Tropical Cyclone Product Updates at UW-CIMSS for 2026 Tony Wimmers, Derrick Herndon, Sarah Griffin , Tim Olander , Jeff Hawkins Much has been gained in understanding and forecasting of tropical cyclones over the past half century, aided by increased observational technologies, computational power, and research advances. This chapter overviews the fundamentals and some frontiers in the science of tropical cyclones. It now becomes more user-friendly.

Key Insights

I hope this e-book and its PDF version, together with other publications on tropical cyclones, will become a valuable source of information, tools, data, techniques, methodologies, and best practices in tropical cyclone monitoring, forecasting and warning services.
