“…Rodríguez-Puebla et al (1998) showed a significant correlation between annual precipitation in the central/western region and the December NAO index. Also, Martín-Vide & Fernández (2001) indicated a spatial gradient of the NAO influence on precipitation from the southeast of the Iberian Peninsula (strong) to the north and east (weak). These authors also showed important monthly differences in the NAO influence.…”

The evolution of droughts in the Iberian Peninsula from 1910 to 2000 is analysed. Fifty-one monthly precipitation series, distributed homogeneously over the region were examined. Drought analysis was carried out by means of the standardized precipitation index, at a 12-month temporal scale. The main drought episodes were identified at the scale of the entire Iberian Peninsula, with the most intense droughts recorded in the 1940s, 1950s, 1980s and 1990s. However, the spatial distribution of drought episodes can be very diverse. The Peninsula was divided into four homogeneous areas according to drought history. These areas are well-defined spatially as the north, northeast, southeast and central/western areas. The main drought episodes usually affected wide areas of the Iberian Peninsula, but sometimes a drought episode affects one region, whilst other areas are subject to humid conditions. The possible causes of the spatial differences in temporal drought behaviour are discussed, and the usefulness of drought regionalization in the context of drought management schemes is highlighted.

“…The NAO affects winter precipitation significantly in the Iberian Peninsula (Trigo et al, 2004;Ullbrich et al, 1999;Martín-Vide and Fernández, 2001). Nevertheless, other atmospheric circulation patterns can be identified during the boreal winter in Western Europe (Barnston and Livezey, 1987).…”

“…Several papers have indicated that interannual precipitation variability and drought occurrence in Spain are related to changes in the main atmospheric circulation modes on global and hemispheric spatial scales (von Storch et al, 1993;Rodríguez-Puebla et al, 1998;Rodó et al, 1997;Pozo-Vázquez et al, 2001Martín-Vide and Fernández, 2001). Other papers have analysed the influence of weather types on precipitation (Trigo and DaCamara, 2000;Goodess and Palutikof, 1998;Martín-Vide, 2002;Goodess and Jones, 2002;Corte-Real et al, 1998;Esteban et al, 2005).…”

This paper analyses the spatial and temporal variability of winter droughts in a semi-arid geographic gradient in Northeast Spain, from the Pyrenees in the north to the Mediterranean coastland in the south. Droughts that occurred between 1952 and 1999 were analysed by means of the Standardised Precipitation Index (SPI). The influence of the weather-type frequency and of the general North Atlantic atmospheric circulation patterns was analysed. The results indicate that winter droughts show an important spatial variability in the study area, differentiating three well-defined patterns. These correspond to the Pyrenees, the centre of the Ebro Valley, and the Mediterranean coastland. General negative trends in winter SPI have been found, which are indicative of the increase in winter drought conditions in the study area. Nevertheless, important spatial differences have also been recorded. Dominant north-south gradients in the influence of weather types are shown. Moreover, the negative trends in winter-SPI values agree with the negative trend in the frequency of the weather types prone to cause precipitation, such as the C, SW and W weather types and the increase in the frequency of A weather types. Nevertheless, in the Mediterranean coastland, the positive trend in SPI values agrees with the increase in the frequency of weather types of the east (E, SE), which are prone to cause precipitation in this area. Interannual variations in the frequency of the different weather types have been highly determined by different general atmospheric circulation patterns, mainly the North Atlantic Oscillation (NAO). Nevertheless, the correlation between the time series of weather-type frequency and the winter SPI is higher than that found between the SPI and the NAO. Thus, although the interannual NAO variability explains a high percentage of the interannual differences in the frequency of different weather types, it is not sufficient to explain the spatial and temporal variability of droughts, which respond better to atmospheric variability at more detailed (synoptic) spatial scales.

“…The Northern Atlantic Oscillation (NAO) refers to the atmospheric mass distribution between the Arctic and the subtropical Atlantic and has a strong impact on the European climate, including that of the Iberian Peninsula (where low NAO leads to a humid growing season; Martín-Vide & Fernández-Belmonte, 2001), as well as that of the eastern coast of North America. NAO can be assessed through an index based on the pressure differences between a northern location (usually Iceland) and more southern locations (usually the Azores Islands or the Portuguese coast).…”

Aim of study: Our main goal is to determine the relationship between cone production and radial growth in Pinus pinaster Ait. under different climatic conditions across the Iberian Peninsula.Area of study: Coca Intensive Sampling Plateau, Northern Plateau (Spain). Material and methods:Cone counts were conducted on an intensive monitoring plot in Coca (North-Central Spain) during the years 2000, 2006 and 2007. A ZIP (zero-inflated Poisson) model was adjusted for simultaneously estimating the probability of obtaining crop cones and its amount. The Northern Atlantic Oscillation (NAO) index was used as explanatory variable, together with a wide variety of tree and local stand variables. Climate (as evaluated by NAO), local stand density (here estimated from the six nearest trees), tree size and vigor, competition and growth efficiency significantly influenced both occurrence and intensity of cone production.Main results: ZIP models for predicting reproductive effort seems an adequate tool to predict reproductive responses to climatic fluctuations and the resulting future species distribution in the face of climate change, as well as to identify silviculture actions that would promote reproductive success in naturally-regenerated stands, list and discuss relevant results (including numeric values of experimental results).Research highlights: Climate, stand density and tree conditions (size and vigor, competition and growth efficiency) influence significantly both cone occurrence and intensity of fruiting as shown by a ZIP model. As the climate variables included in the model (based on Northern Atlantic Oscillation, NAO) are general and easily obtained, the proposed model has practical applicability to predicting Pinus pinaster cone production in the Iberian Peninsula.
