What is tule fog?

Tule fog (pronounced too-lee ) is a very strong fog that gather in parts of California during the rainy season of late autumn and winter. It is a type of radiation fog caused by a combination of increased humidity due to rain and rapid cooling due to a longer night. This fog causes very low visibility and is the cause of many accidents every year. The tule fog is created because the warm air rises. Cold mountain air descends into the valley during the night and is imprisoned due to low air outlet throughout the central valley. Colder temperatures and reduced sunlight of the winter months cause the fog to burn very slowly and can persist for days. The air at the top is warmer, dry and lighter, and is used to capture heavy, wet fog in the valley.

Visibility in tule fog ranges from 600 feet (183 meters) to 1 foot (30.5 cm). Operation in zero visibility of fog was the cause of fatal accidents, usually due to multiple pile of vehicles. Such disasters are oftenImproved by the accompanying weather conditions, including drizzle and black ice, causing the road to be slippery, but is invisible to the driver.

To stay safe during the tough season season, people should avoid driving in the central valley as much as possible and at any time, and decide on the train service at any time. Those who have to drive should be aware that safe speeds are significantly below the published speed limit when visibility is low. Drivers should use low beam headlamps, as high rays can bounce back into the car, which further reduces visibility. They should also carefully listen to traffic when it is difficult to see and be particularly careful at intersections and avoid those who have Continuous Cross Traffic whenever possible. Drivers must also follow all California highway patrol instructions.
