The video discusses numerical weather prediction (NWP), a method of forecasting weather using computer simulations. Presenters Alan Halley and Colin Clancy explain the process, including the use of ensemble prediction systems to account for uncertainties like the butterfly effect. The history of weather forecasting is covered, highlighting advancements in computing power. The video also explores the vast data volumes used in NWP and its applications in public safety and various sectors. Impact-based forecasting is emphasized, focusing on how weather affects people rather than just numerical values.
