Abstract: Ethiopian agriculture and Nile River flows are heavily dependent upon the Kiremt season (June?September) precipitation in the upper Blue Nile basin, as a means of rain-fed irrigation and streamflow contribution, respectively. ...

Abstract: There has been an apparent increase in the frequency and duration of El Niño?Southern Oscillation events in the last two decades relative to the prior period of record. Furthermore, 1990?95 was the longest period of sustained ...

Abstract: patial and temporal variability of relative humidity over the West African monsoon (WAM) region is investigated. In particular, the variability during the onset and retreat periods of the monsoon is considered. A K-means ...

Abstract: Dominant spatiotemporal patterns of joint sea surface temperature (SST) and sea level pressure (SLP) variability in the Atlantic Ocean are identified using a multivariate frequency domain analysis. Five significant frequency ...

Abstract: Guided by the increasing awareness and detectability of spatiotemporally organized climatic variability at interannual and longer timescales, the authors motivate the paradigm of a climate system that exhibits excitations ...

Abstract: A Bayesian methodology is used to assess the information content of categorical, probabilistic forecasts of specific variables derived from a general circulation model (GCM) forecast ensemble, and to combine a ?prior? ...

Abstract: Dominant modes of individual and joint variability in global sea surface temperatures (SST) and global Palmer drought severity index (PDSI) values for the twentieth century are identified through a multivariate frequency ...

Abstract: n analysis of annual hydroclimatic variability in the Upper Colorado River basin (UCRB) for the period of 1906?2006 was performed to understand the dominant modes of multidecadal variability. First, wavelet-based spectral ...

Abstract: Analyses of streamflow, snow mass temperature, and precipitation in snowmelt-dominated river basins in the western United States indicate an advance in the timing of peak spring season flows over the past 50 years. Warm ...

Abstract: Summer monsoon rains are a critical factor in Thailand?s water resources and agricultural planning and management. In fact, they have a significant impact on the country?s economic health. Consequently, understanding the ...
