Meeting Report

Workshop Proceedings                                                           

To improve theunderstanding and prediction of rainfall associated with landfalling tropical cyclones.

Basic Research: To enhance the understanding of some key physical processes influencing the characteristics of tropical cyclone precipitation. To investigate what elements modulate the features of landfalling tropical cyclone rainfall, how they solely and/or jointly influence the rainfall characteristics and which are the dominant factors.

Applied Research: To develop an optimal configuration of state-of-the-art numerical models suitable for simulating and forecasting tropical cyclone rainfall. To develop new statistical and dynamical methods of predicting rainfall in landfalling tropincal cyclones and improve the performance of operational numerical models.
