Avohakkuualueen supan lämpoolojen vaikutus puunkasvuun Lammin Kilparistillä (The impact of the microclimate on tree growth in a kettle hole in a deforested area in Lammi, southern Finland)
On clear nights with little or no wind strong outgoing radiation causes cold air to flow down the slopes and rapidly fill the deepest part of the kettle hole. In the cold nights at the beginning of the growth period, frost affected the lowest
branches of the spruces growing in the lower parts of the kettle hole, and smaller trees were totally frozen. Tree growth increased in the upper slopes of the kettle hole, where the trees have survived the radiation shock following the deforestation.
