The influence of DACCIWA radiosonde data on the quality of ECMWF analyses and forecasts over southern West Africa
(
- Quarterly Journal of the Royal Meteorological Society
, 2020)
During the DACCIWA (Dynamics–Aerosol–Chemistry–Cloud Interactions in West Africa) field campaign ∼900 radiosondes were launched from 12 stations in southern West Africa from 15 June to 31 July 2016. Subsequently, data-denial ...
Following moist intrusions into the Arctic using SHEBA observations in a Lagrangian perspective
(
- Quarterly Journal of the Royal Meteorological Society
, 2020)
Warm and moist air masses are transported into the Arctic from lower latitudes throughout the year. Especially in winter, such moist intrusions (MIs) can trigger cloud formation and surface warming. While a typical cloudy ...
Untersuchung der Partikel-Lagrangeschen Advektionsmethode anhand von meteorologisch relevanten Beispielen
(Univ. Frankfurt (Main), 2001)
Diese Arbeit beschreibt Entwürfe zur Anwendung einer nicht-interpolierenden Advektionsmethode in numerischen Wettervorhersagemodellen. Es wird an verschiedenen Beispielen dargestellt, in welcher Weise eine solche ...
Impact of Intraseasonal Waves on Angolan Warm and Cold Events
(
- Journal of Geophysical Research: Oceans
, 2021-04-28)
The intraseasonal variability of the tropical eastern boundary upwelling region in the Atlantic Ocean is investigated using multiyear mooring and satellite data. Pronounced oscillations of alongshore velocity and sea level ...
How Dynamic Boundary Conditions Induce Solute Trapping and Quasi-stagnant Zones in Laboratory Experiments Comprising Unsaturated Heterogeneous Porous Media
(
- Water Resources Research
, 2019)
The vadose zone is subject to dynamic boundary conditions in the form of infiltration and evaporation. A better understanding of implications for flow and solute transport, arising from these dynamic boundary conditions ...
Assimilating visible satellite images for convective-scale numerical weather prediction: A case-study
(
- Quarterly Journal of the Royal Meteorological Society
, 2020)
Satellite images in the visible spectral range contain high-resolution cloud information, but have not been assimilated directly before. This paper presents a case-study on the assimilation of visible Meteosat SEVIRI images ...
Untersuchung der Photooxidantien Wasserstoffperoxid, Methylhydroperoxid und Formaldehyd in der Troposphäre der Antarktis
(Univ. Bremen, 2001)
Photooxidants play an important role for the oxidation capacity of the troposphere. The presented work deals with seasonal changes of atmospheric photooxidants like hydrogen peroxide (H2O2), methylhydroperoxide (MHP) and ...
A new algorithm to retrieve the sea ice concentration using weather-corrected 85 GHz SSM/I measurements
(Univ. Bremen, 2001)
Sea ice is a very important component of the climate system. While the Arctic sea ice extent has retreated during the past 20 years, it has remained constant in the Antarctic. In order to better understand the role of sea ...
Using seasonal rainfall clusters to explain the interannual variability of the rain belt over the Greater Horn of Africa
(
- International Journal of Climatology
, 2020)
The seasonal cycle of rainfall over the Greater Horn of Africa (GHA) is dominated by the latitudinal migration and activity of the tropical rain belt (TRB). The TRB exhibits high interannual variability in the GHA and the ...
