Insolation and Greenhouse Gas Forcing of the South American Monsoon System Across Three Glacial-Interglacial Cycles
(
- Geophysical Research Letters
, 2020)
Precipitation extremes with devastating socioeconomic consequences within the South American Monsoon System (SAMS) are expected to become more frequent in the near future. The complexity in SAMS behavior, however, poses ...
Evaluation and application of GPS and altimetry data over central Dronning Maud Land, Antarctica
(Univ. Bremen, 2009)
The polar ice sheets are unique paleoclimatic archives and play an important role in recent and future climate. The melting of the big freshwater reservoirs will not only increase the global sea level, but will also influence ...
Reconstruction of the Basin‐Wide Sea‐Level Variability in the North Sea Using Coastal Data and Generative Adversarial Networks
(
- Journal of Geophysical Research: Oceans
, 2020-12-03)
We present an application of generative adversarial networks (GANs) to reconstruct the sea level of the North Sea using a limited amount of data from tidal gauges (TGs). The application of this technique, which learns how ...
An application of WKBJ theory for triad interactions of internal gravity waves in varying background flows
(
- Quarterly Journal of the Royal Meteorological Society
, 2021-01-22)
Motivated by the question of whether and how wave–wave interactions should be implemented into atmospheric gravity‐wave parametrizations, the modulation of triadic gravity‐wave interactions by a slowly varying and vertically ...
Quasi‐10‐Day Wave and Semidiurnal Tide Nonlinear Interactions During the Southern Hemispheric SSW 2019 Observed in the Northern Hemispheric Mesosphere
(
- Geophysical Research Letters
, 2020-11-26)
Mesospheric winds from three longitudinal sectors at 65°N and 54°N latitude are combined to diagnose the zonal wave numbers (m) of spectral wave signatures during the Southern Hemisphere sudden stratospheric warming (SSW) ...
Extension of the plasma radiation database PARADE for the analysis of meteor spectra
(
- Meteoritics & Planetary Science
, 2021-02-03)
The advancement in the acquisition of spectral data from meteors, as well as the capability to analyze meteoritic entries in ground testing facilities, requires the assessment of the performance of software tools for the ...
Detection Limits and Near-Field Ground Motions of Fast and Slow Earthquakes
(
- Journal of Geophysical Research: Solid Earth
, 2020)
We investigate theoretical limits to detection of fast and slow seismic events, and spatial variations of ground motion expected from M 6 earthquakes at short epicentral distances. The analyses are based on synthetic ...
September 2019 Antarctic Sudden Stratospheric Warming: Quasi-6-Day Wave Burst and Ionospheric Effects
(
- Geophysical Research Letters
, 2020)
An exceptionally strong stationary planetary wave with Zonal Wavenumber 1 led to a sudden stratospheric warming (SSW) in the Southern Hemisphere in September 2019. Ionospheric data from European Space Agency's Swarm satellite ...
Trends in AOD, Clouds, and Cloud Radiative Effects in Satellite Data and CMIP5 and CMIP6 Model Simulations Over Aerosol Source Regions
(
- Geophysical Research Letters
, 2020)
Several regions worldwide have seen significant trends in anthropogenic aerosol emissions during the period of detailed satellite observations since 2001. Over Europe (EUR) and North America (NAM) there were strong declines, ...
Comparing the Properties of ICME-Induced Forbush Decreases at Earth and Mars
(
- Journal of Geophysical Research: Space Physics
, 2020)
Forbush decreases (FDs), which are short-term drops in the flux of galactic cosmic rays, are caused by the shielding from strong and/or turbulent magnetic structures in the solar wind, especially interplanetary coronal ...
