Passing throught the hot plasma of 3000-4000 deg F, they become vaporized droplets of 1u as indicated by ',' (US Weather Bureau symbol for drizzle), and coalesce above the plasma in the inner core of the cloud or inner invisible stem until the upper 1/4 portion of the cap flares out. This is the volume where the coalescing occurs as indicated by double droplets ("). Where the divergence starts, we have little or no more coalescing indicated by (%). The final coalesced larger droplets have been pushed along and settle at the bottom third of the cap indicated by (o).
