CONTRADICTIONS
A contradiction is examined in this paper where, despite conditions being unfavorable to the formation of clouds, heavy aircraft spray activity in the morning hours in Santa Fe, New Mexico resulted in the classic formation of extensive cirrus-, cirrostratus-, and cirrocumulus ‘appearing’ cloud decks at a relative humidity of 36%. Six reliable sources, including researchers at NASA and NOAA, and Vincent Shaefer (inventor of cloud seeding in 1946), affirm that cloud formation is not expected to even begin below relative humidities of 70%. And yet repeatedly since the early part of 1999 such formation of cirrus - cirro-stratus - and cirrocumulus cloud decks are observed forming as a direct result of aircraft activity in conditions of extreme low humidity in the southwest desert.
