Oblique Gravity Wave Propagation During Sudden Stratospheric Warmings
;
; ; (Journal of Geophysical Research: Atmospheres, 2020)
Gravity waves (GWs) are important for coupling the mesosphere to the lower atmosphere during sudden stratospheric warmings (SSWs). Here, a minor SSW is internally generated in a simulation with the upper-atmosphere ... -

Drought poses significant challenges to global water security in a warming world. A global‐scale synthesis of the multivariate drought risk considering interdependencies between drought attributes across disparate climate ... -
Observations and high-resolution simulations of convective precipitation organization over the tropical Atlantic
; ; (Quarterly Journal of the Royal Meteorological Society, 2020)
High-resolution simulations (grid spacing 2.5 km) are performed with ICON-LEM to characterize convective organization in the Tropics during August 2016 over a large domain ranging from northeastern South America, along the ... -
Observations of Gravity Wave Refraction and Its Causes and Consequences
; ; ; ; ; ; ; ; ; ; (Journal of Geophysical Research: Atmospheres, 2023-02-06)
Horizontal gravity wave (GW) refraction was observed around the Andes and Drake Passage during the SouthTRAC campaign. GWs interact with the background wind through refraction and dissipation. This interaction helps to ... -
Observed and Simulated Variability of Droplet Spectral Dispersion in Convective Clouds Over the Amazon
; ; ; ; ; ; ; ; ; ; ; (Journal of Geophysical Research: Atmospheres, 2021-10-15)
In this study, the variability of the spectral dispersion of droplet size distributions (DSDs) in convective clouds is investigated. Analyses are based on aircraft measurements of growing cumuli near the Amazon basin, and ... -
Observed Subdecadal Variations of European Summer Temperatures
Müller, W.A.;; Ghosh, R. (Geophysical Research Letters, 2020)
We identify subdecadal variations in European summer temperatures in coupled and uncoupled century-long reanalyses. Spectral analyses reveal significant peaks at 5–10 years in the midtwentieth century. The subdecadal ... -
Observing Earth’s magnetic environment with the GRACE-FO mission
; ; ; ; ; ; ; (Earth, Planets and Space, 2021-02-15)
The Gravity Recovery and Climate Experiment Follow-On (GRACE-FO) mission carries magnetometers that are dedicated to enhance the satellite’s navigation. After appropriate calibration and characterisation of artificial ... -
Observing noctilucent clouds
(Internat. Assoc. of Geomagnetism & Aeronomy, 2006)This manual and instruction book was written by a group of active researchers, both professional and amateur. There are chapters giving practical advice for taking visual observations, photographing the clouds with film ... -
Ocean Bottom Pressure Variability: Can It Be Reliably Modeled?
Androsov, Alexey; Boebel, Olaf;; ; Macrander, Andreas; (Journal of Geophysical Research: Oceans, 2020)
Ocean bottom pressure (OBP) variability serves as a proxy of ocean mass variability, the knowledge of which is needed in geophysical applications. The question of how well it can be modeled by the present general ocean ... -
Ocean Model Formulation Influences Transient Climate Response
; ; ; ; ; ; (Journal of Geophysical Research: Oceans, 2021-12-05)
The transient climate response (TCR) is 20% higher in the Alfred Wegener Institute Climate Model (AWI‐CM) compared to the Max Planck Institute Earth System Model (MPI‐ESM) whereas the equilibrium climate sensitivity (ECS) ... -
On classification of logging data

On gravity wave parameterisation in vicinity of low‐level blocking
(Atmospheric Science Letters, 2022-03-07)
This note is framed as an open question to the community regarding parameterisation schemes using the blocking layer depth to reduce the orographic gravity wave drag. It is the purpose of this note to argue that the current ... -
On intrinsic uncertainties in earth system modelling
(Univ. Potsdam, 2006)Various types of uncertainty plague climate change simulation, which is, in turn, a crucialelement of Earth System modelling. This fact was recognized for example in the Third Assessment Report (TAR) of the Intergovernmental ... -
On the determination of the atmospheric outer scale length of turbulence using GPS phase difference observations: the Seewinkel network
; (Earth, Planets and Space, 2020-12-04)
Microwave electromagnetic signals from the Global Navigation Satellite System (GNSS) are affected by their travel through the atmosphere: the troposphere, a non-dispersive medium, has an especial impact on the measurements. ... -
On the Dynamical Importance of Gravity Wave Sources Distributed Over Different Heights in the Atmosphere
; ; (Journal of Geophysical Research: Space Physics, 2023-03-15)
Gravity waves (GWs) are generated at all altitudes in the atmosphere, but sources above the lower stratosphere are rarely considered by parameterizations employed in general circulation models. This study assesses the ... -
