Sitka Sailor's Delight

Sitka Sailor's Delight
8" x 10"
Oil $125.00 + $10. s/h

"Red sky at night, sailor's delight.  Red sky in morning, sailor's take warning."  I thought that this old adage was somewhat appropriate for my third Sitka, Alaska color study, but I've changed it a bit to suit my painting.  My rendition of this adage is:  Red sky and water at night, painter's delight.  Red sky and water in morning, painter's exploring."  Ok, it sort of works.  I call it artistic license.

As I often do, I googled to learn a bit more:
"Can weather lore truly predict the weather or seasons?
Weather lore concerning the appearance of the sky the conditions of the atmosphere, the type of movement of the clouds, and the direction of the winds may have a scientific basis and likely can predict the weather.

In order to understand why "Red sky at night, sailor's delight.  Red sky in morning, sailor's warning" can predict the weather, we must understand more about weather and the colors in the sky.

Usually, weather moves from west to east, blown by the westerly trade winds.  This means storm systems generally move in from the West.

The colors we see in the sky are due to the rays of sunlight being split into colors of the spectrum as they pass through the atmosphere and ricochet off the water vapor and particles in the atmosphere.  The amounts of water vapor and dust particles in the atmosphere are good indicators of weather conditions.  They also determine which colors we will see in the sky.

During sunrise and sunset the sun is low in the sky, and it transmits light through the thickest part of the atmosphere.  A red sky suggests an atmosphere loaded with dust and moisture particles.  We see the red, because red wavelengths (the longest in the color spectrum) are breaking through the atmosphere.  The shorter wavelengths, such as blue, are scattered and broken up.

Red sky at night, sailors delight.
When we see a red sky at night, this means that the setting sun is sending its light through a high concentration of dust particles.  This usually indicates high pressure and stable air coming in from the west.  Basically good weather will follow.

Red sky in morning, sailor's warming.
A red sunrise reflects the dust particles of a system that has just passed from the west.  This indicates that a storm system may be moving to the east.  If the morning sky is a deep fiery red, it means a high water content int he atmosphere.  So, rain is on its way."

Hi Pam, I love your Sitka paintings. The colors are gorgeous and lovely for me to see. I saw Sitka in the mist. Also beautiful but not as much as this.

Julie, thanks so much. Sitka is often in the mist!! That's probably how most people see it.

Thank you Sherry. I think that it's fun to occasionally throw in tidbits of other related info!!
