Este trabajo analiza la relación espacio-temporal entre el Modo Anular del Sur (SAM) y los índices de precipitación (PRCPTOT, WD, R75pTOT, CWD y CDD) en el trimestre octubre-diciembre (OND), en Sudamérica, para el período 1981-2010. A partir del índice de correlación simple se estudia la relación espacio-temporal y se encuentran correlaciones negat...

Climate services provide information on El Niño-Southern Oscillation (ENSO) evolution and predicted seasonal precipitation, broadly used by decision makers from the agriculture sector. However, soil moisture participates in a more complex soil–atmosphere interaction at subseasonal scale. This work aims to identify the ENSO signal on subseasonal pre...

World agriculture production is affected by extreme temperature and precipitation events occuring during the growing stage of the crops. In South and Central America, where a large part of the economy depends on the production of commodities such as Soybean and Maize (SM), it is essential to design strategies for anticipating future climatic extrem...

This study aims to present a comprehensive spatio-temporal performance analysis of two water balance variables, precipitation and evapotranspiration, simulated by two Regional Climate Models (RCM) multi-model ensembles. We evaluate simulations from two RCMs from the Coordinated Regional Climate Downscaling Experiment in the two largest hydrological...

The assessment of ENSO influence on extreme rainfall events over South America will provide useful information to climate services. This research analyzes the performance of eleven global climate models (GCMs) from the Coupled Model Intercomparison Project Phase 5 (CMIP5) using skill score metrics to simulate two climate extreme rainfall indices: m...

Introduction: With 7.0 x 106 km2 the Amazon River basin represents the most important hydrological region in South America. The Amazon discharges approximately 200,000 m3 s-1 becoming the main source of fresh water from the continent to the Atlantic Ocean. Methodology and data: Our aim is to study the representation of precipitation and evapotransp...

The several variables involved in soil-atmosphere interaction were analyzed in South America from seven Global Climate Models (GCM) of CMIP5. Two different periods were used: 1970–2005 as climate reference for historical experiment and 2065–2100 for projections under the Representative Concentration Pathways scenario RCP 8.5. We assessed the climat...

The deficit of daily precipitation, persistent over time (LDS: long dry sequences), causes economic losses in the east‐northeast of Argentina where agriculture production is the main economic activity. For this reason, an improvement in the seasonal prediction of the frequency of precipitation is required. Among several forcings influencing the reg...

Projected changes were estimated considering the main variables which take part in soil-atmosphere interaction. The analysis was focused on the potential impact of these changes on soil hydric condition under extreme precipitation and evapotranspiration, using the combination of Global Climate Models (GCMs) and observational data. The region of stu...

Precipitation or no precipitation persistent over time often became extreme weather conditions with greater regional economic impact. The temporal and spatial variability of these variables, together with the evapotranspiration, is crucial in the east-northeast of Argentina, where rain-fed agricultural production is carried out. In this work, the f...

The interaction between land surface and atmosphere plays an important role in the climate system. Soil-atmosphere feedback mechanisms are analyzed through calculating the hydric condition (HC) of the soil from the water balance. Spatial coherence between HC and the Standardized Precipitation Index (SPI) as well as the circulation patterns associat...

Monthly and daily precipitation extremes over La Plata Basin (LPB) are analyzed in the framework of the CLARIS-LPB Project. A review of the studies developed during the project and results of additional research are presented and discussed. Specific aspects of analysis are focused on large-scale versus local processes impacts on the intensity and f...

CLARIS LPB database was built within the framework of the CLARIS LPB project “A Europe-South America Network for climate Change Assessment and Impact Studies in La Plata Basin” of the European Community’s Seventh Framework Programme (FP7). The main variables available in the database are rainfall, temperature, radiation, heliophany and streamflow c...

El desarrollo de experiencias de laboratorio es un elemento crucial en el proceso de enseñanza-aprendizaje de las ciencias. En este trabajo se ilustran algunas experiencias básicas de la mecánica de fluidos geofísicos que resultaron muy útiles en dicho proceso. Las experiencias, que se realizaron en el marco del Taller de Experimentación en Fluidos...

The climate and its variability represent one of the most important factors to take into account in many productive activities. Such variability mainly depends on the change in the frequency of occurrence or the intensity of extreme events. The extreme hydric conditions play an important role in the development of the crops producing a socio- econo...
