As expected, thermistors 2 and 3 consistently reported the greatest temperature, while probe five, the deepest, was by far the coolest. This is clearly indicative of the expected behaviors of the Hadley cell. Also noteworthy in the above plot are several "milestones" in the experiment. Since the thermistors were inserted prior to anything else was set up, they recorded the rise in temperature when the water (slightly above room temperature) was added, the insertion of ice into the central container, and the "mixing" of the fluid when the tank was set about rotating.
However, in addition to confirming the existence of the Hadley cell in this experiment by means of temperature data, we can investigate the "winds" within the fluid using vertically-dropped permanganate. Figure 1.6 depicts a composite frame of permanganate patterns ten seconds apart, while Figure 1.7 shows a Geogebra photogrammetric analysis of the composite photograph. In Geogrebra, the photograph was scaled so that the axes supplied are in meters. In addition, the yellow line in the latter figure contours the first "snapshot" of permanganate shading, with the blue line marking its position some ten seconds later.

From Figure 1.7 the horizontal distance traveled by the fluid as a function of height may be obtained, allowing one to deduce the translational velocity at different levels throughout the fluid. Figure 1.8 shows this analysis:
