Planning
Workshop for the THORPEX Pacific Asian Regional Campaign (T-PARC), Tropical
Cycle Structure (TCS-08) and Other Collaborative Experiments
Princeville Resort, Kauai
4-6 December 2007
4 December 2007:

8:30 am 8:45 am Welcome, opening remarks, and meeting logistics: David Parsons and Pam Johnson
Overview of the Scientific Motivation and
Observational Facility Contributions for T-PARC:
The talks in these sessions are meant to provide a flow of information from those involved in planning the experiment to the participants. The talks will describe the scientific and societal motivation for the experiment in participating countries and the aircraft, sounding, ship and other major observational facilities that these nations will provide. The talks are intended to be concise and not delve deeply into the scientific issues or flight plans, but function to provide everyone with a common background for more detailed scientific and facility discussions later in the meeting. These talks are not intended to be personal research, but representative of the broad goals of national efforts.

Collaborative
Experiments:
A number of experiments are planned to occur within a similar time frame as T-PARC. Some are closely connected to T-PARC in their experimental design and others are simply two-way opportunities for collaboration. The talks will describe the scientific and societal motivation for the experiment and the observational facilities. The talks are intended to provide everyone with a common background for more detailed scientific and facility discussions later in the meeting.

Science and Strawplans
for Experimental Design:
Session chairs: David Raymond and Kevin Cheung
These presentations on
some of the primary scientific topics of interest to the experiment are
intended to delve deeper into the scientific issues and propose straw plans for
observational (flight track, soundings, satellite ops) and modeling strategies
to meet these scientific goals. The two presenters for each topic are
challenged to come up with a single presentation and encouraging input from
other researchers to present a consensus viewpoint, and with some consideration
of competing options, rather than their own research ideas. The presenters are
expected to have an integrated view that includes all relevant airborne,
sounding, ship and satellite measurements, plus some preliminary views on the
relevance of operational and research modeling. Be concise and allow time for
discussion.

8:30 am Continental Breakfast
8:30 am 8:45 Charge to Working Groups
David Parsons and Pat Harr
Develop an concise description of your scientific
objectives
What platforms and/or instruments (both exp. And opr)
are required for your research?
How will these facilities be used (flight tracks, freq of the deployment
of sondes,
Launching of driftsondes in clusters, etc)?
What are your plans for modeling and impact studies? Real
time or retrospective?
What needs to you you for operational and/or
special products?
How will you interact with the other components of T-PARC and with the
collaborative experiments?
Experimental Design:
The charge to the
working groups is to begin the organization of the materials required for an
operations plan. For example, such a major field experiment with multiple
aircraft will require an operations plan that contains a series of preselected
flight plans that can be adapted to the specific goals of an aircraft mission.
The desired operations for dropsondes from the research aircraft and driftsonde
should be outlined as well as radiosondes from ships and ground-based stations.
The working group discussions can contain short presentations by individual
scientists on their scientific reasoning for the operational scenarios. The
general intent, however, is to produce a few consensus scenarios on operations
where possible rather than a large list.
Each group is assigned a
leader and a rapporteur. At the end of the day, the leader and rapporteur will present a summary of the group discussion
to the plenary session. These summaries
will identify the primary objectives, the assets critical to each objective,
plans for utilization of the assets, and potential problems.

temptation to make a presentation so that the time can be reserved for
discussion.
