The Lithospheric Structure of the Saharan Metacraton From 3-D Integrated Geophysical-Petrological Modeling
(
- Journal of Geophysical Research: Solid Earth
, 2020)
We modeled crustal and lithospheric thickness variation as well as the variations in temperature, composition, S wave seismic velocity, and density of the lithosphere beneath the Saharan Metacraton (SMC) applying an ...
Auroral Arcs: The Fracture Theory Revisited
(
- Journal of Geophysical Research: Space Physics
, 2021-01-15)
The fracture theory for auroral arcs, developed by the author since 1980, compares the decoupling of the magnetic field from the ionosphere by the auroral acceleration region (AAR) with the breaking of a solid rod. In the ...
Stable Isotope Composition of Cyclone Mekunu Rainfall, Southern Oman
(
- Water Resources Research
, 2020-12-14)
Cyclone Mekunu hit the southern Arabian Peninsula in late May 2018 and brought rainfall amounts that accounted for up to 6 times the mean annual precipitation. Coming from the Arabian Sea, a quite underdocumented region ...
Numerical impacts on tracer transport: A proposed intercomparison test of Atmospheric General Circulation Models
(
- Quarterly Journal of the Royal Meteorological Society
, 2020-09-07)
The transport of trace gases by the atmospheric circulation plays an important role in the climate system and its response to external forcing. Transport presents a challenge for Atmospheric General Circulation Models ...
Formation and maintenance of subsiding shells around non‐precipitating and precipitating cumulus clouds
(
- Quarterly Journal of the Royal Meteorological Society
, 2020-12-10)
A shell of subsiding air is generally known to develop around cumulus clouds and shield them from their environment. We seek here to improve our understanding of such shells by (a) revealing the detailed vertical and ...
Quantifying Convective Aggregation Using the Tropical Moist Margin's Length
(
- Journal of Advances in Modeling Earth Systems
, 2020)
On small scales, the tropical atmosphere tends to be either moist or very dry. This defines two states that, on large scales, are separated by a sharp margin, well identified by the antimode of the bimodal tropical column ...
Climate change impacts on agriculture's southern frontier – Perspectives for farming in North Patagonia
(
- International Journal of Climatology
, 2020)
Winter chill is expected to decrease in many of the suitable growing regions for deciduous trees. Argentinean North Patagonia hosts extensive fruit tree cultivation, which provides an important contribution to both local ...
The Impact of Wettability and Surface Roughness on Fluid Displacement and Capillary Trapping in 2-D and 3-D Porous Media: 2. Combined Effect of Wettability, Surface Roughness, and Pore Space Structure on Trapping Efficiency in Sand Packs and Micromodels
(
- Water Resources Research
, 2020)
A comprehensive understanding of the combined effects of surface roughness and wettability on the dynamics of the trapping process is lacking. This can be primarily attributed to the contradictory experimental and numerical ...
A Spectrally Consistent Globally Defined Geodetic Mean Dynamic Ocean Topography
(
- Journal of Geophysical Research: Oceans
, 2020)
The space-borne geodetic temporal mean dynamic topography (MDT) is obtained from the difference of altimetric mean sea surface (MSS) h and the geoid height N. With the geostrophic surface currents obtained from its gradient, ...
Novel Quantification of Shallow Sediment Compaction by GPS Interferometric Reflectometry and Implications for Flood Susceptibility
(
- Geophysical Research Letters
, 2020)
Estimates of flood susceptibility and land loss in the world's coastal regions depend on our knowledge of sea level rise (SLR) from increases in ocean mass and volume, as well as knowledge of vertical land motion. Conventional ...
