Review of1st Workshop
AndCurrent Goals
11-13 April 20112nd IBTrACS Workshop 2
Used for many industries:◦ Building codes for coastal zones◦ Risk assessment◦ Insurance loss analysis◦ Climate change research
Needed for locating TCs in satellite data (e.g., HURSAT)
Complete record of pressure and wind needed.
Many basins have more than one source of data
No single one-stop-shop for a global data set existed
11-13 April 20112nd IBTrACS Workshop 3
11-13 April 20112nd IBTrACS Workshop 4
International◦ Many nations and agencies working together
Best Track◦ Information on tropical cyclones◦ Enormous impact on life and property worldwide
Archive◦ One-stop-shop
Climate◦ Global distribution◦ Cyclone intensity◦ Temporal variability
Stewardship◦ Maintaining data for future generations
11-13 April 20112nd IBTrACS Workshop 5

First ever international meeting to specifically discuss best track data?
5-7 May 2009 - Participants worldwide Topics
◦ Operational Best tracking procedures◦ Wind-pressure relationships◦ Wind speed conversions◦ Global Reanalysis◦ IBTrACS improvements
Meeting summary in AMS BAMS
11-13 April 20112nd IBTrACS Workshop 10
Recommendations◦ To IBTrACS team◦ To forecast agencies (that make best track data)◦ To the WMO
Collaboration◦ Growing collaboration on BT issues amongst
participants
11-13 April 20112nd IBTrACS Workshop 11
11-13 April 20112nd IBTrACS Workshop 12
The IBTrACS team should…◦ Document BT procedures,
Work with agencies Through a survey
◦ Provide all parameters as provided by original agency in IBTrACS
◦ Distribute official and unofficial datasets of other TC related data
◦ Archive all ancillary data◦ Get involved with the IWTC
11-13 April 20112nd IBTrACS Workshop 13
Best tracking agencies should …◦ Report more parameters and use WMO format
◦ Document current and historic BT practices
◦ Standardize definitions of winds and wind conversions
◦ Rescue and archive documents relevant to BT data
◦ “Best track” throughout life cycle (through ET)
◦ Encourage best track data discussions at IWTCHeld IBTrACS special focus session in La Reunion
Held IBTrACS special focus session in La Reunion
Accomplished by TCM through recognition of Harper report
Many have worked with IBTrACS on the community survey
11-13 April 20112nd IBTrACS Workshop 14
Endorse and/or formally adopt as global archive to aid RSMCs and
TCWCs
Recommend improvements and enhancements
Collaborate with IBTrACS on improvements
Standardize and document best tracking procedures
Cooperate on survey of operational procedures
11-13 April 20112nd IBTrACS Workshop 15
11-13 April 20112nd IBTrACS Workshop 16
To continue the momentum of international collaboration by bringing together representatives from IBTrACS data providers, IBTrACS users and other TC researchers.
In addition, the workshop aims to address unresolved issues regarding construction, archive and use of best track data.
11-13 April 20112nd IBTrACS Workshop 17
Need◦ Much relies on quality of best track data
Approach◦ Make producers aware of impact of poor BT data
on weather and climate◦ Make users aware of known BT issues and/or
limitations
11-13 April 20112nd IBTrACS Workshop 18
Need◦ No assessment of BT data is available◦ No better authors than the data producers◦ No better time than the present
Approach◦ Co-authors from Workshop participants/agencies◦ Identify and catalog current and historic practices
where appropriate◦ Assess dataset quality and use
11-13 April 20112nd IBTrACS Workshop 19
11-13 April 20112nd IBTrACS Workshop 20
Need◦ Formalize the structure of IBTrACS◦ International direction and feedback on plans
Approach◦ Enact the BT committee
