Short description

Summer high-temperature extreme (SHTE) in Scandinavia is generally associated with persistent anticyclonic circulation patterns. Another factor leading to or enhancing SHTE is soil moisture deficit which causes drought and can change surface energy balance and near surface temperature. While recent warming over the northern hemisphere has positively contributed to terrestrial vegetation growth through increase of photosynthesis and extension of photosynthetic growing season in general, SHTE and drought can have a sizable genitive impact on forest growth. However, how SHTE and drought in Sweden have changed over the last decades and how these changes have influenced Swedish forest growth remain largely unclear. This project aims to fill in this knowledge gap.
