Abstract The subtropical free troposphere plays a critical role in the radiative balance of the Earth. However, the complex interactions controlling moisture in this sensitive region and, in particular, the relative importance of long‐range transpo

Weather extremes are often associated with atmospheric blocking, but how the underlying physical processes leading to blocking respond to climate change is not yet fully understood. Here we track blocks as upper-level negative potential vorticity (PV

The mechanisms underlying the occurrence of temperature extremes in Iberia are analysed considering a Lagrangian perspective of the atmospheric flow, using 6-hourly ERA-Interim reanalysis data for the years 1979–2012. Daily 2-m minimum temperatures

This study investigates the meteorological conditions in Europe during summer 2007 (June-August) and their representativity compared to climatology, based upon (re-)analysis data from the European Centre for Medium-range Weather Forecasts (ECMWF) for

Much of our understanding of atmospheric circulation comes from relationships between aspects of the circulation and the mean state of the atmosphere. In particular, the concept of mean available potential energy (MAPE) has been used previously to re

Extratropical cyclone airstreams, such as warm conveyor belts (WCBs), are linked to strong precipitation along with latent heat release at low levels and, thus, changes in the low-level PV distribution. Previous studies have shown significant changes

Extreme precipitation events cause major ecological and societal hazards (e.g. river flooding and landslides). Aggravatingly, climate change will likely exacerbate extreme precipitation events on a global scale. Scientifically even more concerning, h

Despite the high confidence in the overall intensification of extreme precipitation at global scale in response to warming, uncertainties in regional intensity and spatial distribution remain large. Changes due to thermodynamical processes are largel

Historical extreme flooding events in central European river catchments caused high socioeconomic impacts. Previous studies have analysed single events in detail but have not focused on a robust analysis of the underlying extreme precipitation events

Stable water isotope observations have the potential to provide information on cloud processes in the trade-wind region, in particular when combined with high-resolution model simulations. In order to evaluate this potential, nested convection-resolv
