There is a phenomenon in Central California called "Tule Fog" that is so dangerous! Every year they have accidents, but about once a decade they have HUGE multi-car pile ups that shut down major highways for miles. This year, and the season for it is not over yet, there was a 100-car pile up that killed two people.

By GARANCE BURKE, Associated Press Writer FRESNO, Calif. - More than 100 cars and trucks crashed on a fog-shrouded freeway Saturday, killing at least two people and injuring dozens more, the California Highway Patrol said. Eighteen big rigs were involved in the massive pileup on Highway 99 just south of Fresno as patches of dense fog obscured visibility on the heavily traveled roadway, CHP officials said. "It looked like something out of a movie, walking up and seeing all the cars mangled and crushed," CHP Officer Paul Solorzano Jr. said. A 6-year-old boy and a 28-year-old man traveling in separate vehicles were killed in the chain-reaction collisions around 7:45 a.m., he said. "There was probably 2-foot visibility in the fog when I got here. It was really bad," said Mike Bowman, a spokesman for the California Department of Forestry and Fire Protection. "It looked like chaos. Cars were backed up on top of each other." ......Thick seasonal fog known as "Tule fog" typically occurs in Central California in the late fall and winter. A stretch of the highway several miles south was the scene of an autumn 74-car pileup nearly a decade ago that left two people dead. |

I haven't heard of that movie. No, it's not from pollution, but a natural occurrence because of the geography.

Tule fog is a radiation fog, which condenses when there is a high relative humidity - typically after a heavy rain - calm winds, and rapid cooling during the night. The nights are longer in the winter months, which creates rapid ground cooling, and thereby a pronounced temperature inversion at a low altitude. In California, tule fog can extend from Bakersfield to Red Bluff. Tule fog occasionally drifts as far west as the San Francisco Bay Area, even drifting westward out the Golden Gate, opposite to the usual course of summertime ocean fog. It is formed when cold mountain air flows downslope into the valley during the night, pooling in the low areas until it fills the valley to the "brim" formed by the Coast Ranges and the Sierra Nevada. This occurs because most areas in the Great Central Valley have little or no air drainage below the level of mountain passes. Because of the density of the cold air in the winter, winds are not able to dislodge the fog and the high pressure of the warmer air above the mountaintops presses down on the cold air trapped in the valley, resulting in a dense, immobile fog that can last for days undisturbed. During the summer, the sun is warmer and better able to mix out the fog. |
