La ocurrencia de fuertes lluvias es una de las características más llamativas de los fenómenos ENSO en la costa noroeste de Perú. Algunos efectos de estas precipitaciones en el paisaje y la biota pueden permanecer registrados en diferentes tipos de marcadores naturales (características litorales, ...

Es necesario continuar haciendo esfuerzos para establecer un registro homogéneo y lo más completo y confiable posible de los eventos del fenómeno ENSO. La región de Piura tiene una alta sensibilidad al fenómeno, cuya presencia da lugar siempre a las abundantes lluvias. Por esto, las fuentes históricas ...

The Collaborative Research Network (CRN) project the assessment of present, past and future climate variability in the Americas from freeline environments, currently under development by institutions of Argentina, Bolivia, Canada, Chile and United State. The goal of this CRN project is the recovery ...

The recent interest in El Niño Phenomenon stems from: 1) our better understanding of the physical processes involved, which in turn has made possible its early prediction, 2) the realization that it affects the climate at a global scale, and 3) its unusual recent intense episodes and their higher ...

We present a preliminary evaluation of the performance of three different cumulus parameterization schemes in the ICTP Regional Climate Model RegCM3 for two overlapping domains (termed ‘‘big’’ and ‘‘small’’) and horizontal resolutions (50 and 25 km) in the Caribbean area during the summer (July–Augu ...

The Mantaro River Basin (34550,08 Km2) is located on the eastern slope of the central Peruvian Andes, between the coordinates 10º34’30’’S- 13º35’30’’S/ 73º55’00’’W- 76º40’30”W. This is a very complex basin due to its geomorphology, with almost 85% of its territory located above 3000 masl. This basin ...

The nature of the South Pacific convergence zone (SPCZ) is addressed by focusing on the dry (and cool) zone bounded by it and the coast of South America through numerical experiments. As shown in a companion paper, this dry zone is due, to a large extent, to orographically forced subsidence. Here it ...

As part of the study on the Mantaro river basin’s (central Andes of Peru) current vulnerability to climate change, the temporal and spatial characteristics of frosts were analysed. These characteristics included intensity, frequency, duration, frost-free periods, area distribution and historical trends. ...

The response of the equatorial and South American coastal ocean circulation to the anomalous March 2002 wind jet extending from the Gulf of Panama to 6° S is studied in a linear ocean model. Two experiments were performed: one without continental boundaries and the other with an eastern boundary at ...

Muchas actividades agrícolas dependen significativamente de la precipitación y la temperatura, afectando la producción y productividad de los cultivos. La cuenca del río Mantaro, (Junín-Perú), está expuesta a una alta variabilidad climática debido a su ubicación y características geográficas. Además, ...
