Box plot of ENLIL-modeled solar wind ram pressure (P_ram, in nPa on the y-axis) over a ±5 day window centered on each outflow event (24 days), colored by mean ﹩{\mathrm{log}}_{10}(nv)﹩ in m⁻² s⁻¹. Open circles mark individual P_ram measurements that fall outside 1.5 times the interquartile range of the ±5 day window. A tentative positive correlation is visible between P_ram 4–6 days prior to detection and nv, most clearly during northern winter; the correlation weakens toward northern spring. Both quantities are binned in 24 hr intervals. No definitive interpretation is possible given ENLIL’s propagation uncertainty at 9 au (see Section 2).
