BACKGROUND Patterns of concerted fluctuation in populations-synchrony-can reveal impacts of climatic variability on disease dynamics. We examined whether malaria transmission has been synchronous in an area with a common rainfall regime and sensitive to the Indian Ocean Dipole (IOD), a global climatic phenomenon affecting weather patterns in East Africa. METHODS We studied malaria synchrony i...

the tele-connection patterns are the major constituents of climate at global and regional scale(s). the karoon basin is of a vital stance in providing natural water supply and hydroelectric; this basin is facing major fluctuations in rainfall regime. identifying the effect of tele-connection on great karoon basin rainfall regime is the subject of this study. to accomplish this objective the sea...

A framework for short-term probabilistic forecasting of watershed flood stage conditions using a distributed rainfall-runoff model is proposed. A stochastic rainfall pattern simulation model capable of generating input for a distributed rainfall-runoff model is developed. Generation of rainfall patterns over a 6-hour period is achieved using a translation vector rainfall forecasting process mod...

In this paper we use farmers' actual experiences with changes in rainfall levels and theirresponses to these changes to assess if patterns of fertilizer use are responsive tochanges in rainfall patterns. Using plot and farm level panel data from the centralHighlands of Ethiopia matched with corresponding village level rainfall data; resultsshow that both the current year’s d...

This chapter also focusesaddresses on precipitation intensity measurements (in particular rate of rainfall or rainfall intensity) due to their rapidly increased need for the interpretation of rainfall patterns, rainfall event modeling and forecasts, everyday meteorological and engineering applications, the investigation of evolving events at the local to regional scale with potential tremendous...

The Madden-Julian Oscillation (MJO) is a tropical atmospheric phenomenon, associated with periods of active convection in the eastern hemisphere tropics.The MJOs temporal scale (22-90 days) coincides with a gap between weather (synoptic forecasts out to 10 days) and climate (seasonal and longer forecasts).Analysis of 35 years of daily rainfall data shows significant modulation of tropical and e...
