WRF-based dynamical downscaling over High Mountain Asia
… climate simulations for the present day and the mid-Pliocene ( ∼ 3 Ma) were dynamically downscaled to 30 km grid spacing over HMA, using the same model configuration as the HAR v2. By keeping land surface conditions the same in both downscaling experiments, this study was able to isolate the …

Regional dynamical downscaling and analysis of water balance across different regions and time scales
… water balance sensitivity to present-day and mid-Pliocene climate regimes, were examined, demonstrating the potential of RDD in paleoclimatic research. Downscaling of GCM data, to a resolution of 30 km, enabled us to investigate the regional drivers of the basin's water balance, including the …

Paleomagnetic data bearing on the evolution of the Walker Lane Belt transfer zone from mid-Miocene to present : an investigation of the inferred southern and eastern boundaries
… Belt (WLB) transfer zone, which initiated in the mid-Miocene, presently links the Eastern California Shear Zone in the south to the Central Nevada Seismic Belt and northern WLB to the northeast and north, respectively. The boundaries of the transfer system are clear on the northern and western …

The Dynamics of the Late Neogene Antarctic Ice Sheets in the Central Ross Sea using a Multianalytical Approach
… ice. Above Ross Sea Unconformity 3, early to mid Pliocene samples show a shift back to West Antarctic provenance with abundant Cretaceous zircons and more radiogenic neodymium values. Late Pliocene to Pleistocene samples, deposited above Ross Sea Unconformity 2, reflect dominant East Antarctic …

Pollen and grain size records in abyssal sediments of the northwest Pacific Ocean as proxies of Plio-Pleistocene climate change /
… composition ofterrigenous flux to the western mid-latitude North Pacific and its relation to climate change in East Asia since the mid-Pliocene. Dust-sized particles (including pollen), sourced from the arid regions and loess plateaus in East Asia are entrained by prevailing westerly winds and …

Improved Understanding of The 2018 Mw7.5 Palu Earthquake Using Local Earthquake Tomography and Numerical Ground Motion Simulation
… from magmatic activity as recent as the mid-Pliocene, and 3) Low velocity areas in the south of Palu Valley coincident with identified strong geothermal signatures in the uppermost crust. The results show that these structures correlate with the fault rupture of the 2018 earthquake and …

LATE MIOCENE AND PLIOCENE PALEOCEANOGRAPHY OF THE LOW LATITUDE NORTHERN HEMISPHERE AND ITS IMPLICATIONS FOR FUTURE CLIMATE CHANGE
… North Equatorial Counter Current. During the mid-Piacenzian warm period (MPWP; ~3.3-3.0 Ma), SST in the Panama Basin was ~0.8°C cooler than today, while the subtropical NWA was only ~1.1°C warmer. This corroborates evidence for reduced meridional SST gradients during the mid-Pliocene as well …

Characteristics and evolution of a dynamic prograding continental margin: the late Neogene Giant Foresets Formation, northern Taranaki Basin, New Zealand
The Pliocene-Pleistocene Giant Foresets Formation represents the progradation and development of the modem continental margin in northern Taranaki Basin. The dynamic evolution of this formation is fundamentally linked to a Pliocene-Pleistocene increase in sediment flux sourced from South Island, to …
