The product of the FD magnitude and duration vs. products of different solar wind parameters. a) magnetic field enhancement and disturbance duration, Bt_B; b) magnetic field fluctuations and disturbance duration, δBt_B; c) magnetic field enhancement, speed and disturbance duration, Bv_maxt_B; d) magnetic field enhancement and speed, Bv_max. The data is taken from the measurement I data set. |FD|t_FD is expressed as %  ×  h, Bt_B and δBt_B are given in nT  ×  h, Bv_maxt_B in nT  ×    km   s^-1    ×  h and Bv_max in nT  ×    km   s^-1.
