Precipitation diurnal cycle and summer climatology assessment over South America: An evaluation of Regional Climate Model version 3 simulations

Regional Climate Model version 3 (RegCM3) simulations of 17 summers (1988-2004) over part of South America south of 5 degrees S were evaluated to identify model systematic errors. Model results were compared to different rainfall data sets (Climate Research Unit (CRU), Climate Prediction Center (CPC), Global Precipitation Climatology Project (GPCP), and National Centers for Environmental Prediction (NCEP) reanalysis), including the five summers mean (1998-2002) precipitation diurnal cycle observed by the Tropical Rainfall Measuring Mission (TRMM)-Precipitation Radar (PR). In spite of regional differences, the RegCM3 simulates the main observed aspects of summer climatology associated with the precipitation (northwest-southeast band of South Atlantic Convergence Zone (SACZ)) and air temperature (warmer air in the central part of the continent and colder in eastern Brazil and the Andes Mountains). At a regional scale, the main RegCM3 failures are the underestimation of the precipitation in the northern branch of the SACZ and some unrealistic intense precipitation around the Andes Mountains. However, the RegCM3 seasonal precipitation is closer to the fine-scale analyses (CPC, CRU, and TRMM-PR) than is the NCEP reanalysis, which presents an incorrect north-south orientation of SACZ and an overestimation of its intensity. The precipitation diurnal cycle observed by TRMM-PR shows pronounced contrasts between Tropics and Extratropics and land and ocean, where most of these features are simulated by RegCM3. The major similarities between the simulation and observation, especially the diurnal cycle phase, are found over the continental tropical and subtropical SACZ regions, which present afternoon maximum (1500-1800 UTC) and morning minimum (0900-1200 UTC). More specifically, over the core of SACZ, the phase and amplitude of the simulated precipitation diurnal cycle are very close to the TRMM-PR observations. Although there are amplitude differences, the RegCM3 simulates the observed nighttime rainfall in the eastern Andes Mountains, over the Atlantic Ocean, and also over northern Argentina. The main simulation deficiencies are found in the Atlantic Ocean and near the Andes Mountains. Over the Atlantic Ocean the convective scheme is not triggered; thus the rainfall arises from the grid-scale scheme and therefore differs from the TRMM-PR. Near the Andes, intense (nighttime and daytime) simulated precipitation could be a response of an incorrect circulation and topographic uplift. Finally, it is important to note that unlike most reported bias of global models, RegCM3 does not trigger the moist convection just after sunrise over the southern part of the Amazon.

A 700-year paleoecological record of boreal ecosystem responses to climatic variation from Alaska

Recent observations and model simulations have highlighted the sensitivity of the forest - tundra ecotone to climatic forcing. In contrast, paleoecological studies have not provided evidence of tree-line fluctuations in response to Holocene climatic changes in Alaska, suggesting that the forest - tundra boundary in certain areas may be relatively stable at multicentennial to millennial time scales. We conducted a multiproxy study of sediment cores from an Alaskan lake near the altitudinal limits of key boreal-forest species. Paleoecological data were compared with independent climatic reconstructions to assess ecosystem responses of the forest - tundra boundary to Little Ice Age (LIA) climatic. uctuations. Pollen, diatom, charcoal, macrofossil, and magnetic analyses provide the first continuous record of vegetation -. re - climate interactions at decadal to centennial time scales during the past 700 years from southern Alaska. Boreal-forest diebacks characterized by declines of Picea mariana, P. glauca, and tree Betula occurred during the LIA ( AD 1500 - 1800), whereas shrubs ( Alnus viridis, Betula glandulosa/nana) and herbaceous taxa (Epilobium, Aconitum) expanded. Marked increases in charcoal abundance and changes in magnetic properties suggest increases in. re importance and soil erosion during the same period. In addition, the conspicuous reduction or disappearance of certain aquatic ( e. g., Isoetes, Nuphar, Pediastrum) and wetland ( Sphagnum) plants and major shifts in diatom assemblages suggest pronounced lake-level. uctuations and rapid ecosystem reorganization in response to LIA climatic deterioration. Our results imply that temperature shifts of 1 - 2 degrees C, when accompanied by major changes in moisture balance, can greatly alter high-altitudinal terrestrial, wetland, and aquatic ecosystems, including conversion between boreal-forest tree line and tundra. The climatic and ecosystem variations in our study area appear to be coherent with changes in solar irradiance, suggesting that changes in solar activity contributed to the environmental instability of the past 700 years.

Modern and fossil corals from Palmyra and Christmas islands

The relationship between decadal to centennial changes in ocean circulation and climate is difficult to discern using the sparse and discontinuous instrumental record of climate and, as such, represents a large uncertainty in coupled ocean-atmosphere general circulation models. We present new modern and fossil coral radiocarbon (D14C) records from Palmyra (6°N, 162°W) and Christmas (2°N, 157°W) islands to constrain central tropical Pacific ocean circulation changes during the last millennium. Seasonally to annually resolved coral D14C measurements from the 10th, 12th-17th, and 20th centuries do not contain significant interannual to decadal-scale variations, despite large changes in coral d18O on these timescales. A centennial-scale increase in coral radiocarbon from the Medieval Climate Anomaly (~900-1200 AD) to the Little Ice Age (~1500-1800) can be largely explained by changes in the atmospheric D14C, as determined with a box model of Palmyra mixed layer D14C. However, large 12th century depletions in Palmyra coral D14C may reflect as much as a 100% increase in upwelling rates and/or a significant decrease in the D14C of higher-latitude source waters reaching the equatorial Pacific during this time. SEM photos reveal evidence for minor dissolution and addition of secondary aragonite in the fossil corals, but our results suggest that coral D14C is only compromised after moderate to severe diagenesis for these relatively young fossil corals.

Jan Steen and The doctor’s visit: Classical Tradition in Golden Age Dutch painting (1st Part)

First one of a two-part analysis on the influence of the Classical Tradition on a favourite theme along the Dutch painters of the Golden Age, The doctor’s visit or The lovesick maiden, especially in the Leiden artist’s production, Jan Steen (1626-1679).

El dinero fuente de pecados en el Inferno de Dante y en la traducción de Pedro Fernández de Villegas (Burgos, 1515)

El trabajo se centra en el análisis de los pecados relacionados con el dinero en el Inferno de Dante y en la primera traducción castellana de la primera cantiga de la Commedia, obra del arcediano de Burgos Pedro Fernández de Villegas. La traducción, compuesta en coplas de arte mayor y acompañada de un enciclopédico comentario, se publicó en 1515. Particular atención se dedica a la reflexión sobre el problema del mal uso del dinero que Villegas desarrolla en la glosa de los cantos en que con más vigor se levanta la voz de Dante para denunciar la gravedad del pecado de la sed de riquezas. Se analiza la postura del traductor español ante el tema comparándola no sólo con la de Dante sino también con la de Cristoforo Landino, autor del Comento sopra la Comedia, obra exégetica que se publicó por primera vez en Florencia en 1481 y que representó el punto de referencia privilegiado de Villegas.

L’influence de la lecture régulière libre de bandes dessinées humoristiques sur le goût de lire d'enfants de cinquième année primaire

De tous les temps, les individus formant une société se sont donné des moyens pour communiquer. Des langages gestuels, oraux ou écrits se sont alors développés. Entre autres processus de communication, nous retrouvons l'écriture et la lecture. Les Égyptiens, 2500 ans avant Jésus-Christ, possédaient déjà un code écrit. Par la suite, et pendant de nombreux siècles, la lecture a été réservée à une certaine élite. C'est avec l'avènement de l'imprimerie et de l'école obligatoire (de 1500 à 1800), que l'on a assisté à une certaine démocratisation de la lecture. De nos jours, la majorité de la population a accès aux livres, aux périodiques et aux journaux, par l'intermédiaire de nombreux points de vente ou de prêt. Depuis un siècle, plusieurs études dans le domaine de la lecture ont été effectuées, allant des préoccupations d'ordre physiologique, sociologique aux études psychologiques ou pédagogiques. La présente recherche appartient à la dernière catégorie, c'est-à-dire qu'elle est d'ordre pédagogique. Nous nous intéressons ici au développement du goût de lire chez des jeunes de dix et onze ans qui fréquentent le système scolaire québécois. Dans ce contexte, nous nous attardons particulièrement à un médium littéraire en général apprécié chez les jeunes lecteurs, c'est-à-dire la bande dessinée humoristique. L'étude menée ici se déroule dans le contexte d'une approche pédagogique particulière que l'on pourrait nommer la lecture régulière libre.

The Evolution of Norms in Trade and Financial Networks in the First Global Age: the case of Simon Ruiz's network

In the 16th century, merchants and bankers gained a social influence and political relevance, due to their capacity of ‘faire travailler l’argent des autres’ (Benassar 1972:50). For the success of their activity, they built evolving networks with cooperative partners. These networks were much more than the sum of all partners. In the case study of the Castilian merchant Simon Ruiz, the network functioned in an unique way and independent from any formal institutional control. Its functioning varied in how different partners were associated and the particular characteristics and contents of these social ties. Being a self-organized network, since the formal institutions of trade regulation and the Crown control didn’t influence the network functioning, the Simon Ruiz network was deeply embedded in the economic and financial performance of the Hispanic Empires, in two different ways. The first, purely commercial. The monopolistic regime which was applied by the two crowns in the trade of certain colonial goods was insufficient to the costs of imperial maintenance. In such manner, particulars tried to rent a contract of exploration of trade, paying an annual sum to the crown, as in the Portuguese trade. Some of these agents also moved along Simon Ruiz’s network. But others were involved in relations with the imperial crowns on a second way, the finance. Maintaining Empires implied a lot of human, technical but also financial means, and most of the times Kings were forced to recur to these merchants, as we will demonstrate. What were the implications of these collaborative relations in both parts? The main goal of this paper is to comprehend the evolution of informal norms within Simon Ruiz’s network and how they influenced cooperative behavior of the agents, particularly analyzing mechanisms of sanctioning, control, punishment and reward, as well as their consequences in different dimensions: future interactions, social repercussions and in agent’s economic health and activity. The research is based in the bills of exchange and commercial correspondence of the private archive of Simon Ruiz, located in the Provincial Archive of Valladollid, Spain.

Reinterpretation de l'Histoire Stratigraphique et Tectonique de la Structure de Serra de El-Rei (Portugal)

Les travaux faits sur le terrain et les interprétations cartographiques de ces dernières années, montrant la pertinence des observations de Paul Choffat au siècle dernier, permettent de préciser l'échelle stratigraphique et de mieux distinguer les phases de l'histoire tectonique de la structure de Serra de EI-Rei. En attendant la publication d'une cartographie très détaillée mettant en évidence le détail des déformations tectoniques, il faut souligner la dissymétrie des deux flancs de cette structure ainsi que le rôle de certaines failles transverses. Sur son flanc nord, la série liasique, allant des dolomies du Lias inférieur au Toarcien inférieur ou moyen, est recouverte stratigraphiquement et en légère discordance par le "Lusitanien" qui remanie à sa base des éléments du Toarcien inférieur ou moyen. Sur son flanc sud, dans la partie centrale, la série stratigraphique liasique est comparable à celle de l'autre flanc, mais les dépôts du Toarcien, plus complets, sont affectés au cours de la zone à Meneghinii par des perturbations synsédimentaires avec fossiles brisés et/ou remaniés et des réductions d'épaisseur. Plus à l'Est, le Toarcien est très réduit et (tectoniquement?) en contact avec le Dogger. Au Sud-Ouest en revanche, prés de Bolhos, la série toarcienne est plus complète et couronnée par l'Aalénien inférieur, mais tronquée par un contact oblique N-S, repris par la tectonique récente. Sur ce flanc, le Bajocien inférieur est représenté mais peu épais; il est suivi par le Bajocien supérieur, le Bathonien et le Callovien très développés qui sont recouverts par un "Lusitanien" épais, très différent de celui du flanc nord. Cette série du Jurassique moyen et supérieur a été décrite dans la thèse de Christiane Ruget (1963). La structure de Serra de EI-Rei constitue une sorte de raccord E-W entre les importantes structures (diapiriques ?) méridiennes de Caldas da Rainha au NE et de Bolhos au SW. II s'agit d'une structure de tectonique distensive, en demi-graben, d'âge jurassique, qui est responsable de la dissymétrie des séries lithostratigraphiques sur ses deux flancs; au Miocène, pendant la compression bétique, cette structure a subi une inversion en constriction. Un modèle de l'évolution sédimentaire du secteur est présenté.
