Hello All,

ACCAP has FOUR great webinars lined up in the next few weeks.  Hope you can
join us!

Do let me (Tina Buxbaum, tmbuxbaum at alaska.edu) know if you are interested
in hosting a satellite viewing site for any of the webinars.

I am also attaching a flyer for the May 1 webinar.




1. Virtual Alaska Weather Symposia Webinar: Alaska Hydrologic Conditions
going into Spring 2018
*Jessica Cherry, National Weather Service*
*Wednesday, 25 April 2018 *
*11:00am-12:00pm AKDT*

To register for the webinar, please follow the registration link available

This talk will provide a brief overview of current hydrologic conditions
and notable events over the past winter, including late freeze up on the
Kuskokwim, heavy snow in parts of the Interior, and drought in Southeast
Alaska. I will provide an outlook for breakup on the larger rivers this
spring and possible flood risks, as well as information about our daily
forecast products through breakup and during open water season.

Available in-person in *IARC/Akasofu 407 *on the UAF Campus or online

Registration and more information available at:

2. April 2018 National Weather Service Alaska Climate Outlook Briefing
*Rick Thoman, Climate Science and Services Manager, National Weather

*Friday, 27 April 201812-1:00pm  AKDT*

For more information, please go to: https://accap.uaf.edu/April_2018

Do you lie awake at nights wondering what the upcoming season will be like?
Want to place bets with friends and family on next month's weather? If so,
good news:

The tools and techniques for making monthly and season scale climate
forecasts are rapidly changing, with the potential to provide useful
forecasts at the month and longer range. Rick Thoman (Climate Science and
Services Manager, Environmental and Scientific Services Division, National
Weather Service Alaska Region) will review recent climate conditions around
Alaska, review forecast tools and finish up with the Climate Prediction
Center's forecast for the upcoming season.

Rick will also present a "*Feature-of-the-Month*" special addition in which
each month he will highlight a topic relevant to the particular month.

Available in-person in *IARC/Akasofu 407* on the UAF Campus or online (

Feel free to bring your lunch and join the gathering in-person or join
online to learn more about Alaska climate and weather.

This will be a monthly series generally taking place the third Friday of
each month.

3. Alaska Climate Webinar Series: River Ice Breakup: What Do We Know?

*Tuesday, 1 May 201810-11:00am  AKDT*

To register for the webinar, please follow the registration link available

Breakup transforms an ice-covered river into an open river. Two ideal forms
of breakup bracket the types of breakup that commonly occur. At one extreme
is thermal breakup. During an ideal thermal breakup, the river ice cover
deteriorates and melts in place, with no increase in flow and little or no
ice movement. At the other extreme is the more complex and less understood
mechanical breakup, which is the focus of this presentation. The main
driver of mechanical breakup is the flow discharge hydrograph. The increase
in flow induces stresses in the cover, and the stresses in turn cause
cracks and the ultimate fragmentation of the ice cover into pieces that are
carried by the channel flow. Ice jams take place at locations where the ice
fragments stop; severe and sudden hydraulic transients can result when
these ice jams form or when they release. This presentation will focus on
mechanical 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

4. Virtual Alaska Weather Symposia Webinar: New capabilities,
opportunities, and challenges using GOES-17 in Alaska
*Jordan Gerth, University of Wisconsin at Madison*
*Wednesday, 16 May 2018 *
*11:00am-12:00pm AKDT*

To register for the webinar, please follow the registration link available

Following a successful launch, the second new-generation Geostationary
Operational Environmental Satellite, GOES-S, became GOES-17 and is
currently in the test position of 89.5 degrees West longitude. This fall,
the satellite will begin drifting to its new position at 137 degrees West
longitude, where it will begin imaging as the operational GOES-West
satellite this November. GOES-West will dramatically improve weather
satellite imaging of Alaska, with four times more detail compared to
previous generation geostationary weather satellites, even on the North
Slope. This will enhance scientific studies and operational weather
monitoring of Alaska for nearly a decade to come. This presentation will
discuss the value of GOES-17, particularly the unique aspects and
challenges for high latitudes.
