“Bomb Cyclone” Winter Storm to Clobber California

A major winter storm, with winds gusting up to near hurricane strength is moving towards northern California. Dubbed a “bomb cyclone” due to rapid central pressure drop, it more than qualifies for the 24 millibars (mb) in 24 hours “bomb” cyclone designation.

As of 11AM Wednesday Jan 4th, the central pressure of the storm as it was just off the California coast was 28.33 inches (959.36 millibars) as seen in the graphic below. That pressure is lower than the centrral pressure of many hurricanes.

The National Weather Service (NWS) has produced forecasts for areas of likely flooding that covers much of the Sacramento Valley and the north coast.

Because this winter storm is relatively warm, snow levels are averaging higher, causing rain to fall on snow-laden areas, creating snow-melt which will overwhelm already waterlogged soil, making for fast runoff into creeks and rivers.

The NWS has issued a Winter Storm Warning for the Northern Sierra Nevada.

Heavy snow expected. Total snow accumulations of 4 to 10 inches, except 6 to 18 inches west of Highway 395. Lowest valleys below 4000-4500 feet elevation are only expected to see up to 3 inches of snow.

Snow levels will start off below 4000 feet before briefly increasing to 5000-6000 feet Wednesday afternoon. Snow levels will then fall again to 4500-5000 feet Thursday. This storm will come in 2 parts, and areas east of Highway 395 may see a brief break Wednesday evening.

For the areas Near lake Tahoe, the NWS advises the situation is even worse:

Heavy snow expected. Total snow accumulations of 8 to   14 inches, except 1 to 2 feet above 7000 feet. Localized amounts up to 3 feet are expected for the Sierra crest. Winds gusting as high as 100 mph over Sierra ridgelines with gusts up to 40 mph in the Tahoe Basin.

In addition, widespread damaging winds are forecast from this winter storm.

Winds on the valley floor are expected to gust as high as 60 mph, with higher elevations seeing stronger wind gusts.

If the real problem is that the right amount of rain is falling but in the wrong places, then we should consider building a national (or even world) water-pipeline grid to move it around, as we do with electricity. As far as I can tell, all the reasons we don’t are political, not technical.

So … will this result in permanent drought or permanent flooding?
Both have been claimed as the result of using fossil fuel.
Or maybe the claim itself is the permanent “bomb”?
Have “winter bomb cyclones” happened on the West Coast before?

By Tim Stelloh
powerful storm that drenched the West Coast with record-breaking rainfall and hurricane-force winds triggered landslides, flooded roads and left two people dead in Washington State.
It also resurrected one of California’s most iconic natural features — Yosemite Falls.
Before a “bomb cyclone” slammed into the state Sunday, dropping nearly a foot of rain in some parts of a region strained by a climate change-fueled megadrought, the 2,425-foot falls had all but vanished, as often happens by late summer or fall.
But by Monday, more than six inches of rain had fallen across Yosemite Valley in 36 hours, the park said on Facebook. And the falls roared back to life, as one observer put it on Twitter.

The published rationale for plans like that is that building enough infrastructure would encourage more people to move here.

If you don’t want that to happen, why not just ban it? Create transferable permits to live in this state. Issue one per legal resident. Then stop issuing them.

Of course now that California’s tax (and other) laws are driving more people to leave the state than come here, I guess the permits are no longer necessary. What a waste of the nice climate, though.

The (non) problem was that the delta smelt was helped out of existence by Fish and Wildlife by introducing a similar smelt to try to help. First the Delta disappeared then the replacement slowly went away.

In 24 hours, an Arctic cyclone (stratospheric intrusion) will reach the California coast. A lot of snow will fall in the mountains. We warn that roads will be impassable during the snowstorm. As much rain may fall in the lowlands as in hurricanes.

When I was constantly hauling loads back and forth across the country I would do my very best to use either I-10 or I-40 during the winter months. But if I had to use a northern Interstate when going to or coming from the left coast during the winter it would be I-80 rather than I-70 or I-90.

I-80 goes through a pass very near that the Donner party tried to use and in fact when using the pass truckers often refer to it as going through “the Donner”.

“Bomb cyclone” is a faddish phrase that’s worse than useless because it’s misleading. A “bomb” is a manufactured device that explodes. A “cyclone” is a natural, low pressure system where wind rushes towards the center. Calling an implosion an explosion doesn’t work, even as metaphor.

The scary term, “bomb cyclone” is another example of weather media striving to be lurid and frightening, rather than precise, which is what meteorology — and science in general — used to strive for. Neologisms for ancient, normal phenomena push understanding in the wrong direction.

More intellectual degradation in service of grabbing eyeballs does NOT serve the public well.

When weather reporting returns to terms like “storm,” and “intense low” we’ll understand more, which ought to be the purpose of science in the first place.

Okay, time to do some digging. I always thought that the term arose after the New England Blizzard of 1978, the reference standard for a blizzard by nearly all who lived through it.

I found many references to “a [the] 1980 article in the journal Monthly Weather Review.” I finally found it in the October issue at https://journals.ametsoc.org/view/journals/mwre/108/10/1520-0493_1980_108_1589_sdcot_2_0_co_2.xml?tab_body=pdf

Synoptic-Dynamic Climatology of the “Bomb”

Frederick Sanders and John R. Gyakum

Abstract

By defining a “bomb” as an extratropical surface cyclone whose central pressure fall averages at least 1 mb [per hour] for 24 h, we have studied this explosive cyclogenesis in the Northern Hemisphere during the period September 1976–May 1979. This predominantly maritime, cold-season event is usually found ∼400 n mi downstream from a mobile 500 mb trough, within or poleward of the maximum westerlies, and within or ahead of the planetary-scale troughs.

So, blame it on Fred Sanders. Apparently there are other references to storms bombing out in the 1940s.

And yes, the term is being used to describe any storm that undergoes bombogenesis – commonly 24 mb pressure fall in 24 hours, though I noted an equation involving the latitude, IIRC, sin(latitude)/sin(60) mb per hour to accommodate the faster development at higher latitudes.

As for lurid and frightening, note that cold and warm fronts refer to wartime battle fronts, only between air masses, not humans.

Even blizzard. From https://www.southcoasttoday.com/story/news/2022/01/28/winter-weather-definition-blizzard-bomb-cyclone-bombogensis-thundersnow-nor-easter-windchill/9242383002/

In the 1870s, an Iowa newspaper used the word “blizzard” to describe a snowstorm. Previously, the term blizzard referred to a canon shot or a volley of musket fire. By the 1880s, the use of the word blizzard was used by many across the United States and in England.

Perhaps a meteorologist could show a record of how many of these storms with precipitous pressure drops have actually hit the central California coast. Specifically fronts which cause drops equal to or in excess of “24 millibars (mb) in 24 hours”.

My own memory is short but I would guess Colorado has suffered similar crazy barometric drops somwhere across the state just about every year. We had one excitingly dubbed a “bomb cyclone” just before Christmas, December 22. Fort-five degrees and windy as hell when I went into King Soopers; 28 degrees when I came out – and I wasn’t just squeezing the Charmin.

In any case, all those atmospheric rivers of snow have left the Colorado snowpack in good shape for another year. Six of the eight major drainages are way above the average for this time of year and the Western Slope looks particularly good. Colorado Headwaters are at 130% of average; Yampa and the White at 150%.

Best regards for the year of the rabbit.

I suppose the “bomb cyclone” (or “the cyclone bombed out and”) brought _both_ Blizzards in 1978 works for me.

The only names I’m familiar with for rain storms that bomb out and stay rain or mostly rain are “nor’easter” along the Atlantic coast and the “Witch of November” in the upper Mississippi River and Great Lakes.

However, I do agree “bomb cyclone” is way overused.

Totally agree. When I was younger (back when I was a kid they still had the tv meteorologist moving warm and cold fronts and highs and lows around on an actual board rather than a computer graphic) things were simple and direct. Storms were just storms….rain was just rain – maybe heavy rain, but rain. A snow storm was just that – a snow storm! Hot weather was hot weather, and not often called a heat wave unless it lasted many days…

“Bomb cyclone” is a highly prejudicial term designed to elicit fear and play into the “warming climate causes extreme weather” bullshit. Entirely made up. It’s just a storm, period.

It’s just a low pressure system, and not at all unusual in the size of storm and wind velocity, or in the volume of snow and rain it is bringing to an area that the warmunists have been wailing about drought over for the last several years.

From another wiki article: https://en.wikipedia.org/wiki/California_flood_of_1605

“The California flood of 1605 was a massive flood that submerged large portions of present-day California (once known as Alta California). The megaflood was a result of sustained major rain storms across the region, enhanced by an unusually powerful atmospheric river. The flooding affected the indigenous peoples of California, in pre-industrial advancement populations.

In addition to this event, geologic evidence indicates that other “megafloods” occurred in the California region in the following years A.D.: 212, 440, 603, 1029, c. 1300, 1418, 1750, 1810, and 1861–62. United States Geological Survey sediment research revealed that the 1605 flood deposited a layer of silt two inches thick at the Santa Barbara basin, indicating that it was the worst flood event of the past 2,000 years, being at least 50% more powerful than any of the others recorded based on geological evidence.”

That’s partly from the miscommunication continually received by most people about the weather.

What is drummed into people’s heads is the incorrectly stated notion that a 30-year average is “NORMAL,” when it is nothing of the kind; it is just a long-term average, which at the end of the day would more correctly be described as a “midpoint of extremes.”

California’s natural climate is drought and flood, flood and drought. I grew up in Los Angeles, and lived in South California until I was 22 years old. I fought brush fires, I fought flooding and mudslides and raging creeks that were washing coastal cities into the sea.

During the same period, we suffered (lack of) water emergencies on a regular basis.

That is the climate there — these storms are not the exception but the rule.

Many will comment on the historic storm that left nearly the entire Central Valley of California a lake in the 1800s. All the wonderful rich soil is there in the Central Valley because of these types of events washing the hills and mountains into the valley.

Note that this series of storms is bring much needed water and snow pack to the help modify the long-term drought across the entire Southwest.
