Central equatorial Africa is deficient in long-term, ground-based measurements of rainfall; therefore, the aim of this study is to assess the accuracy of three high-resolution, satellite-based rainfall products in western Uganda for the 2001–10 period. The three products are African Rainfall Climatology, version 2 (ARC2); African Rainfall Estimation Algorithm, version 2 (RFE2); and 3B42 from th...

In this study a new conceptual model for partial duration series analysis was applied to determine the likely rainfall of the monsoon season and the pattern of rainfall events distribution. Example case study was carried out with rainfall data of semiarid area, Agra, India, experiencing extremes of yearly rainfall; ranging between high (1200 mm) to low (300 mm). The coefficient values for the e...

BACKGROUND Sudden unexpected death in epilepsy (SUDEP) represents the main cause of death in patients with refractory epilepsy. No evidence-based intervention to prevent SUDEP exists. We postulated that pooling data from randomised placebo-controlled trials in patients with refractory epilepsy might show a lower incidence of SUDEP in patients receiving antiepileptic drugs (AEDs) at efficacious ...

Following a predicted decline in water resources in the Mediterranean Basin, we used reaction-diffusion equations to gain a better understanding of expected changes in properties of vegetation patterns that evolve along the rainfall transition between semi-arid and arid rainfall regions. Two types of scenarios were investigated: the first, a discrete scenario, where the potential consequences o...

Design flood estimation is often required in engineering practice such as design of hydrologic structures, flood plain management, river ecological studies and flood insurance studies. The national guideline for design flood estimation in Australia known as Australian Rainfall and Runoff (ARR) recommends the Design Event Approach as the preferred method of rainfallbased design flood estimation ...

The accurate production of a rainfall environment similar to natural rainfall by a rainfall simulator (RS) is a crucial and challenging task in rainfall instrument testing or calibration. Although the spatial uniformity of rainfall accumulation is a key parameter of an RS, the spatial uniformity comparison between simulated rainfall and natural rainfall, and the spatial uniformity improvements ...

[1] This study addressed the diurnal cycle of rainfall during the summer monsoon season (May to September) around the Indochina peninsula, with a focus on the diurnal cycle’s relationship to terrain. The investigation used 10 year (1998–2007) Tropical Rainfall Measuring Mission Precipitation Radar (TRMM‐PR) observations. Results revealed that the diurnal variations in rainfall over the Indochin...

Miguel, Satyanath, and Sergenti (2004) argue that lower rainfall levels and negative rainfall shocks increase conflict risk in Sub-Saharan Africa. This conclusion rests on their finding of a negative correlation between conflict in t and rainfall growth between t-1 and t-2. I argue that this finding is driven by a positive correlation between conflict in t and rainfall levels in t-2. If lower r...
