This is a typical Thomson sketch from the spring of 1915. The wild cherries may be blossoming but this is most certainly a skyscape. The horizon is less than a quarter of the way up from the bottom. The clouds were the stars of this painting.
There are some things we know.
The clouds are altocumulus in the free atmosphere. All this means is that the clouds are above that boundary layer adjacent to the surface where friction and exchanges of heat and moisture with the earth play a big part in shaping the clouds. These clouds are all pretty uniform in shape and size and likely 6500 feet or more above the ground.
There are no gravity waves in the cloud deck so the wind is not strong but possibly deforming...
