Guili to Liyue distance = 100 km/140.6 px
0.7 km/px
a = 297.92 km
b = 258.09 km
Elipse area = pi*a*b = 2.42×10^5 km2
Volume of Mondstadt = 2.42×10^5 km2 * 3km = 726000 km3
7.26e+14 m3 * 1.112kg/m3 = 8.07312e+14 kg
(Area of country in m^2 * (8000m or 11800m)) * 1.003 * CAPE
2.42 × 10^11m2*8000m*1.003*4000j/kg = 7.767232e+18 Joules
Blizzards are usually −12 °C, with the temperature change being 20.5 Kelvin. According to the Snowstorm calc blog
Specifc heat capacity is 1000
We already calculated the mass
8.07312e+14*1000*20.5 = 1.6549896e+19 Joules
Total = 2.4317128e+19 Joules = 5.8 Gigatons, Island level
