A River Runs above Us – Hakai Magazine

In mid-November 2021, a great storm begins brewing in the central Pacific Ocean north of Hawai‘i. Especially warm water, heated by the sun, steams off the sea surface and funnels into the sky.
A tendril of this floating moisture sweeps eastward across the ocean. It rides the winds for a day until it reaches the coasts of British Columbia and Washington State. There, the storm hits air turbulence, which pushes it into position—straight over British Columbia’s Fraser River valley….
Volcano? Climate change? Bad luck? – the Los Angeles Times

As winter approached, few anticipated what was about to hit California. Mired in a serious drought, the state was suddenly battered by an onslaught of 31 atmospheric river storms in a matter of months. While the number alone isn’t exceptional, the location, intensity and duration of these storms had a transforming effect on California’s climate. Record snowfall. Deadly flooding…But one thing remains a mystery: Why did so many of these bands of water vapor, many back-to-back, slam into California?
Bomb cyclone, atmospheric river, polar vortex: How our weather terminology has grown with recent wild storms – the Los Angeles Times

Californians have been warned over the past few months about weather ranging from a “vicious heat dome” to back-to-back “atmospheric rivers,” and the always-concerning “bomb cyclone.” While it might feel as though recent weather has been dominated by a string of new phenomena, experts say these terms and events are well-established in the scientific world but simply novel to much of general public…
On the Coast: Before and After the Parade of Atmospheric Rivers – Planet Snapshots issue 59 via Medium

California is left drenched, flooded, and perhaps a little hopeful after recurring atmospheric rivers pummeled the state for 2 weeks straight. The rains are a small reprieve for the area’s years-long drought. But the sheer volume of rainfall was much more than the parched landscape could handle. With a turn of the faucet, the state went from too dry to too wet in what’s called a “weather whiplash,” transforming the Golden State to shades of brown…
How Do California’s Storms Weigh In Compared With History’s Big Ones? – the New York Times

The storms that have walloped California in fierce waves since last month have left many communities cleaning up and digging out from flooding and landslides. By one metric, though, the state has seen much worse…
Global Weather Patterns and Coastlines
Coasts are sensitive to sea level rise, changes in the frequency and intensity of storms, increases in precipitation, and warmer ocean temperatures. In addition, rising atmospheric concentrations of carbon dioxide (CO2) are causing the oceans to absorb more of the gas and become more acidic. This rising acidity can have significant impacts on coastal and marine ecosystems.
The impacts of climate change are likely to worsen problems that coastal areas already face. Confronting existing challenges that affect man-made infrastructure and coastal ecosystems, such as shoreline erosion, coastal flooding, and water pollution, is already a concern in many areas. Addressing the additional stress of climate change may require new approaches to managing land, water, waste, and ecosystems…
‘Inside we are all struggling’: storm-bruised California begins recovery – the Guardian

From hillside towns like Felton to the picturesque coastal enclave of Capitola, the long road to recovery from disaster is only beginning. The county was declared a major disaster zone by Joe Biden, who visited Capitola on Thursday to survey the damage and said it would “take years to rebuild”…
Atmospheric rivers hitting California will become even more intense. Here’s how they work – the San Francisco Chronicle

The same weather that replenishes California water supplies could bring the next megaflood.
A procession of storms is drenching Northern California this week, with rainfall already topping 2 inches in San Francisco and surpassing 8 inches in the Santa Cruz Mountains. More precipitation is on tap through the weekend, prompting concerns of widespread urban flooding and potential landslides…
What Will ‘Weather Whiplash’ Mean for California? – the New York Times

California is built upon the great gamble of irrigation. Left alone, much of the land in the Western United States would be inhospitable to teeming cities. But we’re Americans — we couldn’t let the desert stand in our way.
More than a century ago, the United States Bureau of Land Reclamation began taming the water in the West…
