Testing and Improving ENSO Models by Process Using Transfer Functions
(Wiley-Blackwell, 2010)
Some key elements of ENSO are not consistently well captured in GCMs. However, modifying the wrong parameters may lead to the right result for the wrong reason. We introduce “transfer functions” to quantify the input/ ...
The Effect of Milankovitch Variations in Insolation on Equatorial Seasonality
(American Meteorological Society, 2010)
Although the sun crosses the equator 2 times per year at the equinoxes, at times in the past the equatorial insolation has had only one maximum and one minimum throughout the seasonal cycle because of Milankovitch orbital ...
The Role of Ocean Dynamics in the Optimal Growth of Tropical SST Anomalies
(American Meteorological Society, 2010)
The role of ocean dynamics in optimally exciting interannual variability of tropical sea surface temperature (SST) anomalies is investigated using an idealized-geometry ocean general circulation model. Initial temperature ...
Nonnormal Frontal Dynamics
(American Meteorological Society, 2010)
The generalized stability of the secondary atmospheric circulation over strong SST fronts is studied using a hydrostatic, Boussinesq, two-dimensional f-plane model. It is shown that even in a parameter regime in which these ...
Correlations between Fine Particulate Matter \((PM_{2.5})\) and Meteorological Variables in the United States: Implications for the Sensitivity of \(PM_{2.5}\) to Climate Change
(Elsevier, 2010)
We applied a multiple linear regression (MLR) model to study the correlations of total \(PM_{2.5}\) and its components with meteorological variables using an 11-year (1998–2008) observational record over the contiguous US. ...
Chemistry of Hydrogen Oxide Radicals \((HO_x)\) in the Arctic Troposphere in Spring
(European Geosciences Union, 2010)
We use observations from the April 2008 NASA ARCTAS aircraft campaign to the North American Arctic, interpreted with a global 3-D chemical transport model (GEOS-Chem), to better understand the sources and cycling of hydrogen ...
Intercomparison Methods for Satellite Measurements of Atmospheric Composition: Application to Tropospheric Ozone from TES and OMI
(European Geosciences Union, 2010)
We analyze the theoretical basis of three different methods to validate and intercompare satellite measurements of atmospheric composition, and apply them to tropospheric ozone retrievals from the Tropospheric Emission ...
The Signature of an Unbalanced Earthquake Cycle in Himalayan Topography?
(Geological Society of America, 2010)
Fifty percent of the relative motion between the Indian and Asian plates is accommodated by active convergence at the Himalayan Range Front (HRF). Earthquake cycle processes on shallowly dipping HRF thrust faults generate ...
Geobiology of the Late Paleoproterozoic Duck Creek Formation, Western Australia
(Elsevier, 2010)
The ca. 1.8 Ga Duck Creek Formation, Western Australia, preserves 1000 m of carbonates and minor iron formation that accumulated along a late Paleoproterozoic ocean margin. Two upward-deepening stratigraphic packages are ...
A Bayesian Algorithm for Reconstructing Climate Anomalies in Space and Time. Part 1: Development and Applications to Paleoclimate Reconstruction Problems
(American Meteorological Society, 2010)
Reconstructing the spatial pattern of a climate field through time from a dataset of overlapping instrumental and climate proxy time series is a nontrivial statistical problem. The need to transform the proxy observations ...
