#2681 "Castellanus in the Wake of the CB"

#2681 "Castellanus in the Wake of the CB"
8x10 canvas oils

This is the view corresponding to #2680 "Singleton Morning Cumulonimbus" but looking out over the lake to the west at the weather that was approaching. There was a band of clear skies overhead but further to the west, skies were overcast. 

Water Vapour View at the time of the painting
The clouds on the leading edge were very convective castellanus. Further in the distance were gravity waves rippling on the warm frontal surface. I would guess that those gravity waves would fall into the "swell" category as the clouds were drifting fairly slowly toward the south with the winds in the atmospheric frame of reference. There were stronger westerly winds much further to the west that would be generating this ocean like swells that rippled the warm frontal surface - like a blanket on a clothes line shaken by a strong wind. 

The wedge of cool air was very shallow and identified mainly by moisture content. That frontal surface was eroded by noon and the temperatures and southerly winds both increased. 

This is the first in the sunrise series for Thursday June 16th, 2022 that include #2680 "Singleton Morning Cumulonimbus", #2681 "Castellanus in the Wake of the CB" and #2682 "Morning Anvils and Congestus". My painting #2663 "Singleton Calm After the Storm" deals with the image of the Derecho of May 21st, 2022.
