			=== 18th of January ===
			The entire exam was open book - you could bring everything.

			Theory part - open book (1.5hr)

			# Evolution of cloud droplets
			## Draw the evolution of a cloud droplet's radius after formation on the graph to the right (x-axis = radius, y-axis = height above cloud base)
			## What mechanisms contribute to the growth of cloud droplets? Explain them and indicate where on the graph they are of importance.
			## ..?

			## What is the physical meaning of the last term? Why does this contribute to changes in surface pressure?
			# Paper: in one paper, the probabilistic outcomes of different models are evaluated based on an error metric specifically designed for this purpose.
			## Which paper and which graph am I talking about?
			## Explain how the considered models work.
			## Which models underperform and why?

			Exercise part - remaining time

			# Given a map with isopleths (constant geopotential height) and isotherms for the 500 hPa level.
			## Is there warm or cold air advection at point A? Explain.
			## Estimate the magnitude of the geostrophic wind at point A.
			## Calculate the thermal wind at point A. You can leave the coriolis parameter as is.
			# ? forgot
			# A droplet is suspended in a cloud chamber with initial drop radius 10^-8m, vapour pressure of 23 hPa, pressure of 1000 hPa, temperature of 20 degrees Celsius, diffusion coefficient of 10^2 m^2/s and an supersaturation of 4%.
			## If you leave the droplet for one minute, what size will it be?
