Geomagnetic field declination: from decadal to centennial scales

Ocean–Atmosphere Interactions on Interannual to Decadal Time Scales

Temperature Responses to Spectral Solar Variability on Decadal Time Scales

[1] Two scenarios of spectral solar forcing, namely Spectral Irradiance Monitor (SIM)‐based out‐of‐phase variations and conventional in‐phase variations, are input to a time‐dependent radiative‐convective model (RCM), and to the GISS modelE. Both scenarios and models give maximum temperature responses in the upper stratosphere, decreasing to the surface. Upper stratospheric peak‐to‐ peak respon...

Orbital tuning of geomagnetic polarity time-scales

Milankovitch climate cyclicity and magnetic polarity stratigraphy are being successfully combined as a powerful geochronometer in the astronomical polarity timescale (APTS). The APTS for 0–5.23 Ma has been rapidly accepted as the definitive chronology for the Pliocene and Pleistocene against which even high precision radiometric dating is now calibrated. Extensions of astronomical calibration t...

Dendrogeomorphically derived slope response to decadal and centennial scale climate variability: Black Mesa, Arizona, USA

A major impediment to an understanding of the links between climate and landscape change, has been the relatively coarse resolution of landscape response measures (rates of weathering, sediment production, erosion and transport) relative to the higher resolution of the climatic signal (precipitation and temperature on hourly to annual time scales). A combination of high temporal and spatial res...

Characterizing decadal to centennial variability in the equatorial Pacific during the last millennium

[1] The magnitude of sea surface temperature variability in the NINO3.4 region of the equatorial Pacific on decadal and longer timescales is assessed in observational data, state-of-the-art (Coupled Model Intercomparison Project 5) climate model simulations, and a new ensemble of paleoclimate reconstructions. On decadal to multidecadal timescales, variability in these records is consistent with...
