Abstract

Extratropical cyclones give rise to most of the high impact weather near Alaska, including heavy precipitation and strong winds. Thus it is important for many stakeholders to be warned of approaching periods of increased or decreased potential of storm activities. While individual cyclone tracks can be predicted out to about a week or so, from week 2 on, statistics summarizing cyclone activity, or storminess, are more useful. Storminess can be defined based on Lagrangian cyclone tracking or by Eulerian variance statistics. The outlook includes a combination of both methods. Lagrangian cyclone tracks provide information about where cyclones pass through and are more intuitive to users, while Eulerian variance statistics are expected to be more predictable and have been shown to be highly correlated with cyclone related weather. The outlook uses 6-hrly sub-seasonal forecasts from GEFSv12 and CFSv2. Hindcasts and operational forecasts from 1999-2016 have been used to assess the prediction skill. Our results show that the combined ensemble has higher skill than either individual ensemble. The combined ensemble shows good skill in predicting cyclone amplitude and frequency for week 2, and some skill in predicting these metrics for weeks 3-4. Models also show some skill in predicting the statistics of deep cyclones for week 2. For both week 2 and weeks 3-4, the prediction skills for an Eulerian sea level pressure variance storminess metric is significantly higher than those for Lagrangian track statistics. We expect that the skills for real time forecasts should be higher than those in the hindcasts since the operational ensembles are much larger than the hindcast ensembles. A publicly accessible web page will be developed to display the subseasonal predictions in real time. The web page will also contain information on climatology and forecast verification to enable users to make more informed use of the outlook.

Abstract

Measurements of aerosol chemical composition at the Barrow Atmospheric Baseline Observatory northeast of Utqiavik, Alaska have been conducted since 1997 to assess the impacts of the transport of pollutants from lower latitudes on Arctic atmospheric chemistry and climate. These measurements have been conducted alongside NOAA GML's observations of aerosol optical properties. Here we report on trends in Arctic haze aerosols in terms of composition, optical properties, and transport pathways. Between 1998 and 2013, haze season submicron non-sea salt sulfate and nitrate decreased by 2 and 1% per year, respectively. Supermicron nitrate decreased by 3% per year. Between 1998 and 2020, haze season submicron aerosol light scattering decreased by 1.6% per year and total scattering (particles less than 10 microns in diameter) decreased by 1.1% per year. Aerosol light absorption has also decreased during the haze season. Based on trajectories calculated with HYSPLIT, these decreasing trends appear to be due, at least in part, to a decrease in transport from the European sector to the Arctic. Summertime trends will also be discussed.

Abstract

The Research Network Activities for Sustained Coordinated Observations of Arctic Change (RNA CoObs) project seeks to support the Sustaining Arctic Observing Networks (SAON) Roadmap for Arctic Observing & Data Systems (ROADS). Through meetings, collaborations, and partnership with the Arctic Observing Summit (AOS) Food Security Working Group (FSWG) and other partners, the project will step through the elements of ROADS, including the identification of Shared Arctic Variables tied to societal benefits as defined by the FSWG, the capture of requirements for observing activities aimed at SAVs, and the design and adaption of information infrastructure. With a focus on the Pacific Arctic the project is meant to help explore and demonstrate how an internationally coordinated roadmap for Arctic observing can be put into action. A number of NOAA Alaska/Arctic activities are of relevance in this context, including NOAA's leadership in regional ocean observing, the U.S. Arctic Observing Network, and the Distributed Biological Observatory. The food security observing roadmap will guide observing activities in the Pacific Arctic and inform the ROADS process at the pan-Arctic scale. ROADS will then better serve operators, the research community, and decision-makers in their own efforts.

Abstract

Hydrologic forecasting in Alaska is challenging due largely to the sparse observational network of year-round, accurate precipitation and discharge gages. This problem is being addressed by creative new work in remote sensing and alternative gage technologies. Community-based monitoring is filling other important gaps. This talk will discuss these and possible future approaches to monitoring and forecasting hydrologic responses to temperature and precipitation on a spectrum of temporal and spatial scales.

ADAC, in support of the Alaska and Arctic Maritime Communications and Connectivity Analysis Project (AAMC&CA) Project Team, invites you to participate in a Maritime Communications and Connectivity Virtual Assessment.

This Virtual Assessment will consist of presentations on communications challenges and future uses for increased connectivity along with Industry participation in highlighting emerging technologies. The Virtual Assessment will include liberal use of virtual breakout groups to discuss near-term, mid-term, and long-term technologies and identify connectivity transition, utilization, and integration strategies and pathways. The Arctic Domain Awareness Center and the Alaska and Arctic Maritime Communications and Connectivity Analysis Project team look forward to your participation in this event as we seek to identify and further explore the current and future communications needs of Alaskan and Arctic operators and the key technologies with the potential to serve those needs in the future. This Virtual Assessment will be hosted via Zoom. The Zoom meeting information is included in the Agenda.

Mark Bertram, supervisory wildlife biologist for the Yukon Flats National Wildlife Refuge will guide you through the impacts of climatic change on resources in the Yukon Flats Basin. Extending 220 miles east-west along the Arctic Circle, the Basin lies between the Brooks Range to the north and the limestone peaks of the White Mountains to the south. The Yukon River bisects the Basin and contributes to the vast floodplain of lakes, ponds, and streams that dominate the landscape. The Basin, encompassed by the 11.1-million-acre Yukon Flats National Wildlife Refuge, provides critical habitat to world-renowned breeding populations of waterfowl, salmon and whitefish fisheries, and other important subsistence resources for over 1,200 local residents.
