Mausam kendra saare yantron ko ek saath laakar niyamit antaraal par paathyaank leta. Swachaalit Mausam Kendra (AWS) sensor se taapmaan, aardrata, hawa, baarish aur daab bina kisi ki maujoodgi ke darj karta; ek ab Sikkim ki hims-jheel par 4800 m se oopar khatarnaak mausam ki pehle chetaavni dene ko lagaa hai.
Mausam vaigyaanik lambe data ka adhyayan karke ghanton, dinon ya hafton aage ka mausam batate. Jalvaayu parivartan se zyaada baadh, sookha, lu aur chakravaat, to poorvaanumaan jaanein bachaate: machhuaron ko samudra na jaane ko kehte, aur chakravaat se pehle poore tat khaali karaaye jaate. IMD rang-code naksha jaari karta: peela = nazar (jaankaari rakho), naarangi = satark (taiyaar raho), laal = chetaavni (kadam uthaao).
Alag samay alag tatva haavi: July mein baarish, May aur December mein taapmaan, chakravaat aane par daab, aur jab uttar Bharat mein garam, dhool bhari loo chalti tab hawa. Mausam jalvaayu, lambe samay ke pattern, se gehra juda, jo hum aage padhenge.
