“…A relatively small change in mean can lead to large changes in the frequency of extremes (Katz and Brown, 1992;Salinger and Griffiths, 2001). Globally, there has been a trend towards reduced numbers of frost and cold days and an increase in the number of hot days during the past century (Karl et al, 1999). Ireland's oceanic climate means that temperature extremes are rare, however, and, as a result, the mean air temperature fluctuates within quite narrow limits.…”

This paper presents an assessment of indicators of climate change in Ireland over the past century. Trends are examined in order to determine the magnitude and direction of ongoing climate change. Although detection of a trend is difficult due to the influence of the North Atlantic Ocean, it is concluded that Irish climate is following similar trajectories to those predicted by global climate models. Climatic variables investigated included the key temperature and precipitation data series from the Irish synoptic station network. Analysis of the Irish mean temperature records indicates an increase similar to global trends, particularly with reference to early-twentieth century wanning and, more importantly, rapid warming in the 1990s. Similarly, analysis of precipitation change support the findings of the United Kingdom Climate Impacts Programme (UKCIPS) with evidence of a trend towards winter increases in the north-west of the country and summer decreases in the south-east. Secondary climate indicators such as frequency of 'hot' and 'cold' days were found to reveal more variable trends.

“…The identity of thresholds for extreme events depends on the consequences of their changes; thus, the thresholds differentiate among their respective regions [8]. To identify and quantify extreme events, a climate extreme index (CEI) was introduced in the United States in 1996.…”

“…A common tool to understand and assess the precipitation patterns over a region is to use extreme precipitation indices based on daily precipitation series, as indicators of climate change, (Jones et al, 1999;Karl et al, 1999;Brunetti et al, 2001). A considerable number of extreme precipitation indices are described and analyzed in the literature.…”

“…Klein Kostopoulou and Jones, 2005) and the other category is based on statistical quantities such as percentiles, which are more appropriate for regions that contain a broad range of climates (Haylock and Nicholls, 2000;Klein Tank and Können, 2003). The use of extreme precipitation indices are recommended by the joint working group on climate change detection of the World Meteorological Organization -Commission for Climatology (WMO-CCL), the Research Programme on Climate Variability and Predictability (CLIVAR) (Peterson et al, 2001), and the CLIVAR/GCOS/WMO workshop on indices and indicators for climate extremes (Karl et al, 1999) that has released a list of recommended indices.…”

Abstract. Most of the actual studies and previews of future rainfall patterns, based on past observed records for Mediterranean climate areas, focus on the decline of the rainfall amounts over the years, and also on the increase of the frequency of heavy/intense rainfall events particularly in the winter season. These changes in heavy rainfall events may have severe implications and impacts on soil erosion resulting in increased soil degradation risks.The objective of the present work is to evaluate the spatial distribution of extreme precipitation events in Southern Portugal, using a geostatistical approach to assess the relationships between spatial and temporal extreme rainfall patterns. The used dataset comprises a set of 105 stations' records of daily precipitation within the period 1960-1999. Two indices of extreme precipitation were selected to be computed based on the daily precipitation observation series: one representing the frequency of extremely heavy precipitation events (R30) and another one characterizing flood events (R5D).The space-time patterns of the precipitation indices were evaluated and simulated using a geostatistical approach. Despite no significant temporal trends were detected on the calculated indices series, the space-time decadal patterns are becoming more continuous in the last two decades than the previous ones.
