Atmospheric jet stream variability reflects vegetation activity in Europe

Jet streams are a key component of the climate system, whose dynamics couple closely to regional variability. Yet, link between jet stream variability and vegetation activity has received little attention. Here, we leverage our understanding mid-latitude over Euro-Atlantic sector probe climate–vegetation interactions across Europe. We indices related meridional location large-scale zonal wind speed with remotely-sensed greenness anomalies during locally-defined growing seasons. Correlations latitude point control stream's on large parts This potential is mediated by anomalies’ correlations temperature, soil moisture downward surface solar radiation.

Furthermore, modulates conditions at onset end season. not only specific zone, but also landclass subperiod within It thus important use season for interpreting atmospheric controls phenology. Results consistent correlation analysis emerge when focussing local high or low months anomalies, confirming relevance activity.
