Web16.1 Rayleigh Method. As early as 1899, Lord Rayleigh made an ingenious application of dimensional analysis to the problem of the effect of temperature on the viscosity of gas. Rayleigh’s method is outwardly different from Buckingham’s method; let us consider the drag force F that a smooth spherical body experiences in a stream of ... WebSep 28, 2005 · The drag is set to zero just above the tropopause at 17 km, has a timescale of 2.5 days near the stratopause, and decays linearly in time from 1965 to zero in 1995. This perturbation results in an upward trend of 8.5 ms −1 over the 1965–1995 period in the lower stratospheric zonal wind at 50 hPa and 60°N, in contrast to the almost constant …
