ArKStorm assesses potential flood risk The anticipated flooding impacts from the within the Santa Clara River basin and ArKStorm will not be as devastating in presents that risk through a number of Ventura County as will be experienced event scenarios that are likely to occur elsewhere in California (Los Angeles and during a major storm. Orange counties, Central Valley). Ventura County is generally situated at the fringe of the storms. ArKStorm is a risk assessment tool that can be used to identify community infrastructure (examples: bridges, railroads, gas lines) and critical facilities (examples: sewage treatment plant, hospitals) that are likely to be affected by flood-related impacts and so that local emergency response providers have a better understanding of where to focus their attention and allocate resources prior to, during and after a major storm. ArkStorm maps will illustrate the maximum impact of flooding likely to be experienced during the storm along the entire Santa Clara River corridor. Based on this mapped impact, a number of flooding event scenarios will be created and analyzed by participating community emergency response agencies to assess how best to respond. .

The Arkstorm Scenario: California's Other "Big One"
The San Bernardino County Museum Guest Lecture Series The ARkStorm Scenario: California’s other “Big One” Lucy Jones • U. S. Geological Survey Wednesday, January 25, 2012 • 7:30pm • Free Admission Landslides and debris flows. Coastal innundation and flooding. Infrastructure damage. Pollution. Dr. Lucy Jones will give an overview of the ARkStorm Scenario—catastrophic flooding resulting from a month-long deluge like was seen in 1862, and four larger such events in the past 100 years. This type of storm, resulting from atmospheric rivers of moisture, is plausible, and a smaller version hit San Bernardino in December of 2010 with a week’s worth of rain that impacted Highland and the surrounding communities. The ARkStorm Scenario explores the resulting impacts to our social structure and can be used to understand how California’s “other” Big One can be more expensive than a large San Andreas earthquake. Dr. Lucy Jones has been a seismologist with the US Geological Survey and a Visiting Research Associate at the Seismological Laboratory of Caltech since 1983. She currently serves as the Science Advisor for the Natural Hazards Mission of the US Geological Survey, leading the long-term science planning for natural hazards research. She also leads the SAFRR Project: Science Application for Risk Reduction to apply USGS science to reduce risk in communities across the nation. Dr. Jones has written more than 90 papers on research seismology with primary interest in the physics of earthquakes, foreshocks, and earthquake hazard assessment, especially in southern California. She serves on the California Earthquake Prediction Evaluation Council and was a Commissioner of the California Seismic Safety Commission from 2002 to 2009.

Atmospheric rivers (ARs) account for more than 75 % of heavy precipitation events and nearly all of the extreme ﬂooding events along the Olympic Mountains and western Cascade Mountains of western Washing- ton state. In a warmer climate, ARs in this region are projected to become more frequent and intense, primarily due to increases in atmospheric water vapor. However, it is unclear how the changes in water vapor transport will affect regional ﬂooding and associated economic impacts. In this work we present an integrated model- ing system to quantify the atmospheric–hydrologic–hydraulic and economic impacts of the December 2007 AR event that impacted the Chehalis River basin in western Washington.

Increasing Precipitation Volatility in Twenty-First-Century California
ARTICLES https://doi.org/10.1038/s41558-018-0140-y Increasing precipitation volatility in twenty-first- century California Daniel L. Swain 1,2*, Baird Langenbrunner3,4, J. David Neelin3 and Alex Hall3 Mediterranean climate regimes are particularly susceptible to rapid shifts between drought and flood—of which, California’s rapid transition from record multi-year dryness between 2012 and 2016 to extreme wetness during the 2016–2017 winter pro- vides a dramatic example. Projected future changes in such dry-to-wet events, however, remain inadequately quantified, which we investigate here using the Community Earth System Model Large Ensemble of climate model simulations. Anthropogenic forcing is found to yield large twenty-first-century increases in the frequency of wet extremes, including a more than threefold increase in sub-seasonal events comparable to California’s ‘Great Flood of 1862’. Smaller but statistically robust increases in dry extremes are also apparent. As a consequence, a 25% to 100% increase in extreme dry-to-wet precipitation events is pro- jected, despite only modest changes in mean precipitation. Such hydrological cycle intensification would seriously challenge California’s existing water storage, conveyance and flood control infrastructure. editerranean climate regimes are renowned for their dis- however, has suggested an increased likelihood of wet years20–23 tinctively dry summers and relatively wet winters—a glob- and subsequent flood risk9,24 in California—which is consistent ally unusual combination1.

Emergence of the Concept of Atmospheric Rivers
Emergence of the Concept of Atmospheric Rivers F. Martin Ralph UC San Diego/Scripps Institution of Oceanography International Atmospheric Rivers Conference (IARC) Keynote Presentation 8 August 2016, La Jolla, CA Outline Purpose: Describe major milestones in development of the AR concept • 1970s and 1980s: Underlying concepts established • 1990s: Global perspectives lead to the term “atmospheric river” (AR) • 2000s: U.S. West Coast experiments, forecasts and practical goals focus on ARs • 2010-2015: The concept matures, science and practical applications grow • 2016 and beyond: A diverse community exists and is pursuing a range of promising science and application directions The low-level jet Browning described the LLJ in the region of the polar cold front as a cork-screw like motion that can advance warm moist air both poleward and upward Browning and Pardoe (1973-QJRMS) Slide courtesy of J. Cordeira Warm and Cold Conveyor Belt Concepts • 3D kinematic and thermodynamic Cold conveyor belt schematic • Warm conveyor belt – Ahead of cold front – Ascends over warm front – Represents sensible and latent heat Image adapted from Carlson (1980) Warm conveyor belt Slide courtesy of J. Cordeira Zhu & Newell (1998) concluded in a 3-year ECMWF model diagnostic study: 1) 95% of meridional water vapor flux occurs in narrow plumes in <10% of zonal circumference. 2) There are typically 3-5 of these narrow plumes within a hemisphere at any one moment. 3) They coined the term “atmospheric river” (AR) to reflect the narrow character of plumes. 4) ARs are very important from a global water cycle perspective. Atmospheric Rivers are responsible for 90 - 95% of the total global meridional water vapor transport at midlatitudes, and yet constitute <10% of the Earth’s circumference at those latitudes.

This article is published with open access at Springerlink.com Abstract The USGS Multihazards Project is working with numerous agencies to eval- uate and plan for hazards and damages that could be caused by extreme winter storms impacting California. Atmospheric and hydrological aspects of a hypothetical storm sce- nario have been quantified as a basis for estimation of human, infrastructure, economic, and environmental impacts for emergency-preparedness and flood-planning exercises. In order to ensure scientific defensibility and necessary levels of detail in the scenario description, selected historical storm episodes were concatentated to describe a rapid arrival of several major storms over the state, yielding precipitation totals and runoff rates beyond those occurring during the individual historical storms. This concatenation allowed the scenario designers to avoid arbitrary scalings and is based on historical occasions from the 19th and 20th Centuries when storms have stalled over the state and when extreme M.

AR Science, Natural Hazards Risk Reduction, and Arkstorm
AR Science, Natural Hazards Risk Reduction, and ARkStorm Dale Cox, US Geological Survey, 6000 J Street Placer Hall, Sacramento, CA 95819 USA; [email protected]; (916) 997-4209 Michael Dettinger, US Geological Survey, Carson City, NV USA F Martin Ralph, Center for Western Weather and Water Extremes, Scripps Institution of Oceanography, La Jolla, CA USA The ARkStorm Scenario project began in 2008, led by the USGS Multi-Hazards Demonstration Project (now USGS Science Application for Risk Reduction SAFRR) in an effort to innovate the application of science for the purpose of societal reductions of natural-hazard risks associated with large atmospheric river (AR) storms on the West Coast of the US, specifically focused on California. The effort involved participation and contributions from many federal, state and academic organizations including NOAA’s Environmental Systems Laboratory. The ARkStorm project used new understanding of atmospheric river physics, combined with the downscaled meteorological data describing two recent ARs (in 1969 and 1986), to describe and model a prolonged sequence of back-to-back storms similar to the those that bankrupted California in 1862. With details of this scientifically plausible (but not worst-case) scenario in hand, the ARkStorm team engaged the flood and levee community to identify plausible flooding extents and durations, created a coastal-storm inundation model (CoSMoS), and the California’s first landslide susceptibility map (CGS), to better understand secondary meteorological and geophysical hazards (flood, wind, landslide, coastal erosion and inundation) across California. Thenceforth, physical damages to homes, infrastructure, agriculture, and the environment were estimated to calculate the likely social and economic damages to California and the Nation.
