NGGPS Atmospheric Physics Workshop | Presentations

Tuesday, November 8, 2016

8:30 am Workshop Welcome (Fred Toepfer, Bill Lapenta, Vijay Tallapragada) - Workshop goals and priorities of physics team plan Scientifically-based Working Group Session (Chairs: Shrinivas Moorthi/Jim Doyle) (50 min per SWG - 20 min presentation + 30 min discussion)

Presentations should provide an overview of NGGPS priorities for each SWG and planned physics testing, aligned activities/timelines/deliverables (both funded and/or unfunded/proposed as applicable), and identify any major gaps and opportunities.

8:45 am Convection and Boundary Layer (Jongil Han, Chris Bretherton)

9:35 am Cloud Microphysics (Ruiyu Sun, Jian-Wen Bao)

10:25 am Coffee Break

10:45 am Radiation (Yu-Tai Hou, Robert Pincus)

11:35 am Gravity Wave and Large-Scale Orographic (and non-Orographic) Drag (Jordan Alpert, Steve Eckermann)

12:25 pm Lunch

1:25 pm Earth System Surface Fluxes (EMC: Mike Ek, Fei Chen) Related Topics Session (Chair: Jimy Dudhia)

Presentations should provide an overview of the subject with an emphasis on the SWG interest areas, and identify relevant gaps and opportunities for testing and development, particularly for the NGGPS project.

2:15 pm Stochastic Physics (Phil Pegion, Yuejian Zhu)

2:45 pm Aerosol interactions w/ physics (Georg Grell, Paul Ginoux) 3:15 pm Coffee Break

3:45 pm Wrap-up session (Lead: Jim Doyle) - Recap of earlier discussions, identify key gaps in the physics team plan and any new development underway within the broader community that might address these gaps.

Wrap up by 5:00 pm Optional group dinner

12:30 pm Instructions for break-out groups and grab lunches

12:45 pm Break-out groups by SWG - Defining priorities for advancing competing physics schemes

Topics to discuss:

• How do we determine the most promising parameterization scheme(s) that can be delivered by 2019 for potential implementation into operations? What are the next steps and priorities?
• How do we ensure the advanced physics options support NWS’s unified modeling goals for all applications (global weather, ensemble, seasonal climate, convective scale, hurricanes, etc.).
• What set of metrics should be used to evaluate physics packages?
• What procedure(s) should be used for identifying advantages of different approaches?
• What tests/diagnostics are needed for physics evaluations and to evaluate the fidelity of the interactions between schemes?
• What tools and data sets do developers need for their development and testing?

Focus areas and leads:

• Convection, Boundary Layer and Gravity Wave Drag (Shrinivas Moorthi and Valery Yudin)
• Clouds and Radiation (Brad Ferrier and Sarah Lu)
• Earth System Surface Fluxes (Helin Wei) 2:45 pm Coffee Break

3:00 pm Break-out group reporting (Chair: Jimy Dudhia) 10-min summaries from each break-out group followed by discussion
