RISWavelet Analysis of Variability, Teleconnectivity, and Predictability of the September–November East African Rainfall
Publisher: American Meteorological Society
Abstract: By applying wavelet analysis and wavelet principal component analysis (WPCA) to individual wavelet-scale power and scale-averaged wavelet power, homogeneous zones of rainfall variability and predictability were objectively ...
Nonstationary Analysis of Annual Maximum Streamflow of Canada
Publisher: American Meteorological Society
Abstract: oth natural climate change and anthropogenic impacts may cause nonstationarities in hydrological extremes. In this study, long-term annual maximum streamflow (AMS) records from 145 stations over Canada were used to investigate ...
Wavelet Analysis of Seasonal Rainfall Variability of the Upper Blue Nile Basin, Its Teleconnection to Global Sea Surface Temperature, and Its Forecasting by an Artificial Neural Network
Publisher: American Meteorological Society
Abstract: ainfall is the primary driver of basin hydrologic processes. This article examines a recently developed rainfall predictive tool that combines wavelet principal component analysis (WPCA), an artificial neural networks-genetic ...
Spatiotemporal Changes in Precipitation Extremes over Canada and Their Teleconnections to Large-Scale Climate Patterns
Publisher: American Meteorological Society
Abstract: In the past few decades, there have been more extreme climate events occurring worldwide, including Canada, which has also suffered from many extreme precipitation events. In this paper, trend analysis, probability ...
Wavelet Analysis on the Variability, Teleconnectivity, and Predictability of the Seasonal Rainfall of Taiwan
Publisher: American Meteorological Society
Abstract: Using wavelet analysis, the variability and oscillations of November?January (NDJ) and January?March (JFM) rainfall (1974?2006) of Taiwan and seasonal sea surface temperature (SST) of the Pacific Ocean were analyzed. From ...
Prediction of East African Seasonal Rainfall Using Simplex Canonical Correlation Analysis
Publisher: American Meteorological Society
Abstract: A linear statistical model, canonical correlation analysis (CCA), was driven by the Nelder?Mead simplex optimization algorithm (called CCA-NMS) to predict the standardized seasonal rainfall totals of East Africa at 3-month ...
