In this paper will show an ethnography about the visit of El Niño Doctor to the city of Puebla in 2019 to participate in the Holy Friday procession, along with other sacred entities that also parade in said ritual act. The remarkable thing about this religious act is that it is the first time that both the mentioned sacred infantile entity and El Señor de las Maravillas meet in the capital city of Puebla. Both sacred entities are the most popular in the federal entity of Puebla. Using the resources of symbolic anthropology, mainly, the cultural and political impacts that said religious event produces a little beyond the sphere of religion are shown. [ABSTRACT FROM AUTHOR]

Landslides triggered by rain have caused many human and economic losses in Colombia, especially in the department of Antioquia. According to DesInventar database since 1900 until 2017, 3478 landslides were recorded in the territory of Antioquia and these have left over 2065 fatalities and 74654 damaged homes. This paper presents spatial and temporal rainfall variability and their relationship with historical landslides events under the influence of ENSO in the nine sub-regions of Antioquia. For this purpose, daily rainfall data obtained from 27 IDEAM weather station and 5368 landslides reported in SIMMA and DesInventar database were used in a time window analysis between 1985 and 2016 (32 years). Also, temporal analyses and correlations were performed in daily, monthly and annual scale. According to the results of this study, the occurrence of landslides exhibits bimodal behavior according to temporal rainfall variability, and the strong effect of the cold phase of the ENSO (La Niña) has a strong influence on them. Moreover, landslides showed significant sensitivity to the time-series of rainfall linked to the different sub-regions of Antioquia. The understanding of spatial-temporal rainfall variability in tropical mountains environments is a key element for an appropriate risk management and early warning system implementation and design for hydro-meteorological hazards.

This paper aims at determining the phenological parameters of the native forest of the Semiarid-Chaco and Serrano-Chaco natural regions in the province of Santiago del Estero, Argentina, using TIMESAT software and the temporal series of NDVI VEGETATION SPOT. Since the study was carried out during a period (1998 to 2009) affected by ENSO, both wet and dry seasons were taken into account. Samples of the Semiarid Chaco forest, and Sierras de Guasayan and Sierras de Sumampa-Ambargasta mountain forests were analyzed. The Semiarid Chaco forest and Sierras de Sumampa-Ambargasta mountain forests showed variations at the beginning of the growing seasons between periods. Sumampa-Ambargasta mountain forests were the most affected. During the wet period, the Semiarid Chaco forest experienced its midpoint in autumn while Sierras de Guasayan and Sierras de Sumampa-Ambargasta mountain forests had theirs in summer. However, during the dry period the three areas underwent their midpoints in autumn. This displacement could be related to the strategic adaptations of the middle and lower forest strata to efficient water use. The Semiarid Chaco forest experienced, in both periods, growing seasons with similar fully integrated production, base and width. On the other hand, Sierras de Guasayan forest showed growing seasons with more fully integrated production in the dry season, a fact that could be the result of NDVI saturation effect during the wet period. Sumampa-Ambargasta mountain forests had similar growing seasons with fully integrated production in both periods. However, the growing season during the dry period had smaller base, length and width. The productivity of the seasonally active vegetation of the three areas showed no significant differences between the periods, which could be due to their greater biodiversity, stratification and the presence of woody species with deep roots.

The Gulf of California is characterized as a semi-closed sea and an evaporation basin. It has been divided into various physical and bio-geographical zones, due to characteristic dynamics of each zone. The goal of this paper was to study the interannual chlorophyll variability from September 1999 to December 2002 during El Niño and La Niña conditions. Weekly composites for the study period with 9 km per pixel resolution were obtained from SeaWiFS imagery data. The spatial distribution of chlorophyll means suggest that the Gulf of California can be divided into three zones: oligotrophic (gulf mouth), mesotrophic (central area) and eutrophic (coastal region, north area and the Big Islands). The seasonal chlorophyll variability indicates a dominant annual signal. The interannual variability of chlorophyll in the Gulf of California is evident from El Niño 1997-1998 and La Niña 1998-2001 events. The effect on chlorophyll distribution is strong during El Niño 1997-1998, but the change to cold conditions La Niña during 1998-1999 is appreciated in negative anomalies, but in positives in 2000 and 2001 years.

In this paper, we propose the representation of the Southern Oscillation Index (SOI) dynamics using a new class of nonlinear hybrid model. In this new model, the non-linearity in the mean is represented by an adaptive neurofuzzy inference system (ANFIS), while the variance is represented using an autoregressive conditional heterocedastic (ARCH) component. In addition, a specification strategy for the proposed model, which is based on a battery of statistical tests is developed. The results indicate that the proposed model captures in a better way the main features of the studied time series, when compared to other competitive models. [ABSTRACT FROM AUTHOR]

Independencia Bay can be considered as one of the most productive invertebrate fishing grounds worldwide. One of the most important exploited species is the scallop (Argopecten purpuratus) with strong catching fluctuations related to El Niño and La Niña events and to inadequate management strategies. During strong warming periods annual landings reach up to 50 000t in an area of about 150 km² and during cold years they remain around 500 to 1000 t. This study analyses the changes in scallop landings at Independencia Bay observed during the last two decades and discusses the main factors affecting the scallop proliferations during the El Niño events. In this way data on landings, sea surface temperature and those related to growth, reproduction, predation, mean density and oxygen concentration from published and unpublished papers are used. The relationship between annual catches and average water temperature over the preceding reproductive period of the scallop over the past 20 year's period, showed that scallop production is affected positively only with strong El Niño such as those of 1983 and 1998. Our review showed that the scallop stock proliferation can be traced to the combined effect of (1) an increase in reproductive output through an acceleration of gonad maturation and a higher spawning frequency; (2) a shortening of the larval period and an increase in larval survival; (3) an increase in the individual growth performance; (4) an increase in the juvenile and adult survival through reduction of predator biomass; (5) an increase in carrying capacity of the scallop banks due to elevated oxygen levels. When discussing the factors that contribute to the development of the scallop population during an El Niño event, the fishery must be considered in detail. Since the volume of the catch not only depends on the relative abundance of the species, fishing efforts and strategies were analyzed in order to explain different levels of scallop production during El Niño 1983 and 1998.
