Importance of latent heat release in ascending air streams for atmospheric blocking

Atmospheric blocking can contribute to extreme weather events. A Lagrangian approach applied to reanalysis data shows that a large fraction of air masses are heated before entering a blocking system, pointing to a role for latent heating. Atmospheric blocking is a key component of extratropical weather variability1 and can contribute to various types of extreme weather events2,3,4,5. Changes in blocking frequencies due to Arctic amplification...
