“…Positive tendencies in these months have been also found by Sigró (2004) for Catalonia, del Río et al (2005Río et al ( , 2009 (2001a, 2007) and Ileana and Castro-Díez (2010) for whole Spain. Our results are also in agreement with those mentioned for the Mediterranean Basin (Kutiel and Maheras, 1998;Brunet et al, 2001a;Sigró, 2004;Salat and Pascual, 2006;Capilla, 2008). Nevertheless we have noted that the Spanish temperature over the period has tended to increase in general at a lower level than the results reported by some authors previously mentioned.…”

The spatial distribution of recent mean temperature trends over Spain during the period 1961-2006 at monthly, seasonal and annual time scale is carried out in this study by applying various statistical tools to data from 473 weather stations. The magnitude of trends was derived from the slopes of the linear trends using ordinary least-square fitting. The non-parametric Mann-Kendall test was used to determine the statistical significance of trends. Maps of surface temperature trends were generated by applying a geostatistical interpolation technique to visualize the detected tendencies. This study reveals that temperature has generally increased during all months and seasons of the year over the last four decades. More than 60% of whole Spain has evidenced significant positive trends in March, June, August, spring and summer. This percentage diminishes around 40% in April, May and December. Annual temperature has significantly risen in 100% of Spain of around 0.1-0.2°C/decade according to the Fourth Assessment Report of the IPCC.

“…[54] This is clearly in disagreement with our results (Table 5), which are supported by other groups over different Spanish subregions [Abaurrea et al, 2001;Brunet et al, 2001bBrunet et al, , 2001cBrunet et al, , 2001dBrunet et al, , 2006Galan et al, 2001;Horcas et al, 2001;Morales et al, 2005]. The fact that these studies are mostly analyzing the post-1920 period or have not made any attempt to minimize the screen bias from the analyzed T max and T min records, as well as that in the present study, daytime temperatures have increased twice as much as nighttime temperatures during 1901-2005 (when screen bias minimization from the T max records has had a small effect on the records), points out the robustness of the current results.…”

“…The larger spring and summer contribution to the increases in annual temperatures in all three Spanish curves highlights the key role played by the warm seasons and should be the focus of further studies on the possible attribution of anthropogenically induced regional warming. Similar twentieth century variations have been found by other researchers over mainland Spain [Brunet et al, 2001a;Rodríguez-Puebla et al, 2002;Esteban-Parra et al, 2003a, 2003b and for different subregions: northeastern Spain [Brunet et al, 2001c], the middle Ebro River Basin [Abaurrea et al, 2001], Southern Spanish Plateau [Galan et al, 2001], Segura River Basin [Horcas et al, 2001], and Northern Spanish plateau [Morales et al, 2005]. Agreement in neighboring countries has also been reported, over France by Abarca del Río and Mestre [2006] and over Italy by Brunetti et al [2006].…”

“…[3] Within the last 10 years, many studies, focused on Spanish temperature change on a monthly basis, have shown evidence of warming over the country by analyzing data from groups of stations [e.g., Oñate and Pou, 1996;Esteban-Parra et al, 2003a] or by developing regional time series for peninsular Spain [Brunet et al, 2001a[Brunet et al, , 2001bBrunet et al, 2002;Rodríguez-Puebla et al, 2002;Brunet et al, 2005;Brunet et al, 2006] or for different subregions [Esteban-Parra et al, 1995;Abaurrea et al, 2001;Brunet et al, 2001cBrunet et al, , 2001dGalan et al, 2001;Horcas et al, 2001;Staudt, 2004;Staudt et al, 2005;Morales et al, 2005]. Even though these studies have used different spatial and temporal scales or diverse analytical approaches for assessing data quality and homogeneity, consistent and coherent temporal patterns of warming have been highlighted mainly for the second half of the twentieth century.…”

[1] We analyze temporal and spatial patterns of temperature change over Spain during the period 1850-2005, using daily maximum (T max ), minimum (T min ), and mean (T mean ) temperatures from the 22 longest and most reliable Spanish records. Over mainland Spain, a significant (at 0.01 level) warming of 0.10°C/decade is found for the annual average of T mean . Autumn and winter contributed slightly more than spring and summer to the annual warming over the 1850-2005 period. The overall warming is also associated with higher rates of change for T max than T min (0.11°versus 0.08°C/decade for . This asymmetric diurnal warming increased in the twentieth century (0.17°versus 0.09°C/decade during 1901 -2005). Nevertheless, at many (few) individual stations, the difference between T max and T min is not statistically significant over 1850-2005 (1901-2005). Principal Component Analysis has been carried out to identify spatial modes of Spanish long-term temperature variability . Three principal spatial patterns are found, Northern Spain, Southeastern and Eastern Spain, and Southwestern Spain. All three patterns show similar significant warming trends. The overall warming has been more associated with reductions in cold extremes, as opposed to increases in warm extremes. Estimated trends in the number of moderately extreme cold days (T max < 10th percentile) and moderately extreme cold nights (T min < 10th percentile) show significant reductions of 0.74 and 0.54 days/decade, respectively, over 1850-2005. Moderately extreme warm days and nights (T max and T min > 90th percentile) increased significantly but at lower rates of 0.53 and 0.49 days/decade.

The local hydrological, agricultural and economic activities heavily depend on micro-level rainfall. Therefore, this study examines trends and variability of rainfall in Uttarakhand state of western Himalaya, India. The season and station-wise results of this study differ from India level results. The annual rainfall declined in high altitudes. Similarly, the monsoon rains declined in high altitudes and increased in low altitudes, whereas winter rainfall show mixed trends. The variability of monsoon rainfall was lowest for all stations and seasons, while the winters show low variability. Inter-seasonal variability is recorded highest in plains and lowest in high altitudes.
