Utqiagvik, Alaska jo America ka northernmost settlement hai ne is saal ka aakhri sunrise dekh liya hai. Ab ye sheher 22 January 2026 tak suraj ko nahi dekhega, kyunki Arctic Circle mein Polar Night ka daur shuru ho gaya hai.
Polar Night Kya Hai?
Polar Night ek aisa phenomenon hai jahan Suraj horizon ke upar nahi uthta aur din ke roshan hone ka waqt nahi hota. Utqiagvik mein agle 64 din tak direct sunlight nahi hogi. Lekin complete darkness nahi hogi; sheher mein civil twilight ka experience hoga yeh woh pale blue light hai jo normally dawn ke pehle dekhi jaati hai.
Sheher Ki Location aur Population
Utqiagvik, pehle Barrow ke naam se jaana jaata tha, Fairbanks se lagbhag 500 miles northwest mein hai. Yahan ki population takriban 4,400 logon ki hai, aur sheher mein archaeological sites bhi maujood hain jo 500 CE tak wapas jati hain.
Mausam aur Temperature
Sunlight aur daytime heating na hone ki wajah se, Polar Night ke dauran temperatures kaafi gir jaate hain. Ye extreme cold Arctic Circle ke liye typical hai aur is phenomenon ka asar Polar Vortex ki formation par bhi padta hai. Polar Vortex, stratosphere ke upar ek aisi cold air ki layer hai jo kabhi-kabhi neeche gir kar Lower 48 states tak bhi move kar sakti hai.
Earth Ki Tilt Ka Asar
Northern Hemisphere ka tilt, September se March equinox ke darmiyan suraj se door ho jata hai, jiske wajah se Utqiagvik aur baaki far-northern latitudes mein din ki roshni dhire-dhire fade ho jati hai aur December solstice ke around apni extremity par pohanchti hai.
Summary Point
Utqiagvik ke log agle 64 din tak suraj ko nahi dekhenge, lekin halka twilight ka experience zaroor hoga. Ye phenomenon sirf natural curiosity ka sabab nahi hai, balki Arctic ke extreme weather patterns aur global cold air flows ka bhi ek hissa hai.
