HFIP Annual Review Meeting

Each year, the Hurricane Forecast Improvement Program has a review meeting. The emphasis this year will include reports from each of the HFIP teams and a session to discuss the HFIP real-time system—results from this summer and plans for next. The real-time system next summer is planned as a major demonstration of what can be accomplished in hurricane forecast guidance given sufficient computer resources and so needs to be carefully planned. Computing resources next summer may be approximately twice that available this summer.

HFIP Regional GSI-Hybrid Data Assimilation Workshop

The HFIP Regional GSI-Hybrid Data Assimilation Workshop is part of the effort of the DTC to build a unified GSI-hybrid community system and helping accelerate transitions from research to operations on such a system. Specifically, the purposes of this workshop (tentatively) include:

  • Collect information and assess ongoing hybrid related research
  • Facilitate discussion on building a GSI-hybrid framework
  • Work with HFIP management to focus HFIP research community on a single regional hybrid system for hurricane forecast operations.

The workshop will host invited speakers. We are open to proposals for lectures and talks. More information will be sent out later.

2:30pm Targeted discussion Summary of the presentations (Brian) and requirements (Vijay)

• How would our collaboration be?
o What is the current system? How to work based on it? How many
contributors are we expecting? What are the EMC requirements?
Community requirements?
• How can we manage the collaboration and monitor the progress?
• Who will make decisions? A committee? What procedure to follow?
• What development work needs to be done in the short term to make
the GSI-hybrid system a viable alternative for those folks to run next
o GSI system – EMC baseline, how to let others build on it?
o Ensemble system – EMC baseline, how to let others build on it?
o Hybrid system- What are the common parts to be generalized?
How to do it? By whom? How to incorporate community
contributions (especially those using different packages)
o How to test the system and incorporate contributions from
• Testing metrics
• Distributed testing or centered
o Milestones/deliverables – goals realistic? Computational resources?
Timeline? POCs?
• How will the development of the GSI-hybrid system interact with
development of the existing system(s), e.g., GSI.
4:15pm Summary and steps towards formalizing the plan A list of requirements, and a development and testing plan (timeline,
POCs, etc)
