[CRYOLIST] 4 upcoming ACCAP webinars

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@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.

Cheers,

Tina

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 at:

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: https://accap.uaf.edu/VAWS_April2018


2. April 2018 National Weather Service Alaska Climate Outlook Briefing
Rick Thoman, Climate Science and Services Manager, National Weather Service
Friday, 27 April 2018
12-1:00pm  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 (https://accap.uaf.edu/April_2018)

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?
Steven F. Daly PE, PhD, D.WRE ERDC/CRREL USACE
Tuesday, 1 May 2018
10-11:00am  AKDT

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

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 breakup.

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

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 at:

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.    

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