Nature ke ishaare padhna
Instruments banne se bahut pehle log weather ka andaaza lagaate the. Jaanwaron aur paudhon ko dekhkar sanket milte the: bhaari baarish se pehle cheentiyon ka ande oonchi jagah le jaana, baarish paas ho to mendhakon ka zor se tarrana, panchhiyon ka neeche udna aur gilahriyon ka meve jama karna. Cheed ke shanku nam hawa mein beej bachaane ke liye band ho jaate hain aur sookhi hawa mein beej chhodne ke liye khul jaate hain. Ye gyaan ek peedhi se doosri tak pahuncha, aur India ke kai hisson mein log aaj bhi aise ishaare use karte hain, khaas kar monsoon kab aayega ye jaanne ke liye. Apne aas-paas ke bade-buzurgon se poocho ki wo kin ishaaron pe bharosa karte hain, aur apni bhaasha ki weather se judi kahaawatein likh lo.
Forecast kaise banta hai
Meteorology weather aur uske badlaav ka vyavasthit adhyayan hai, aur forecasting isi pe tiki hai. Meteorologists sirf aasmaan dekhkar andaaza nahi lagaate. Weather stations ke instruments temperature, baarish, pressure, hawa aur humidity naapte hain; readings tay samay pe li jaati hain aur kai saalon tak sambhaali jaati hain; aur vaigyanik is data ko padhkar andaaza lagaate hain ki agle kuch ghanton, dinon ya hafton mein weather kaisa rahega. Automated Weather Stations ab bahut si readings khud bhejte hain.
India Meteorological Department
India ki rashtriya weather seva, India Meteorological Department (IMD), 1875 mein bani. Iska motto, adityat jayate vrishti, ka matlab hai “suraj se baarish paida hoti hai”. Ye line Manusmriti se hai, jo aage kehti hai ki baarish se anaaj aur anaaj se jeev paida hote hain. Ye baat vigyaan se mel khaati hai: suraj ki garmi samudra, nadiyon aur zameen ka paani bhaap banaati hai, aur wahi bhaap baad mein baarish banke girti hai.
Warning map ke rang aur icons
IMD aise map jaari karta hai jinme har ilaake ko aane waale weather ki gambheerta ke hisaab se rang diya jaata hai, aur khatre ki kism ke icons lagaaye jaate hain: heat wave, cold wave, kohra, bhaari, bahut bhaari ya atyadhik bhaari baarish, bhaari barfbaari, ole, dhool bhari aandhi, bijli aur garaj, tez hawa, garam aur umas bhara mausam, aur bhi.
19 May 2024 ka map
Chapter mein 19 May 2024 ka IMD warning map hai. Do badi baatein dikhti hain. North-west aur north India mein heat wave thi: Punjab, Haryana ke saath Chandigarh aur Delhi, aur west Rajasthan laal the, aur east Rajasthan, Gujarat, Uttar Pradesh aur Bihar orange. South mein Kerala aur Tamil Nadu bhaari baarish, toofaan aur tez hawa ke liye laal the, jabki south interior Karnataka aur Assam aur Meghalaya bahut bhaari baarish ke liye alert pe the. Baaki lagbhag har jagah peela tha, zyaadatar bijli aur garaj ke liye, aur Konkan aur Goa aur Odisha ke tat garam aur umas bhare the. Us din koi ilaaka hara nahi tha, yaani India ke har hisse mein kuch na kuch nazar rakhne laayak tha.
Andaaze kyun zaroori hain
Sahi forecast kadam uthaane ka samay deta hai. Samudra mein toofaan ki sambhaavna ho to machhuaaron ko naav lekar na jaane ki chetaavni di jaati hai; cyclone aa raha ho to poora tatiya ilaaka khaali karaaya ja sakta hai; aur sthaaniya sarkaar aapda se pehle saadhan jama kar sakti hai. Kisaan buvaai aur katai ka samay tay karte hain, pilot aur naavik surakshit safar ki yojana banaate hain, aur parivaar kapde aur safar chunte hain. Climate change se sookha, baadh aur cyclone badh rahe hain, isliye ye andaaze aur bhi zaroori hain.
Ye kyun zaroori hai
Forecast tabhi kaam ka hai jab tum use padh sako. Har element ka matlab weather ke elements mein aur use naapne ka tareeka weather ke instruments mein seekho. Kitaab ke har sawaal ka jawab, 19 May 2024 ke map waale sawaalon samet, Chapter 2 ke NCERT solutions mein hai; poore Chapter 2 ke notes bhi dekho.
