A 400-mile blanket of fog has socked in California’s Central Valley for weeks. Scientists and meteorologists say the situations for such persistent cloud cowl are ripe: an early moist season, chilly temperatures and a secure, unmoving excessive strain system.
However take a stroll via X, Instagram or TikTok, and also you’ll see not everyone seems to be so sanguine.
Individuals are reporting that the fog has an odd consistency and that it’s nefariously suffering from black and white particles that don’t appear regular. They’re calling it “mysterious” and underscoring the identify “radiation” fog, which is the scientific descriptor for such pure fog occasions — not a sign that they carry radioactive materials.
An X consumer with the deal with Wall Road Apes posted a video of a person who stated he’s from Northern California drawing his finger alongside fog condensate on the grill of his truck. His finger comes up coated in white.
“What is that this s— proper right here?” the person says because the digital camera zooms in on his finger. “There’s one thing within the fog that I can’t clarify … Verify y’all … y’all loopy … What’s happening? They acquired asbestos in there.”
One other consumer, @wesleybrennan87, posted a photograph of two airplane contrails crisscrossing the sky via a break within the fog.
“For anybody following the dense Tule (Radiation) fog within the California Valley, it lifted for a second right this moment, simply to see they’ve been fairly energetic over our heads …” the consumer posted.
Scientists affirm there may be stuff within the fog. However what it’s and the place it comes from, they are saying, is disappointingly mundane.
The Central Valley is thought to have a few of the worst air air pollution within the nation.
And “fog is extremely vulnerable to pollution,” stated Peter Weiss-Penzias, a fog researcher at UC Santa Cruz.
Fog “droplets have a whole lot of floor space and are suspended within the air for fairly a very long time — days or perhaps weeks even — so throughout that point the water droplets can soak up a disproportionate amount of gasses and particles, that are in any other case often known as pollution,” he stated.
He stated whereas he hasn’t performed any analyses of the Central Valley fog throughout this newest occasion, it’s not laborious to think about what might be lurking within the droplets.
“It might be a complete alphabet soup of various issues. With all of the agriculture on this space, trade, vehicles, wooden smoke, there’s a complete bunch” of contenders, Weiss-Penzias stated.
Experiences of the fog changing into a gelatinous goo when left to sit down are additionally not fully stunning, he stated, contemplating all of the airborne organic materials — fungal spores, vitamins and algae — floating round that may additionally adhere to the Velcro-like drops of water.
He stated the excellent news is that whereas the first route of publicity for folks of this materials is inhalation, the fog droplets are comparatively massive. Which means when they’re breathed in, they gained’t go too deep into the lungs — not just like the particulate matter we inhale throughout sunny, dry days. That stuff can get manner down into lung tissue.
The larger concern is ingestion, because the fog covers crops or open water cisterns, he stated.
So ensure you’re washing your greens, and something you permit exterior that you just may nosh on later.
Dennis Baldocchi, a UC Berkeley fog researcher, agreed with Weiss-Penzias’ evaluation, and stated the storm system predicted to maneuver on this weekend will possible push the fog out and free the valley of its chilly, soiled scarf.
However, if a excessive strain system returns within the coming weeks, he wouldn’t be shocked to see the area encased in fog as soon as once more.
