Introduction

This website of the World Meteorological Organization (WMO) is aimed to serve as a platform for the information sources for tropical cyclone forecasters to obtain data and tools which are useful for monitoring and forecasting of tropical cyclones. Forecasters may access the various sources providing conventional and specialized data/products including those from numerical predictions and remote sensing observations as well as forecasting tools concerning tropical cyclone development, motion, intensification and wind distribution. It will continue to develop along with the availability of new data and products and will also contain techniques and best practices from tropical cyclone forecast centers that could be adapted by other forecast centers.

Weather Event Discussion

Tropical-Storms is an international email discussion group for subscription by those who are professionally active in either the research or forecasting of tropical storms worldwide. It helps foster communication between the research and forecasting communities.

Details of the Tropical-Storms mailing are available here.

TC Cases: Difficult and extreme cases

This list provides examples of difficult forecasting and extreme events from operational TC agencies.

A recommendation from the eighth International Workshop on Tropical Cyclones (IWTC-VIII; Korea, 2014) stated that operational TC centers identify their most difficult forecast cases as well as extreme events and make them available to the TC community. The TC research community is encouraged to use this list to focus on model performance and explore the predictability of these events. A selection of difficult cases (2015-2018) was presented at IWTC-IX in 2018 which formed the starting point of this list with the intention for ongoing sharing by operational agencies to the TC community.

To add new cases (administrator login here), please contact relevant agencies in different basins.
