Still haven't been able to upload the images from a cell phone yet, for the odd wave patterns from near Shawnee, Oklahoma. Cold weather can be a 'science fiction' scene set of qualities at times. Very dense like storm clouds in warmer weather on Earth. If only we could see some of these heavy water vapor clouds at low level on Mars. I am sure the patterns on Mars are as fantastic as this denser atmosphere o Earth.
Possibly Fred hasn't recovered his original images for this topic as yet, Dave.
I presumed the Undulatus_asperatus type low level clouds were named long ago, but it is claimed the term is new and no reference to this type in history was explained. The type I was hoping to show are quite different, more regular, and as impressive but unique.
In Oklahoma we have nothing to equate to the Mt. Sharp 3 mile elevation rise which is influencing the cloud pattern Fred was describing. The reference to 'gravity wave' clouds was as close as I could guess as yet prior to seeing the rover images he described.
Nice ice storm across the entire US this week. Down to 0* F here in Oklahoma at times. Records were broken this week in locations.
