Mushtari ka Azeem Surkh Dhaba 200 saal se kam purana ho sakta hai
Mushtari ki dastkhaati khasoosiyat iska Azeem Surkh Dhaba ho sakta hai ke teen sadiyon se zyada pehlay dehaikal sayare par dekha gaya wahi siyah dhaba na ho.
1665 se 1713 tak, maahir-e-falakiat Giovanni Domenico Cassini aur doosron ne Mushtari par aik siyah bayza shakal ka mushahida kiya jise permanent spot ka naam diya gaya. Ussi arz balad par Mushtari par jahan ab Azeem Surkh Dhaba ghoom raha hai. Muhaqiqeen ne aaj hairat ka izhar kiya hai ke kya yeh dhabay aik jaisay hain?
Taqreeban 360 saal par mushtamil Mushtari ke khakay aur tasaveer ka tajziya batata hai ke dhabay alag alag hain, muhaqiqeen ne 28 June ko Geophysical Research Letters mein report kiya. Isi mutaale se computer ke naqool bhi Azeem Red Spot ki asal surat ki taraf ishara karte hain, jisse zahir hota hai ke mukhalif jet streams ke darmiyan hawa mein khalal ne sayare ke dehaikal, surkh toofan ko kickstart kar diya hai.
Azeem Surkh Dhaba hamaray nizaam-e-shamsi ka sab se bara bhanwar hai. Mushtari ke junubi nisf kora mein waqiya, aandhi ke jhonke 600 kilometer per ghanta se zyada hain. Magar yeh wazeh nahi hai ke yeh jagah kitni peechay jati hai aur ise kis cheez ne ghoomaya.
Khush qismati se, mazi ke kuch sayaraat ke mushaahideen ne apni dureebino ke zariye jo kuch dekha uska khaka banaya. “Purane maqalaat aur kitabon mein in mushahidaat aur drawings ki tafseel dekhna bohat purjosh tha jo falakiat daano’n ne bari durusti ke sath banai thi,” Agustin Sánchez-Lavega, Bilbao, Spain mein University of the Basque Country ke maahir-e-falakiat aur sayaraati science daan kehte hain.
Sánchez-Lavega aur uske saathiyon ne maqamat par record khood dala. 1713 se shuru hone wale, Mushtari ki ittilaon mein permanent spot ki koi alamat nahi milti. Phir, 1831 aur is ke baad ke dahiyaon mein, drawings mein Azeem Surkh Dhaba se mushabihat rakhtay hue aik jagah dikhai deti hai – aik wazeh bayza jo surkh rang ka ho gaya tha.
Drawings se permanent spot ki paimish batati hai ke yeh 1879 mein li gayi Azeem Red Spot ki tarah taqreeban aik tahai se deyrh chauraai thi, jo us waqt Zameen ki chauraai se teen gunah zyada thi. Muhaqiqeen ne natija akhaz kiya ke 118 saalon ke record mein permanent spot ki adam mojoodgi aur is ke chhote size se pata chalta hai ke yeh Azeem Red Spot ke ubarne se pehlay hi ghayab ho gaya tha.
Kentucky mein University of Louisville ke sayaraati science daan Timothy Dowling kehte hain, “Yeh bohat qabil-e-qabool hai, aur unhone waqai aik acha kaam kiya hai.
Magar yeh abhi tak wazeh nahi hai ke Mushtari ka mashhoor toofan kaise aaya. Sánchez-Lavega ki team ne teen imkanaat ki chhaan been ke liye Mushtari ke mahaul ke computer simulations ko chalaya: ghoomte hue ilaqon ka inzimam, aik bara toofan ke nateejay mein ya muqalif jet streams ke darmiyan khalal.
Ibtidai Azeem Surkh Dhaba ke size ko paida karne ke liye bhanwaron ko mazboot karne ki zarurat hoti hai jo khud itnay baray hotay hain jitna ke Red Spot us waqt tha. Team ki report ke mutabiq is ka imkaan nahi hai, kyun ke is tarah ki khasoosiyat dekhi gayi hoti. Dar-e-meean, aik bari garaj chamak ke simulations ibtidai Azeem Red Spot ki tarah bara maqam paida karne mein naakaam rahe.
Magar gardish ka aik ilaqa is arz balad par maghrib ki taraf harkat karne wale aik jet nadi aur aik mashriq ki taraf barhney walay ke darmiyan ban sakta tha. Dabao ki kharabi ki wajah se hawa apne saron par U-turn le sakti hai, jisse aik aisa bahao paida ho sakta hai jo aik saray par shumal se junub aur doosray saray par junub se shumal ki taraf more ga. Sánchez-Lavega kehte hain ke yeh ghoomnay wala khitta Azeem Red Spot ke peish khima ke tor par kaam kar sakta tha.
Dowling kehte hain ke magar baray aandhi ke toofan ki tashkeel ka mutaala karne ke liye istemaal kiye jane walay naqool mein garaj chamak ki sar-garmi shaamil nahi hai, jo is baat ke liye ahem hai ke Azeem Red Spot khud ko kaise barqarar rakhta hai. Woh kehte hain ke is arz balad par kurah-e-ard ke gird garaj chamak ke toofanon ka aik halqa banta hai aur aakhir kar yeh toofan Great Red Spot mein shaamil ho jate hain – aur buniyadi tor par khana khilate hain. Great Red Spot in toofanon ko beejne mein madad kar sakta hai. Yeh itna bara hai ke yeh is arz balad par kurah-e-ard ke gird gas ke bahao ko roakta hai, jisse garaj chamak ke liye tayar hone wala kam dabao wala ilaqa banta hai. “Yeh aik aalami nizaam mein hai.”
Azeem Surkh Dhaba 1800 ki dehai mein nazar aane ke baad se sukarta ja raha hai. Yeh fi hal zameen se 1.1 guna chowra hai. Taweel gumshuda permanent spot ke size ke barabar. Dowling kehte hain ke yeh us spot ki qismat ka hissah ban sakta hai. Aik sukrta hua maqam apne aap ko barqarar rakhne ke liye itni garaj chamak ki sar-garmi ko eindhan nahi de sakta hai. “Kuch log hain jo abhi zinda hain. Kuch chhotay bachay jo iska anjaam dekh sakte hain.
