1.3 مليار فولت في سحابة.. جسيمات كونية تكشف أسرار العواصف الرعدية

ملخص الخبر

  • كشفت دراسة حديثة أن تفاوت رصد العواصف الرعدية في اتجاهات مختلفة يعود لتأثير المجال المغناطيسي للأرض على الجسيمات الكونية.
  • تستخدم هذه الجسيمات، المعروفة بالميونات، لقياس فروق الجهد الكهربائي الهائلة داخل السحب الرعدية دون الحاجة لإرسال أجهزة لقلبها.
  • أظهرت القياسات وجود جهد كهربائي يصل إلى 1.3 مليار فولت في إحدى العواصف، وهو رقم يتجاوز القياسات المباشرة بكثير.
  • أثبتت المحاكاة الحاسوبية أن اختلاف نسب الميونات الموجبة والسالبة في الشرق والغرب هو السبب وراء الانحياز في بيانات التلسكوب.

ملخص كتبه الذكاء الاصطناعي من نص الخبر في مصدره.

كشفت دراسة جديدة أن المجال المغناطيسي للأرض يفسر سبب رصد تلسكوب "جرابس-3" الهندي عواصف رعدية في الشرق أكثر منها في الغرب. وأظهرت المحاكاة أن مغناطيسية الأرض تغير نسب الميونات الموجبة والسالبة.
