Long term variations of atmospheric synoptic variability: A study based on radiosonde data from Lindenberg (Germany)

open access: yesMeteorologische Zeitschrift, 1995
In an extension of a study by Fraedrich et al. (1979a, b) we show how the atmospheric processes generating a local climate state can vary from year to year and between two decades in Eastern Germany - an area which is frequently visited by mature ...

Estimation of Geopotential Value W0 for the Geoid and Local Vertical Datum Parameters

open access: yesRemote Sensing, 2023
Unification of the global vertical datum has been a key problem to be solved for geodesy over a long period, and the main challenge for unifying the global vertical datum system is to determine the geopotential value W0 of the geoid and to calculate the ...

Evaluation of Geopotential Height at 500 hpa with Rainfall Events: A Case Study of Iraq

open access: yesAl-Mustansiriyah Journal of Science, 2022
The geopotential height at 500 hPa is a key factor in determining the weather and climate conditions around the world. This paper aims to study the effect of 500hpa geopotential height in Iraq weather from a synoptic perspective and evaluation the ...

Global Glacial Isostatic Adjustment Constrained by GPS Measurements: Spherical Harmonic Analyses of Uplifts and Geopotential Variations

open access: yesRemote Sensing, 2020
In addition to studies of sea level change and mantle rheology, reliable Glacial Isostatic Adjustment (GIA) models are necessary as a background model to correct the widely used Gravity Recovery and Climate Experiment (GRACE) monthly gravity solutions to

January ozone anomaly over the North Atlantic-European region: Longitude-dependent decadal change in total ozone during 1979-1992

open access: yesMeteorologische Zeitschrift, 1996
A large decrease in total ozone of up to more than 4 DU/yr occurred over Europe during January 1979-1992. This value is almost twice that of the zonal mean.

Analysis of a Relative Offset between the North American and the Global Vertical Datum in Gravity Potential Space

open access: yesRemote Sensing, 2023
The accurate estimation of the zero-height geopotential level in a local vertical datum (LVD) is critical for linking traditional height reference systems to a global height system.

Past evolution of western Europe large-scale circulation and link to precipitation trend in the northern French Alps [PDF]

open access: yesWeather and Climate Dynamics, 2022
Detecting trends in regional large-scale circulation (LSC) is an important challenge as LSC is a key driver of local weather conditions. In this work, we investigate the past evolution of western Europe LSC based on the 500 hPa geopotential height fields
