Winter Solstice, and a Long-Term Weather Forecast

The shortest day of the year, a critical turning point for past cultures, now serves as a time of reflection.

The winter solstice will arrive Wednesday night marking an astronomical turning point observed since ancient times that also presents a chance to consider the long-term winter weather forecast.

The solstice will occur Dec. 21 at 9:30 p.m local time, signaling the moment when the North Pole tilts away from the sun at its furthest point and the sun makes it most southerly arc across the horizon. For those of us in the Northern Hemisphere, it marks the shortest day and the longest night of the year.

For many ancient and indigenous cultures throughout history, the winter solstice marked a critical time for survival. 

"It was really regarded as a time of potentially great crisis," said Ed Krupp, an astronomer and director of the Griffith Observatory, who specializes in ancient traditional astronomy.

It used to be necessary for people "to engage in ritual activity in order to help the cosmos go the way that benefits people," Krupp said.

Many of these rituals involved lighting candles or fires to symbolize the return of the sun and ensure the survival of a people. The winter solstice, on the bright side, marks the point at which the North Pole begins its steady, but inevitable return toward the sun. The days will get longer after the winter solstice and the sun will appear to climb higher in the sky.

The weather, unfortunately, takes considerable more time to catch up with the sun. 

This season's long term winter weather forecast, according to the National Weather Service, calls for below normal temperatures and below normal precipitation. Just how much below remains to be seen. 

"So far, we had a cool summer and a cool fall," said Stuart Seto, a weather specialist with the National Weather Service. "If La Niña plays out, we'll have a colder winter, too."

Last winter's onslaught of rain and snow storms in Southern California made it an atypical La Niña winter.

La Niña is a weather phenomenon involving cooler sea surface temperatures in the central and eastern tropical Pacific Ocean that interact with eastward trade winds to affect global weather patterns. For Southern California, La Niña makes the winters colder and drier. 

The Old Farmer's Almanac agrees with this winter's weather predictions for a cooler and drier climate in Southern California. 

Although the weather may be unpredictable, winter solstices have served to remind humans of the natural cycle of things; that every winter eventually turns into spring and that darkness eventually succumbs to light.
