Conveners of the following four sessions invite presentations from the
Arctic community:
Session 8043: Wildfire in a changing world: Interactions with climate
and ecosystems
Conveners: Yuhang Wang, Hanqin Tian, Xiaohong Liu, Yongqiang Liu
Increasing observational and modeling evidence show that wildfire has
been changing around the globe since preindustrial times as a result of
climate change and human activities. For example, extreme large
wildfires in regions such Indonesia are major public health concerns. In
the western United States in recent decades, wildfire has steadily
increased with a drying environment and taken an ever-larger toll on the
local economy. In this session, the conveners encourage studies that
improve the modeling and measurement capabilities and make use of these
capabilities to investigate physical and chemical processes that
elucidate wildfire interactions with regional and global climate,
ecosystems, and air quality.

and Disturbance Regimes in Arctic and Sub-Arctic Regions
Conveners: Syndonia Bret-Harte, Jeff White Merritt Turetsky, Tom Douglas
High latitude ecosystems are undergoing rapid change as climate warms
and alters disturbance regimes, particularly wildfire, permafrost thaw
and insect outbreaks. Our understanding of ecosystem responses to these
changes is complicated by strong feedbacks between biota and
biogeochemical cycling. Remote sensing, change detection, and
chronosequence studies are used to study ecosystem function under
current and historical disturbance regimes. These approaches often vary
between upland, wetland, and lake systems. Across all systems, patterns
of interannual and seasonal variation are key knowledge gaps. This is
particularly challenging for identifying trajectories of change across
the landscape. Presentations are invited using remote sensing, long-term
studies, or process-level experiments to improve our understanding of
changes in ecosystem structure and function, for example variations in
carbon and nutrient cycling, in the north. This session will enable
synergies and future collaborations of researchers working across
terrestrial and aquatic arctic systems at multiple spatial and temporal
scales. Invited Presenters: Rob Striegl, Sally MacIntyre, Ruth Varner,
and Miriam Jones.
https://agu.confex.com/agu/fm15/preliminaryview.cgi/Session8597Session 8785: Remote sensing of northern high-latitude ecosystem and
landscape change
Conveners: Daniel Hayes, Guido Grosse, Benjamin Jones, Andrew Parsekian
Terrestrial and aquatic ecosystems across the northern high-latitudes
are undergoing rapid, extensive, and unprecedented changes in their
nature, structure, and function. Remote sensing is a critical tool for
monitoring these changes, providing key data and techniques for scaling
in situ measurements, parameterizing and evaluating mechanistic models,
and testing hypotheses on dynamic ecological and landscape processes.
This session seeks contributions describing the state-of-the-art in new
data collections and analysis to quantify and characterize climate- and
disturbance- driven change indicators across arctic and boreal
landscapes. Conveners invite contributions that use remote sensing
information from multi-scale platforms, i.e. ground, aircraft, and
satellites, to observe and quantify these dynamics and contribute to an
improved understanding of the drivers and consequences of ecosystem and
landscape change. Contributions that demonstrate the use of remote
sensing data products in modeling and decision support and/or the
challenges and future opportunities for remote sensing in high latitudes
are encouraged.
https://agu.confex.com/agu/fm15/preliminaryview.cgi/Session8785Session 7605: Extratropical and High-latitude Storms,
Teleconnections, Extreme Weather, and the Changing Polar Climate
Conveners: Xiangdong Zhang, Kent Moore, Xiaojun Yuan, Qinghua Ding
Synoptic storms and large-scale teleconnections are prominent features
characterizing daily-to-decadal climate variability in the extratropics
and high latitudes. Storms often bring extreme weather, including
high-wind events, large ocean waves and surges, coastal flooding and
erosion, as well as rapid temperature changes. Teleconnection patterns
play modulating roles in storm activity, linking polar and midlatitude
climate. In addition, the tropics has been recognized as an important
source for triggering teleconnections, and may also be subject to
impacts of polar climate changes. Storms and teleconnections have
demonstrated systematic variations, leading to alterations of feedback
processes and, in turn, contributing to climate variability and change.
This session will provide a venue to present progress and new ideas on
extratropical and high-latitude storm activity, tropical or
extratropical teleconnections with the polar regions, and associated
physical feedback processes in the context of the changing polar
climate, as well as resulting extreme weather events, ecosystem- and
societal impacts.
