Final Report on Workshop
Frank Marks' Report on Workshop

Foreword

This volume contains most of the Keynote presentations and Topic Chair and Rapporteurs reports for the fifth International Workshop on Tropical Cyclones (IWTC-V). The keynote session on Present and Future Satellite Observations for Tropical Cyclone Research and Forecasting includes various forecast office present uses and needs, some near-term applications, and future satellite systems. The Topics include: (1) Structure and structure change including intensity change; (2) Tropical cyclone-related precipitation; (3) Tropical Cyclone Motion; (4) Tropical cyclone formation and extratropical transition; and (5) Tropical cyclone impacts. The two primary purposes of the Topic reports are to summarize progress since IWTC-IV and to make recommendations for the IWTC-V participants to consider.


My thanks especially go to the Topic Chairs and Rapporteurs for preparing these reports. Where possible, the Rapporteurs solicited inputs from Working Group members and sought comments on early drafts of the reports. Clearly, the Internet has been an essential communication link in the preparation of these reports.


I believe this volume will do much to ensure the success of IWTC-V in planning for the future.

Director, IWTC-V
