säänvaihteluilta
Säänvaihteluilta is a Finnish term that describes the period of fluctuating weather that often occurs in late autumn. It signifies a transition from the more stable, cold conditions of early autumn to the harsher, more consistently wintry weather of late November and December. During säänvaihteluilta, temperatures can be highly variable, with periods of freezing temperatures alternating with milder spells that can lead to thawing. This instability can result in a range of weather phenomena, including rain, sleet, snow, and freezing rain.
The ground may become alternately frozen and thawed, affecting soil conditions and potentially impacting vegetation. Ice
