Analysis of Forecastability of Rapid Growth Periods of Alaska Wildfires in both Boreal and Tundra Ecosystems
The Hollings Scholars utilized an existing database of daily wildfire acreage back to at least the 1990s. They identified sub-monthly periods of rapid wildfire growth in both boreal and tundra ecosystems and performed analysis of associated atmospheric conditions and synoptic weather patterns using online and UAF available meteorological reanalysis data. This presentation will present the findings of their work.

VAWS: CIRA Development of Alaska-Relevant Satellite Applications from Suomi-NPP/JPSS-1 and GOES-R
The Cooperative Institute for Research in the Atmosphere (CIRA), established at Colorado State University in 1980, works closely with NOAA to develop algorithms and applications based on its cadre of environmental satellites. Here, we present some of these applications, including the science behind them, with an eye toward their relevance to the Alaska Region.

VAWS: Volcanic Cloud Monitoring in the North Pacific: The Dawning of the GOES-R Era
Volcanic clouds, which are a major aviation hazard, are complex and the background environment in which they reside is often complicated as well. Much of the complexity is due to the multi-composition nature of volcanic clouds, which frequently consist of some combination of volcanic ash, volcanic gases, and hydrometeors. Thus, volcanic cloud remote sensing is very challenging.

River Ice Breakup: What Do We Know?
This presentation will focus on mechanical river ice breakup and the historical evolution of our understanding of this topic. The presentation will include discussions of ice cover formation and the typical resulting ice structure, wave-ice interaction, the physics of the cracking, and the current status of our understanding of breakup.

Understanding the Arctic Through A Co-Production of Knowledge
The Arctic is changing at an accelerated rate due to climate change and increased anthropogenic activity. Given the rate of change, never has it been more important to work toward a holistic understanding of the Arctic’s interconnecting systems.

VAWS: An Exploration of Kodiak Wind Events
In this presentation, the factors leading to this strong wind event will be explored in-depth. In addition, a climatology of the top 10 wind events to occur in Kodiak City will be presented and classified based on similar synoptic and mountain wave properties. Finally, a statistical gap wind tool has been developed to help forecasters anticipate wind events which will be shared.

VAWS: Integrating Polar-Orbiting Products into the Forecast Routine for Explosive Cyclogenesis & Extratropical Transition
This presentation seeks to show some early analysis and potential uses of the polar-orbiting datasets to compliment the geostationary imagery and therefore lead to earlier identification and possible warnings.
-
-
VAWS: Diagnosis and Validation of Surface Precipitation Type
In this talk, several issues related to surface hydrometeor classification are discussed. These include uncertainty in the observations, algorithms used to deduce the precipitation type from numerical weather prediction models, and the uncertainty in the models themselves.

Do Trophic Cascades Affect The Storage and Flux of Atmospheric Carbon? An Analysis for Sea Otters and Kelp Forests
We combined data collected over the last 40 years to estimate the indirect effects of sea otters on ecosystem carbon production and storage across their North American range from Vancouver Island to the western edge of the Aleutian Islands. We find that sea otters, by suppressing sea urchins, substantially increase kelp ecosystem productivity and have a strong influence on kelp carbon flux and storage.
