“…Observed and simulated changes in precipitationAlthough we do not present the data here, the analysis of daily precipitation data over the period 1925-2010 does not show significant trends in annual accumulation for Roussillon, a result consistent with other studies on the Western Mediterranean basin(Brunetti et al 2004(Brunetti et al , 2006Gonzalez- Hidalgo et al 2009;Altava-Ortiz et al 2011;Camuffo et al 2012). Seasonal patterns are variable intra-annually but remain relatively stable inter-annually, even if some recent changes have been detected.…”

The viticultural system and climate change: coping with long-term trends in temperature and rainfall in Roussillon, France

et al. 2013

International audienceClimate change could put at risk viticultural areas situated at the hotter margins of Vitis vinifera growth climatic range. We focus on two such regions with a Mediterranean climate (CSb type in Köppen classification): Côtes-du-Roussillon in southern France and McLaren Vale in South Australia. They share a relatively similar recent climate evolution. Based on data from two synoptic weather stations, Perpignan (France) and Adelaide (Australia), with daily time series running from 1956 to 2010, we identified changes in temperatures and precipitation patterns, especially an increase of maximum temperatures, of the Huglin Index and Cool Night Index. According to climate models (data from DRIAS project in France, CSIRO Mk3.5 model in Australia) this tendency is likely to continue in the future. In these two regions, two red varieties are mainly grown: Grenache and Shiraz, as they are relatively well suited to Mediterranean climate and to market demand in volatile global markets. Based on twenty in-depth semi-structured interviews in both regions, we identified that vineyard management practices -current and planned for a near future, are based in their vast majority on economical considerations. Concerns of producers include: maintaining income and market position by producing optimal yields, a constant wine style and quality and a diversified offer. In addition, producers feel they have to deal with an increasing uncertainty regarding climate variability, confirmed by climate data. Adaptation strategies of producers to various types of changes, including climate change, take into account a multiplicity of factors, in which climate change is often not the main concern. Two opposite systems of legislation and cultural traditions in the two regions also make the choice and implementation of adaptation strategies very different. Thus the sensitivity of viticultural systems to climate change depends strongly on non-climatic factors

“…Half a century is a relatively short period for precipitation trend detection since historical and longer series could show secular cycles or swings (Camuffo et al 2013;De Lima et al 2010). Several authors observed these cycles or swings in the Mediterranean Basin also concerning temperature and sea surface temperature (Camuffo et al 2010;Lionello et al 2006;Pisacane et al 2006).…”

Recent trends in seasonal and annual precipitation indices in Tuscany (Italy)

Global warming alters the hydrological cycle since a rise in temperature leads to an increase in the moistureholding capacity of the atmosphere at a rate of about 7 %/°C . This fact can influence the global, but also local characteristics of precipitation, such as total amount and intensity. Therefore, it is important to study changes in rainfall regime in regions with complex orography, like Tuscany, where there are strong spatial gradients in precipitation amounts. The aim of this study is to look for temporal change in precipitation from 1955 to 2007 searching for spatial differences. Daily data of 21 meteorological stations were analyzed to identify trends in seasonal and annual precipitation indices. Cluster analysis applied to principal components was applied to identify homogeneous groups of stations. A decrease in precipitation was observed at annual time scale, during winter and spring, especially in northwestern areas. Wet days highlighted a decrease in all of Tuscany, due to the same seasons. In northern Tuscany, the decrease in rainfall amount was mainly determined by a lower frequency of rainy events which in turn caused a decrease in the occurrence of extreme daily precipitation events (75th, 90th, and 95th percentile). In central-southern Tuscany, no significant changes were observed except for an increase in precipitation fraction, due to extreme events and in mean daily total amount for wet days. These results are consistent with recent findings for the Mediterranean area and confirm the usefulness of cluster analysis for the analysis of the spatial distribution of precipitation.

“…Although very long and important terrestrial surface and upper air data series have been digitized and processed (e.g. Alcoforado et al ., for Portugal; Camuffo and Bertolin, , Camuffo et al ., and Camuffo et al ., for Italy and the Western Mediterranean; Domínguez‐Castro et al ., for Spain; Brunet et al ., and Ashcroft et al ., for the Mediterranean North Africa and the Middle East; Slonosky, for Canada; Ashcroft et al ., for southeastern Australia; Stickler et al ., for global upper‐air data, to give only very few examples), a huge fraction have still not been digitized (see also Bosilovich et al ., ). This also applies to historical marine observations from exploration, naval, postal, merchant and passenger ships.…”

Quantitative approaches to climate risk management such as mapping or impact modelling rely on past meteorological data with daily or sub‐daily resolution, a large fraction of which have not yet been digitized. Over the last decade or so, a number of projects have contributed to the rescue of some of these data. Here we provide a summary of a survey we have undertaken of several meteorological and climate data rescue projects, in order to identify the needs of climate data rescue services. To make these efforts more sustainable, additional integrated activities are needed. We argue that meteorological and climate data rescue must be seen as a continuous, coordinated long‐term effort. Technical developments (e.g. data assimilation), new scientific questions (e.g. process understanding of extreme events) and new social (e.g. risk assessment, health) or economic (e.g. new renewable energy sources, agriculture and forestry, tourism, infrastructure, etc.) services are highlighting the immense value of data previously neglected or never considered. This continuous effort is currently undertaken by projects of various sizes, structure, funding and staffing, as well as by dedicated programmes, ranging from those within many national weather services down to “grassroots” initiatives. These activities are often not sufficiently coordinated, staffed, or funded at an international level and will benefit considerably from climate data rescue services being established within the Copernicus Climate Change Service (C3S) (https://climate.copernicus.eu/).
