Air of initial ML potential temperature 15C comes to rest over a 25C sea surface. Divergence is 10-7 s-1, and the initial /z = = 3.5 K km-1. Find and plot the warm airmass evolution of potential temperature and depth. Use Excel spread sheet calculation with time step of 360 s, and show 4000 iterations, and the plot of iterative solution and submit this as part of your solution. Your plot of the iterative solution should have time in days on the x-axis, zi (m) on the left y axis and (C) on the left y axis. The plot should show only the ML (C) and zi (m). Clearly indicate on the graph, the sfc (C) and the time that the new warm airmass has maximum thickness Estimate the time (you may create iterative solution using excel) that the new warm airmass has maximum thickness and compare this with the value obtained from the graph. Submit (EXCEL sheets) this with your answer.
