Abstract

A 20-year record from an eastern North American phenological network is used to demonstrate a regional scale approach to plant-climate interaction studies. Models incorporating first leaf emergence and surface weather data are described and tested. Results show that a small percentage of synoptic events, marked by warm air advection, account for the majority of high energy accumulation totals. Some of these events serve as ''capstones'' to the energy accumulation in the week before first leaf. The model incorporating the ''capstone effect'' is best at predicting the arrival of the spring green wave, with a mean absolute error of 6.59 days
