15 December Se Karachi Mein Sardi Ki Shiddat Mein Izafa
Karachi mein mausam aik naya rukh ikhtiyar karne ja raha hai jahan shehar mein 15 December ke baad sardi ki shiddat mein izafa expected hai. Pakistan Meteorological Department (PMD) ke mutabiq din ke waqt mausam zyada tar khushk rahega, jabke raat aur subah ke auqat mein thand zyada mehsoos ki jaegi.
Subah Ka Mausam: Zyada Nami Aur Halki Dhund
Shehar ne jumma ke din subah 93% humidity ke sath aankh kholi, jis ki wajah se fiza mein halki dhund aur haze dekhi gayi. Zyada nami ke bawajood barish ka koi imkaan nahi hai aur din bhar mausam khushk rehne ka andesha hai.
Aaj Ka Darja-e-Hararat Aur Hawaon Ki Surat-e-Haal
PMD ke mutabiq Karachi ka zyada se zyada darja-e-hararat taqreeban 31 degree Celsius tak ja sakta hai. Shehar mein mashriqi shumali hawaein chal rahi hain jin ki raftaar qareeban 9 kilometer per hour record ki gayi hai. Din ke waqt dhoop aur raat ko thandi hawaon ki wajah se temperature mein wazeh farq mehsoos hoga.
15 December Ke Baad Sardi Kyun Barhegi?
Climate change expert Dr Zainab Naeem ke mutabiq maujooda khushk sardi ka talluq La Nina weather pattern se hai. Unhon ne wazeh kiya ke La Nina ke dauran sardiyon mein South Asia tak kam badal pohanchte hain, jis ki wajah se barish kam aur mausam zyada khushk rehta hai.
Barish Mein Kami Aur Sardiyon Ka Mukhtasir Hona
Dr Zainab ka kehna hai ke pichlay kuch saalon mein October se December tak barishon mein numaya kami dekhi gayi hai. Jo sardi pehle zyada arsey tak rehti thi, ab woh mukhtasir ho chuki hai. Climate change ne is trend ko aur tez kar diya hai, jis ka asar zaraat aur pani ke zakhair par bhi par raha hai.
Din Garam, Raat Zyada Thandi Kyun?
Experts ke mutabiq jab hawa khushk hoti hai to din ke waqt zameen zyada tezi se garmi jazb karti hai, jis se din ka temperature barh jata hai. Jabke raat ke waqt wahi garmi tezi se zaya ho jati hai, jis se thand mein izafa hota hai. Isi wajah se Karachi mein din aur raat ke temperature mein farq barhta ja raha hai.
Aane Wale Din: Halki Barish Aur Thand Ka Arzi Asar
Mahireen ka kehna hai ke mid-December ke baad sirf halki barish ka imkaan hai, jo normal se kam hogi. Agar barish hoti bhi hai to thand kuch arsey ke liye barhegi, lekin yeh asar zyada dair paida rehne wala nahi hoga.
Climate Change Aur Mustaqbil Ke Challenges
Dr Zainab Naeem ne tanbeeh ki ke Pakistan climate change ke asraat pehle hi mehsoos kar raha hai, jismein shehri aur dehati ilaakon mein flooding shamil hai. Unhon ne kaha ke science aur policy ke darmiyan behtar rabta zaroori hai taake mustaqbil ke khatrat, khas taur par 2026 mein expected flooding, ka muqabla kiya ja sake.
Karachi Walon Ke Liye Mashwara
Mahireen mashwara dete hain ke shehri thand se bachao ke liye raat ke waqt garam kapron ka istemal karein, jabke din ke waqt pani zyada peena aur khushk mausam ka khayal rakhna zaroori hai. Sardi ka yeh phase dheere dheere barhega, is liye ehtiyaat pehle se hi behtar hai.
