Record #126720:

Methodological aspects on river cryophenology exemplified by a tricentennial break-up time series from Tornio / Juha Kajander.

Title: Methodological aspects on river cryophenology exemplified by a tricentennial break-up time series from Tornio / Juha Kajander.
Author(s): Kajander, Juha.
Date: 1993.
In: Geophysica. (1993.), Vol. 29(1-2) (1993)
Abstract: Cryophenological observations have been used as climatological indicators. Longest records are for ice in rivers. As case-study, series of 300 years is examined. By using several sources, errors can be detected and homogeneity improved. Tornio series begins during Maunder minimum. Break-up now occurs on average 13 days earlier than 300 years ago. Temperatures are available for last 134 years. Break-up has excellent correlation with mean temperatures of April and May.
