Scaling of Eliassen‐Palm flux vectors
Atmospheric Science Letters, 2021 Eliassen‐Palm flux is one of the main diagnostics tools for wave propagation and wave‐mean flow interaction in atmospheric dynamics and in particular stratosphere‐troposphere coupling.

Stratosphere-troposphere coupling during stratospheric extremes in the 2022/23 winter
Weather and Climate Extremes, 2023 Using the ERA5 reanalysis, sea surface temperature, sea ice observations, and the real-time multivariate Madden-Julian Oscillation (MJO) index, the evolution of the stratospheric extreme circulation in the winter of 2022/2023 is explored.

Scaling turbulence drives the general circulation
Quarterly Journal of the Royal Meteorological Society, EarlyView.The NOAA Gulfstream SP4, which deployed the GPS dropsondes over the NE Pacific Ocean as part of the Winter Storms Project during the January–March periods of 2004, 2005 and 2006. Abstract Statistical multifractal analysis of airborne and dropsonde observations is used to show that persistence of velocity after molecular collisions breaks the continuous

The 1986–1989 ENSO cycle in a chemical climate model [PDF]
Atmospheric Chemistry and Physics, 2006 A pronounced ENSO cycle occurred from 1986 to 1989, accompanied by distinct dynamical and chemical anomalies in the global troposphere and stratosphere.

Quarterly Journal of the Royal Meteorological Society, EarlyView.The Weak‐Constraint Four‐Dimensional Variational (WC‐4DVAR) system markedly improved the analysis and forecasting of the 2024 sudden stratospheric warming (SSW) event. It reduced biases and enhanced 7–9 day predictions of temperature across the SSW life cycle, with the most pronounced gains for winds also during the critical onset period.

Quarterly Journal of the Royal Meteorological Society, EarlyView.Mediterranean tropical‐like cyclones show a clear seasonality, with September cyclones exhibiting the deepest convection and Ianos representing the most extreme case. While one or more dry intrusions are typically detected during the cyclone life cycle, Ianos instead features two much weaker descending airflows.

Asymmetry in the effect of North Atlantic sea surface temperature on the eddy‐driven jet
Quarterly Journal of the Royal Meteorological Society, EarlyView.Projections of climate over Europe and the Atlantic are uncertain due to the uncertainty surrounding future changes in North Atlantic sea surface temperatures (SSTs). Here, we demonstrate that warming in the North Atlantic Ocean is linked to a transition to a negative phase of the North Atlantic Oscillation, as well as to an equatorward displacement of

Quarterly Journal of the Royal Meteorological Society, EarlyView.This study investigates the thermodynamic and microphysical characteristics of updrafts and downdrafts of tropical deep convective anvil clouds using in situ measurements. We found that parts of the downdrafts are in ice supersaturation in these clouds.

Journal of Advances in Modeling Earth Systems, 2012 Extreme cold spells over Northern Europe during winter are examined in order to address the question to what degree and in which ways stratospheric dynamics may influence the state of the troposphere.
