Climate, salmon, and fishing communities: Collaborative, solutions-oriented science for Alaska

Online only

Speaker: Erik Schoen, International Arctic Research Center, UAF As Alaska's salmon respond to a rapidly changing environment, our fishing communities are experiencing record highs, disastrous lows, and uncertainty about what the future will bring. Climatic conditions affect salmon throughout their life cycle, from freshwater to the ocean and back. Climate can also influence salmon indirectly…

VAWS: The Alaska Aviation Weather Unit and Volcanic Ash Advisory Center

Speaker: Joshua Maloy (National Weather Service) The Alaska Aviation Weather Unit/Anchorage Volcanic Ash Advisory Center is a dual office that has both meteorological watch office and volcanic ash advisory center responsibilities. Falling under the auspices of NOAAs National Weather Service, the dual-office is located in Anchorage, AK. The presentation will provide an overview of operations,…

Alaska Fire Season 2022: Focus on Southwest Alaska and Impacts on Vegetation and Fuels

Online only

Speakers: Rick Thoman (ACCAP Climate Specialist) and JJ Frost (ABR, Inc. Plant Biologist) The 2022 fire season in Alaska was unprecedented. Southwest Alaska experienced record-breaking fires that impacted local communities and challenged management resources. This webinar will review the weather, climate, and ecological factors that contributed to the severe wildfire season, with an in-depth look…

Laying the Foundation for Resilient Coastal Communities

Speaker: Rich Buzard The UAF Arctic Coastal Geoscience Lab uses a combination of remote sensing, ground and aerial surveys and citizen science to measure erosion and flooding in several Alaskan villages. During this webinar Rich will describe their work monitoring coastal erosion and laying the foundation for resilience in coastal Alaskan communities.

Southeast Alaska Drought

Join us to review the SE Alaska Drought Report. We'll discuss drought history, causes, and impacts. Select community perspectives will be highlighted.

Arctic Report Card: Background and Key Finding

Speakers: Rick Thoman (ACCAP Climate Specialist), John Walsh (Climate Scientist) and Robb Kaler (USFW Migratory Bird Management) During this month's VAWS webinar, we will review the process used to create…

Moose on the Move: Science to Prevent Moose-Vehicle Collisions in a Changing Climate

This webinar will draw a link between seasonal changes in driving difficulty and moose movements that lead to a predictable spike in moose-vehicle collisions during winter. We can use this knowledge to predict the times and places where collision risk is highest, and ultimately reduce avoidable human and animal suffering.

Geolinguistic Evidence of Ahtna/Dene Presence at High-water Levels of Glacial Lake Atna

Speaker: James Kari, Emeritus Alaska Native Language Center, University of Alaska Fairbanks A group of about 20 Ahtna place names termed "The Nen' Yese' Ensemble" are very informative of the geology and hydrology at the Tyone Spillway in the Copper River Basin. Seven or eight patterned duplications indicate rule-driven spatial-temporal seriation at high water levels…

March 2023 NWS Alaska Climate Outlook Briefing

Speaker: Rick Thoman, ACCAP Climate Specialist We will review recent and current climate conditions around Alaska, discuss forecast tools, and finish up with the Climate Prediction Center’s forecast for April…

VAWS: Predicting pyroCumulonimbus (pyroCb) events through remote sensing resources in support of National Weather Service and firefighting agencies

This presentation will examine the efficacy of NUCAPS-derived near-surface lapse rate and vapor pressure deficit, mid-troposphere moisture content, and instability parameters to facilitate early warning of pyroCb development. NRL-MMD is developing fire pixel clustering and NUCAPS filtering techniques to focus on specific wildfire events that are likely to produce pyroCb activity. The overarching objective is to provide weather forecasters and firefighting agencies with a potentially invaluable resource related to hazards ensuing from convective cloud development over active wildfires.

Alaska Spring River Breakup

Speakers: Celine van Breukelen (Alaska-Pacific River Forecast Center) and Rick Thoman (Alaska Center for Climate Assessment and Policy) There’s a deep snowpack across Alaska as spring melt approaches. Celine van…
