RISA Practical Guide to Wavelet Analysis
Publisher: American Meteorological Society
Abstract: A practical step-by-step guide to wavelet analysis is given, with examples taken from time series of the El Niño?Southern Oscillation (ENSO). The guide includes a comparison to the windowed Fourier transform, the choice ...

Removing ENSO-Related Variations from the Climate Record
Publisher: American Meteorological Society
Abstract: An important question in assessing twentieth-century climate change is to what extent have ENSO-related variations contributed to the observed trends. Isolating such contributions is challenging for several reasons, including ...
Storm Track Predictability on Seasonal and Decadal Scales
Publisher: American Meteorological Society
Abstract: This paper is concerned with estimating the predictable variation of extratropical daily weather statistics (?storm tracks?) associated with global sea surface temperature (SST) changes on interannual to interdecadal scales, ...
Web-Based Reanalysis Intercomparison Tools (WRIT) for Analysis and Comparison of Reanalyses and Other Datasets
Publisher: American Meteorological Society
Abstract: ospheric reanalysis datasets are widely used in climate science, many technical issues hinder comparing them to each other and to observations. The reanalysis fields are stored in diverse file architectures, data formats, ...
Feasibility of a 100-Year Reanalysis Using Only Surface Pressure Data
Publisher: American Meteorological Society
Abstract: Climate variability and global change studies are increasingly focused on understanding and predicting regional changes of daily weather statistics. Assessing the evidence for such variations over the last 100 yr requires ...
A Comparison of Variational and Ensemble-Based Data Assimilation Systems for Reanalysis of Sparse Observations
Publisher: American Meteorological Society
Abstract: An observing system experiment, simulating a surface-only observing network representative of the 1930s, is carried out with three- and four-dimensional variational data assimilation systems (3D-VAR and 4D-VAR) and an ...
ENSO-Forced Variability of the Pacific Decadal Oscillation
Publisher: American Meteorological Society
Abstract: Variability of the Pacific decadal oscillation (PDO), on both interannual and decadal timescales, is well modeled as the sum of direct forcing by El Niño?Southern Oscillation (ENSO), the ?reemergence? of North Pacific sea ...
Changes of Probability Associated with El Niño
Publisher: American Meteorological Society
Abstract: Away from the tropical Pacific Ocean, an ENSO event is associated with relatively minor changes of the probability distributions of atmospheric variables. It is nonetheless important to estimate the changes accurately for ...
Changes of Subseasonal Variability Associated with El Niño
Publisher: American Meteorological Society
Abstract: This paper is concerned with assessing the impact of the El Niño?Southern Oscillation (ENSO) on atmospheric variability on synoptic, intraseasonal, monthly, and seasonal timescales. Global reanalysis data as well as ...
