Forecasting Green-up: It’s seems simple…but it’s not

Speaker: Rick Thoman, ACCAP

Green-up, that time when leaves burst forth from Alaska’s deciduous trees has important implications for the seasonal ecology, society and even meteorology in the state. Fairbanks has a unique record of more than four decades of green-up dates. This presentation builds on work started more than 20 years ago to demonstrate how this unique observational record combined with the latest advances in weather and climate forecasting, allow for an objective forecast for the timing of green-up well before the snow has even started to melt.
