ABSTRACT:
A reconstruction of spring (April-May) temperature for northern
Fennoscandia developed from the Tornionjoki (Tornio river) long
cryophenological record of ice break-up dates, back to AD 1693,
is presented. The record is strongly climatically sensitive
and explains 67% of the variance in the instrumental data over
the last 150 years. The record exhibits a stepped decrease in
the duration of the river's ice cover by 14 days, equivalent to
an increase in April-May mean temperature of approximately 2.5°C
over the last three centuries. The relationship between the date
of ice break-up, and accumulated daily mean temperatures (>0°C)
is investigated. Uncertainty in the observation of ice break-up
is also considered in addition to the potential of this time
series for regional climate model validation.
