Statistical Interpolation Using Cyclostationary EOFs
Publisher: American Meteorological Society
Abstract: Investigated here is the space?time estimation or statistical interpolation of a global variable based on a few observations. Estimation of a global data field is essentially a problem of optimally estimating spherical ...
Statistical Prediction of Cyclostationary Processes
Publisher: American Meteorological Society
Abstract: Considered in this study is a cyclostationary generalization of an EOF-based prediction method. While linear statistical prediction methods are typically optimal in the sense that prediction error variance is minimal within ...
On the Evolution of the Annual Cycle in the Tropical Pacific
Publisher: American Meteorological Society
Abstract: Extraction of the accurate annual cycle in the tropical Pacific sea surface temperature field is addressed as a demonstration of the utility of a new technique called the cyclostationary empirical orthogonal function (CSEOF) ...
Optimal Detection Using Cyclostationary EOFs
Publisher: American Meteorological Society
Abstract: Many climatic and geophysical processes are cyclostationary and exhibit appreciable cyclic (monthly, daily, etc.) variation of their statistics in addition to interannual fluctuations. Utilization of this nested variation ...
A Comparison Study of EOF Techniques: Analysis of Nonstationary Data with Periodic Statistics
Publisher: American Meteorological Society
Abstract: Identification of independent physical/dynamical modes and corresponding principal component time series is an important aspect of climate studies for they serve as a tool for detecting and predicting climate changes. While ...

Regional Simulations of Greenhouse Warming Including Natural Variability
Publisher: American Meteorological Society
Abstract: The perception of the hypothesized greenhouse effect will differ dramatically depending upon the location on the earth at which the effect is analyzed. This is due mainly to two causes: 1) the warming signal depends upon ...
Detection of Forced Climate Signals. Part II: Simulation Results
Publisher: American Meteorological Society
Abstract: This paper considers some tests of the procedures suggested in Part I on the detection of forced climate signals embedded in natural variability. The optimal filters are constructed from simulations of signals and natural ...
EOF-Based Linear Prediction Algorithm: Theory
Publisher: American Meteorological Society
Abstract: This study considers the theory of a general three-dimensional (space and time) statistical prediction/extrapolation algorithm. The predictor is in the form of a linear data filter. The prediction kernel is based on the ...
The Response Time of the Temperature of the Equatorial Troposphere to ENSO Heating
Publisher: American Meteorological Society
Abstract: Air temperature anomalies, averaged over the troposphere to 200 mb and around the earth from 10°S to 10°N, lag the similarly averaged El Niño?Southern Oscillation (ENSO) atmospheric latent heating anomalies by about one ...
