Backward seasons, droughts and other bioclimatic indicators of


Phenoclimatic fluctuations, biorhythms and agricultural patterns are
intricately linked to the local meteorological conditions, and over time
to the climate of a region. Many of these patterns were captured in the
daily journal entries of diarists in the New England states of Vermont and
New Hampshire in the pre-digital era. This presentation will highlight the
documentary data available from these states in the 1680-1900 time period. Special attention will be given to analyzing backward season
characteristics and the concomitant influences on frost occurrences, sugar maple production and the onset of drought. Finally, the creation of an indicator-based drought index to enable spatio-temporal comparisons will be presented.


Refreshments will be served at 3:30pm
