Distributions of normalised daily means of near-Earth solar wind parameters for the near-continuous interplanetary data for 1996–2016 (inclusive) for: (a). the solar wind speed, V_sw/<V_sw>_τ = 1yr; (b). the square of the solar wind, V_sw²/<V_sw²>_{τ = 1 yr}; (c). the solar wind number density, N_sw/<N_sw>_{τ = 1 yr}; (d). the solar wind kinetic energy density, N_swV_sw²/<N_sw V_sw²>_{τ = 1 yr} (the other terms cancel on normalisation if the mean ion mass is assumed constant); (e). the interplanetary magnetic field strength, B/<B>_{τ = 1 yr}; and (f). the power input into the magnetosphere, Pα/<Pα>_τ =1 yr. In each case the blue histogram gives the occurrence in bins 0.1 wide and the mauve line is the best-fit lognormal distribution, which has a mean of m = 1 and a variance v, the best-fit value of which is given in each case.
