As yet, the reason is not known, but analyses of time - dependent regional comparisons suggest that it is associated with a tendency towards loss of «spring» growth response (Briffa et al., 1 999b) and, at least for subarctic Siberia, it may be connected with changes in the timing of spring snowmelt (Vaganov et al., 1999).
