Summary
This chapter presents a synopsis of some of the latest developments in our understanding of pyroconvective interactions, their links to fire geometrym and their role in driving dynamic fire behavior and extreme wildfire development. We highlight the need to augment traditional quasi-steady wildfire modeling paradigms with more sophisticated approaches that combine highly-instrumented, larger-scale experimental studies with state-of-the-art computational modeling. We identify the need to take maximum advantage of technical advances in remote sensing technology to provide new ways of observing extreme fire events.
