Evapotranspiration and precipitation prove the Earth is flat.

Calculation of the annual evapotranspiration of the Earth based on the Thornthwaite method.
The method uses this set of equations:
ETp = 16 × (10 × Tm ÷ I)^A
I = Σ (0,2 × Tm)^1,514
A = 0,49239 + (1,7912 × 10^-2 × I) - (7,71 × 10^-5 × I^2) + (6,75 × 10^-7 × I^3)
ETp = evapotranspiration.
I = annual heat index.
A = exponent calculated based on I.
I take into account that the average temperature of the Earth is ≈ 14º C.

4,75332226423 × 12 = 57,0398671708
I = 57,0398671708
A = 0,49239 + (1,7912 × 10^-2 × 57,0398671708) - (7,71 × 10^-5 × 57,0398671708^2) + (6,75 × 10^-7 × 57,0398671708^3)
A ≈ 1,3885
ETp = 16 × (10 × 14 ÷ 57,0398671708)^1,3885
ETp ≈ 57,64
Annual evapotranspiration:
ETp = 57,64 × 12
ETp = 691,68 millimeters
Evapotranspiration over the total area of the Earth:
ETp = 510100000 (Earth Area) × 691,68
ETp = 352825968 cubic meters
ETp = 352825,968 cubic kilometers
Here we have data on annual precipitation in all countries on Earth:

Precipitation = 185750
Precipitation = 185750 ÷ 195
Precipitation ≈ 952,56
Precipitation = 952,56 × 510100000
Precipitation = 485902948717 mm
Precipitation = 485902 km
In other words: the Earth's average annual precipitation (485902 km/510100000 km) is greater than the Earth's average annual evapotranspiration (352825,968 km/510100000). This means that there are unknown sources of atmospheric water, because in a closed system water needs to evapotranspire and then precipitate.
The unknown sources of atmospheric water are described in the Book of Enoch, they are chambers/portals through which hail, snow, frost, rain and dew proceed:
