Abstract: In this study, the nature and causes for observed regional precipitation trends during 1977?2006 are diagnosed. It is found that major features of regional trends in annual precipitation during 1977?2006 are consistent ...

Abstract: Assessing climate-related societal vulnerability and mitigating impacts requires timely diagnosis of the nature of regional hydrologic change. A late-twentieth-century emergent trend is discovered toward increasing ...

Abstract: Inhomogeneity in gridded meteorological data may arise from the inclusion of inhomogeneous station data or from aspects of the gridding procedure itself. However, the homogeneity of gridded datasets is rarely questioned, ...

Abstract: AbstractAlthough the link between droughts and heat waves is widely recognized, how climate change affects this link remains uncertain. Here we assess how, and by how much, human-induced climate change affects summertime ...

Abstract: The spatial patterns, time history, and seasonality of African rainfall trends since 1950 are found to be deducible from the atmosphere?s response to the known variations of global sea surface temperatures (SSTs). The ...

Abstract: The long-term mean date of the monsoon onset over Kerala (MOK) varies between 30 May and 2 June according to different estimates, with a standard deviation of 8?9 days. The earliest date of MOK, and the most delayed one, ...

Abstract: AbstractFactors responsible for extreme monthly rainfall over Texas and Oklahoma during May 2015 are assessed. The event had a return period of at least 400 years, in contrast to the prior record, which was roughly a 100-yr ...

Abstract: AbstractTwo theories for observed East Africa drying trends during March?May 1979?2013 are reconciled. Both hypothesize that variations in tropical sea surface temperatures (SSTs) caused East Africa drying. The first invokes ...
