatures above 25.0 degrees Celsius, constitute by far the greater part of the country.
