Does an Intrinsic Source Generate a Shared Low-Frequency Signature in Earth’s Climate and Rotation Rate?
Publisher: American Meteorological Society
Abstract: revious studies have shown strong negative correlation between multidecadal signatures in length of day (LOD)?an inverse measure of Earth?s rotational rate?and various climate indices. Mechanisms remain elusive. Climate ...
Intraseasonal Variability in a Two-Layer Model and Observations
Publisher: American Meteorological Society
Abstract: A two-layer shallow-water model with R15 truncation and topographic forcing is used to study intraseasonal variability in the Northern Hemisphere?s (NH?s) extratropical atmosphere. The model?s variability is dominated by ...
Air Temperature and Anthropogenic Forcing: Insights from the Solid Earth
Publisher: American Meteorological Society
Abstract: Earth?s rotation rate [i.e., length of day (LOD)], the angular momentum of the core (CAM), and surface air temperature (SAT) all have decadal variability. Previous investigators have found that the LOD fluctuations are ...
Atmospheric Contributions to Earth Nutation: Geodetic Constraints and Limitations of the Torque Approach
Publisher: American Meteorological Society
Abstract: Atmospheric motions in the retrograde diurnal (S1) band are of interest to a wide community of researchers in earth dynamics and geodesy, due to their potential contribution to the low-frequency motions of the rotation ...
