Understanding the intra‐annual distribution of rainfall is an important element for climatic classification and serves as a basis for natural resources management. The present study analyses multi‐annual irregularities of the rainfall distribution throughout the year in the period 1941–2010, in the hydrographic basins of the Iberian Peninsula. In order to analyse its variation, the rainfall centralisation and dispersion parameters throughout the annual cycle were previously defined and calculated for each year. Inter‐annual series of both parameters were generated, which allowed detecting their temporal behaviour in each of the basins and relating differentiated geographic areas. Independent of the total annual rainfall, greater temporal simultaneity is observed in the fluctuations of the intra‐annual parameter ‘centralisation’ in the Atlantic basins and wider inter‐annual oscillations in the Mediterranean basins. Around the year 1970, there was a displacement in the predominance of autumn rains, although the process is inverted in the last decades. Also from the decade of 1970 there is a general increase in the inter‐annual variability of the ‘dispersion’ parameter, especially in the basins that drain towards the Atlantic Ocean. The ‘dispersion’ parameter allows detecting latitudinal (Cantabrian vs. Guadalquivir) and longitudinal (Atlantic vs. Mediterranean) patterns of intra‐annual rainfall distribution irregularity in the Iberian Peninsula. The results obtained are also associated to atmospheric general circulation patterns of the North Atlantic Oscillation and the Western Mediterranean Oscillation. The monthly winter values of the North Atlantic Oscillation present a marked influence on dispersion, especially in the basins that discharge into the Atlantic Ocean, which show a double gradient: decreasing longitudinally from the Atlantic coast to the Mediterranean coast and latitudinally from north to south.

“…Low solar irradiance promotes the development of frequent and persistent atmospheric blocking events (Moffa-Sánchez , 2014). These blocking events usually last a sufficiently long time (i.e., between 1 and 3 weeks) to induce significant climate anomalies over a wide area of Europe (Trigo et al, 2004), although the occurrence of these anomalies is dependent on the location (Sousa et al, 2015). The position, frequency and persistence of these blocking events on the central North Atlantic Ocean are mainly conditioned by the phase of the NAO (Shabbar et al, 2001).…”

This work presents two novel climate-related time series for the northwest of Portugal. The first is an AD 1626-1820 triennial-resolvedwine production series, based on the Benedictine accounts from six monasteries of the Entre-Douroe-Minho (EDM) region. The second, an AD 1654-2010 benthic foraminiferal record from the Caminha salt marsh, located in the lowerestuaryof the MinhoRiver. The serieswereanalysedtogether for the common periodto outlinehow both palaeoclimatic proxies respond to the most likely natural environmental drivers of temporal variability, solar forcing included. Singular spectral analysis revealed a common significant multidecadal periodicity agreeing with recognized long-term changes in solar activity, i.e. the Lower Gleissberg cycle (50-80 years). The application of wavelet analysis allowed the detection of high coherence at this time scale (centred at c. 64 years) between marsh foraminifera and both total solar irradiance and the North Atlantic Oscillation index. This relationship persists throughout the c. AD 1730-1875period. The continuouswavelettransform results for wine productionwereinconclusive. As the timespan analysed is recognized as one of high socio-economic and political distress, the main human-driven impacts on wine production, particularly in the two periods of greatly reduced solar activitythe Maunder and Dalton Minimaare reviewed in the light of the available historical records. In addition to a documented climate-related agricultural crisis in Portugal, damage and losses to wine production may have been triggered by several local and international conflicts in which the country was involved. But to what extent the two influences contributed to the wine production variations observed in the EDM region during both periods remains an open question.
