Sun and rain create beautiful backdrop

Bright vivid rainbows formed across Drayton’s Passage from us yesterday, creating a beautiful backdrop for our hungry hummingbirds.

Good morning Longbranch.

There is a bit of a chill in the air. It is currently 51 degrees, but it sure feels colder than that. It is overcast and the weather geeks are saying we will surely get a few rain showers today. Our high today will top out at 63.

The one thing I love about our weather this time of year is how the intermittent sunshine creates rainbows and dramatic skies. Rainbows are just comforting to me. They impress most observers.

“I love what the light is doing like it is doing right now,” my lovely bride said as rainbows formed just across Drayton’a Passage over Anderson Island.

“I need a copy of that,” a neighbor said as he watched me snap a few frames of the unfolding Puget Sound light show.

It seemed like my neighborhood was out on the bank enjoying the spectacle. But how are rainbows formed? Here is what wisegeek — — says:

“Rainbows are a striking and beautiful meteorological phenomenon caused by the refraction of light. In order for rainbows to form, the sun must be near the horizon, and there must be a heavy fog, mist, or rain opposite the sun. An observer standing between the sun and the rainbow would see a 180 degree arc of colors which run through the visible spectrum from red to violet. In some cases, if conditions are right, double rainbows will form, with a pale rainbow in reversed colors above the primary rainbow, and in other instances, a fully circular rainbow has been observed, usually from inside an aircraft flying over the Earth.

“Although rainbows have been observed, written about, and depicted in art for centuries, their cause was not understood until physics began to explore the properties of light. Essentially, the cause of a rainbow is the reflection of sunlight through individual drops of water. Light enters the water and reflects from the opposite side of the water drop, bouncing back through the point of entry. Because the angle or refraction of the light changes as it bounces back, it filters the light into different colors, which arrange themselves with red at the top and violet at the bottom because red is the longest wave length, and violet is the shortest.”

So, bundle up Longbranch. We can all look forward to warmer temperatures tomorrow and Monday.
