Middle Miocene tectonic boundary conditions for use in climate models

Simulation of the Middle Miocene Climate Optimum

[1] Proxy data constraining land and ocean surface paleotemperatures indicate that the Middle Miocene Climate Optimum (MMCO), a global warming event at 15 Ma, had a global annual mean surface temperature of 18.4 C, about 3 C higher than present and equivalent to the warming predicted for the next century. We apply the latest National Center for Atmospheric Research (NCAR) Community Atmosphere M...

Surface Boundary Conditions for Mesoscale Regional Climate Models

This paper utilizes the best available quality data from multiple sources to develop consistent surface boundary conditions (SBCs) for mesoscale regional climate model (RCM) applications. The primary SBCs include 1) fields of soil characteristic (bedrock depth, and sand and clay * Corresponding author address: Dr. Xin-Zhong Liang, Illinois State Water Survey, University of Illinois at Urbana–Ch...

The Use of Boundary Conditions for Inductive Models

There is a large amount of interest in creating models from data using a variety of machine learning methods. Most of these approaches require a good distribution of observed values to produce reliable models. The use of background knowledge to augment the observed values has also been explored as a method to supplement the original feature set of training data. This paper argues that there is ...

The Oligocene–Miocene Boundary – Antarctic Climate Response to Orbital Forcing

Recent AU :2 high-resolution Oligocene–Miocene oxygen isotopic records revealed a relatively transient, ca. 2myr period, 1m amplitude cyclicity in isotopic values (Oi and Mi events, respectively). Intriguingly, it has been suggested that these isotopic excursions in oceanic dO were linked to ephemeral growth and decay in Antarctic ice sheets. A great deal of effort in the palaeoceanography comm...
