Sentences with phrase «california precipitation event»

This airmass is also expected to be incredibly warm for a California precipitation event; freezing levels could be as high as 10,000 feet or even higher during the initial part of the storm, with rain (instead of snow) expected at even very high mountain locations.

Not exact matches

The authors predict a 25 % rise in the frequency of precipitation whiplash events by the end of the twenty - first century in northern California, increasing up to 100 % in southern California.

Daniel Swain and colleagues model how the frequency of these rapid, year - to - year transitions from extreme dry to wet conditions — which they dub «precipitation whiplash events» — may change in California's future as a consequence of man - made warming.

There are high hopes in California that the robust El Niño event will continue through the year and bring strong winter precipitation to help put a dent into the years - long drought there.

Another study, published in Geophysical Research Letters in late December of last year, found that California's precipitation deficits alone do not make this drought a historic event.

Abstract The Key Role of Heavy Precipitation Events in Climate Model Disagreements of Future Annual Precipitation Changes in California Climate model simulations disagree on whether future precipitation will increase or decrease over California, which has impeded efforts to anticipate and adapt to human - induced climate cPrecipitation Events in Climate Model Disagreements of Future Annual Precipitation Changes in California Climate model simulations disagree on whether future precipitation will increase or decrease over California, which has impeded efforts to anticipate and adapt to human - induced climate cPrecipitation Changes in California Climate model simulations disagree on whether future precipitation will increase or decrease over California, which has impeded efforts to anticipate and adapt to human - induced climate cprecipitation will increase or decrease over California, which has impeded efforts to anticipate and adapt to human - induced climate change........

Since essentially the entire geographic region experiences a qualitatively Mediterranean climate — with strongly seasonal precipitation and a very distinct (but globally uncommon) summer dry season — most of California's annual precipitation derives from a relatively small handful of major cool - season precipitation events.

* This means that the maximum 12 - month magnitude of the precipitation deficits in California during the current drought have exceeded those during all previous droughts in living memory — including both the 1976 - 1977 and 1987 - 1992 events.

[26] Historically, the most intense storms and precipitation events in California have been tied to wintertime atmospheric rivers that fed on high levels of water vapor in the air.

In addition, the probability of a — 1.5 SD precipitation anomaly increases in spring (P < 0.001) and autumn (P = 0.01) in 2006 — 2080 relative to 1920 — 2005, with spring occurrence increasing by ∼ 75 % and autumn occurrence increasing by ∼ 44 % — which represents a substantial and statistically significant increase in the risk of extremely low - precipitation events at both margins of California's wet season.

Indeed, our results show that even in the absence of trends in mean precipitation — or trends in the occurrence of extremely low - precipitation events — the risk of severe drought in California has already increased due to extremely warm conditions induced by anthropogenic global warming.

But California droughts are also fundamentally linked to the quantities and timing of precipitation, the dynamics of storm formation in the Pacific Ocean, the impacts of climate change on the frequency and intensity of El Niño and La Niña events and the Pacific Decadal Oscillation, and the behavior of the jet stream as conditions in the Arctic change.

The increasingly extreme behavior of precipitation in California — which could very well occur without much of a change in California's overall average precipitation — may increase the risk of both drought and flood events in the state.

A large ensemble of climate model simulations suggests that the frequency of extreme wet - to - dry precipitation events will increase by 25 % to 100 % across California due to anthropogenic forcing.

The hope in California is that the large amounts of precipitation usually associated with extreme El Niño events would lessen the impacts of the state's multi-year drought by partly refilling reservoirs and groundwater, even as scientists caution that this might not happen to the degree needed to alter the present situation.
