Transcribed Image Text:
Compute and plot the 30-minute average Reynold's stresses (u'w', v'w', u'v) and heat stress (u't', w't) for the entire dataset. The x-axis must be time, and the y-axis must be the stresses. For each stress, plot all five levels on the same figure. Make sure to label the axes with units, and the figure must include a legend. Discuss your results. Question 2: Compute and plot the turbulent kinetic energy and friction velocity ((u'w2 +v'w20.25) for all five levels. Determine which levels experience high values and explain why. Question 3: Find the Monin-Obukhov length for every 30-minute period and then compute z/L for all five heights. Determine which level experiences the highest and lowest stabilities. Question 4: Compute the 30-minute averaged sensible heat flux for every level and plot them on the same graph. Which levels experience the highest and lowest heat flux and why? Question 5: Use the z/L value from the 3rd level from the ground as a reference. Find the periods when the stability in the level was greater than 0.1. For those periods, plot the u'w', w't' for all levels. Repeat the same when the stability is less the 0.5. Discuss your results. function [average, prime] = detrend (input) s = 1; average = zeros (96, 1); for i=1:18000:1728000 average(s) = mean (input(i:i+17999), 'omitnan'); prime (i:i+17999) = input (i:i+17999) - average(s); S = s + 1; end end %Prime Average Function function [prime_average] = prime_average (input) j = 1; prime_average = zeros (96, 1); for i=1:18000:1728000 end end prime_average (j) = mean (input (1:1+17999), 'omitnan'); j = j + 1; Compute and plot the 30-minute average Reynold's stresses (u'w', v'w', u'v) and heat stress (u't', w't) for the entire dataset.
