WebApr 10, 2024 · Taken at face value, the wet-get-wetter perspective would predict on average an increase in P − E, which one may interpret as a tendency toward overall moister conditions. The AI/SM phase space allows us to look beyond the time-mean picture (e.g., the 5 months warm-season considered here) and explore the redistribution of P − E on daily ... Webi.e. x(t) and p(t) satis es the classical equations of motion, as expected from Ehrenfest’s theorem. In summary, we have seen that the coherent states are minimal uncertainty wavepackets which remains minimal under time evolution. Furthermore, the time dependant expectation values of x and p sati es the classical equations of motion.
