#2056 "Singleton Sunset Shades"

Sunsets never get dull or uninteresting at Singleton Lake. They offer 365 different paintings each and every year. The very rough panel ensures that I do not try to get too detailed. This was the view across Singleton Lake at 5:00 pm November 28th, 2017.

The elongated bands of cirrus were being stretched along deformation zones just east of the crest of the upper ridge. You can even imagine the swirls or vorticity centres required to construct these patterns.

You only need your right hand and fingers to understand the atmosphere. The so-called right hand rule instructs that you direct your right thumb in the direction of the flow and your fingers point the same way as the swirl or rotation. If the flow is going upward the flow is counter-clockwise if viewed downward from space. Look at the tip of your thumb to confirm this fact. Meteorologists call this cyclonic rotation and refer to the sense of rotation as a vorticity maximum. Air is going up.

If you point your right thumb down so that the air is descending, the rotation as viewed from space is clockwise. Look at the baby finger of your right hand to confirm this. Meteorologists call this anticyclonic rotation and refer to the sense of rotation as a vorticity minimum. Air is going down.

The graphic illustrates those circulations in my painting. The green lines are deformation zones (DZ's). Swirls shape the clouds in the sky and every swirl creates at least two deformation zones. The shapes of the deformation zones are determined by the (four) associated swirls. I have only included the strongest swirls in the graphic. The deformation zone drawn with a thick line is a bowed DZ. The deformation zone drawn with the thinner line is a double cyclonic DZ.

If you can read the DZ shape then you can deduce all you need to know about the sense and strength (angular momentum) of each swirl. The science also works in reverse. If you know the swirls then you know the shape of the associated deformation zone. Some people see the swirls first and some see the lines in the atmosphere. It does not matter.

One last thing... you only have one right hand so how can it create two different swirls? The truth is simple. There is only one swirl and I have described that in the "Unified Swirl Theory". Let your right thumb hand follow an imagery smoke ring in front of you. On the left side your thumb will point upward and on the right side the same thumb will point down. The cloud patterns and the meteorological jargon are just horizontal cross-sections through this larger three dimensional swirl. There is no need to make the weather and meteorology complicated. It really is quite simple and fun.

The yellow tinted sky on the west side of the upper ridge was certainly the next warm conveyor belt and autumn weather system. The red clouds at night are the harbinger of this next storm and not fair weather as the poem would suggest. Red skies at night may indeed indicate a sailor's delight as long as there are no red clouds in that skyscape.
