Un amor estratificado: narrativas, prácticas y la infraestructura del amor de tres mujeres chilenas de diferentes estratos sociales

This article is an exploratory study that seeks to incorporate the stratification variable to the current academic discussion about the changes in the forms of intimacy and the way that love is lived in late modernity asthe result of individuation processes. It also emphasizesthe material conception of love, considering practices and objects of consumption as determining factors en the experience of love. Through an exploratory study based on narrative analysis of three Chilean women of different socioeconomic strata, I seek to problematize the conceptual categories used in the sociological debate about love. As we shall see, the stratification factor shows that love is experienced in different ways depending on the social strata and also changes its material elements.El presente artículo es un estudio exploratorio que busca incorporar la variable estratificación a la actual discusión académica en torno a lastransformaciones en la intimidad y lasformas de vivir el amor en la modernidad tardía producto de los proceso de individuación. Asimismo se hace hincapié en la conceptualización material del amor, considerando las prácticas y objetos de consumo amoroso como factores determinantes de la vivencia del amor. A través de un estudio exploratorio/comparativo basado en el análisis de historias de vida de tres mujeres chilenas de diferentes estratossocio-económicos se busca problematizar las categorías conceptuales que hoy se utilizan en el debate sociológico en torno al amor. Como se verá, el factor estratificación demuestra que el amor se vive de formas diferentes dependiendo del estrato social así como también de las materialidades

Assessing the Influence of the MJO on Strong Precipitation Events in Subtropical, Semi-Arid North-Central Chile (30°S)

This is the publisher's version, also available electronically from http://journals.ametsoc.org/doi/abs/10.1175/JCLI-D-11-00679.1.Annual precipitation in subtropical, semiarid north-central Chile (30°S) during rainy years comprises a few (3–5) strong events in the fall and winter, which are presumably modulated by the Madden–Julian oscillation (MJO). Precipitation from 1979–2009 was recorded daily at three stations along the Elqui Valley. The relationship between the MJO and precipitation is investigated from two perspectives: 1) examining a MJO index (MJOI) based on the actual precipitation events and 2) examining the likelihood of precipitation based on a favorable MJOI. About 80% of the strong precipitation events at the coast in La Serena are related to an active MJO near the central equatorial Pacific. These events are often typified by broad, slow moving synoptic systems in phase with the MJO propagation. Blocking in the far southeast Pacific is associated with precipitation 75% of the time, while deep troughs make up the rest. A relationship between a MJOI and strong rainfall suggests that, though it could be used as a potential diagnostic, the number of cases where there is a favorable MJOI but no precipitation (i.e., false alarms) limits its utility. Additional criteria such as the Southern Oscillation (SO) and Antarctic Oscillation (AAO) phases were used to reject false alarms. Rejecting cases with positive values of the SO index reduced the number of false alarms from 70% to 58%, leaving about two false alarms for every correctly diagnosed event. The AAO index could not discriminate between false alarms and real cases. While a favorable MJOI increases the likelihood of precipitation in the Elqui Valley, false alarms remain problematic

The Low-Level Atmospheric Circulation near Tongoy Bay–Point Lengua de Vaca (Chilean Coast, 30°S)

This is the publisher's version, also available electronically from http://journals.ametsoc.org/doi/abs/10.1175/MWR-D-11-00059.1.Strong southerly, terrain parallel winds often occur along the coast of north-central Chile (25°–35°S) embedded in the marine atmospheric boundary layer and the lower part of the capping temperature inversion. Their offshore structure and variability have received considerable attention because of the effect on open-ocean processes and connection with the southeast Pacific cloud layer. Mesoscale low-level circulations linked to the coastal topography (e.g., coastal jets and sea breeze) are less studied in Chile, but are particularly relevant as they alter the upper-ocean circulation and the cloud pattern in the nearshore strip. Surface, radiosonde, and airborne meteorological observations near point Lengua de Vaca (LdV)–Tongoy Bay (TB) at 30°S are used alongside numerical modeling to understand the local circulation near a prominent upwelling center. Most observations were gathered during the Variability of the American Monsoon Systems (VAMOS) Ocean–Cloud–Atmosphere–Land Study Chilean Upwelling Experiment (VOCALS-CUpEx) during two weeks in late spring 2009. The regional topography resembles other major capes, but south of TB and east of LdV there is a low (100–300 m), dry marine terrace bounded by high elevation at the coast (~600 m) and farther inland. Coastal soundings 25 km upstream of LdV revealed a southerly wind maximum near the surface and another at 900 m separated by a destabilized layer, deviating from the two-layer model often applied to coastal flow. In the morning a shallow sea breeze penetrates from TB to the marine terrace, but is overridden by southerly flow in the afternoon. Furthermore, between 400 and 900 m, warm continental air is advected from over the marine terrace creating a residual boundary layer over TB. Concurrent with slower changes offshore, the low-level warming over TB leads to a marked cross-shore pressure gradient enhancing the coastal jet just north of LdV

VOCALS-CUpEx: the Chilean Upwelling Experiment

This is the publisher's version, also available electronically from http://www.atmos-chem-phys.net/11/2015/2011/acp-11-2015-2011.html.The VAMOS Ocean-Cloud-Atmosphere-Land Study Regional Experiment (VOCALS-REx) was a major field experiment conducted in spring of 2008 off southern Peru and northern Chile, aimed at better understanding the coupled climate systems of the southeast Pacific. Because of logistical constrains, the coastal area around 30° S was not sampled during VOCALS-REx. This area not only marks the poleward edge of the subtropical stratocumulus cloud regime (thus acting as a source of transient disturbances) but is also one of the most active upwelling centers and source of surface ocean kinetic energy along the Chilean coast. To fill such an observational gap, a small, brief, but highly focused field experiment was conducted in late spring 2009 in the near-shore region around 30° S. The Chilean Upwelling Experiment (CUpEx) was endorsed by VOCALS as a regional component. CUpEx included long-term monitoring, an intensive two-week field campaign and off-shore research flights. Our goal was to obtain an atmospheric/oceanic dataset with enough temporal and spatial coverage to be able to document (a) the mean diurnal cycles of the lower-troposphere and upper-ocean in a region of complex topography and coastline geometry, and (b) the ocean-atmosphere response to the rapid changes in coastal winds from strong, upwelling-favorable equatorward flow (southerly winds) to downwelling-favorable poleward flow (northerly winds). In this paper we describe the measurement platforms and sampling strategy, and provide an observational overview, highlighting some key mean-state and transient features

Episodes of strong flow down the western slope of the subtropical Andes

ABSTRACT Nocturnal flows down the narrow Andean valleys within the western slope of the subtropical Andes (central Chile) are episodically enhanced by easterly downslope winds that flow into the Santiago basin over the radiatively cooled air above the surface. Local, regional, and large-scale data have been used here to characterize the mean features of these episodes. About 80% of easterly downslope flow episodes in austral winter are forced by a reversal in the sea level pressure gradient along the coast of south-central Chile, when a midlatitude cold high migrates from southern Chile eastward across the Andes under midtroposphere SW winds associated with a warm ridge aloft. Under these circumstances low-level, easterly (offshore) flow sets in, producing a compensating downslope flow that subsides over central Chile. The remaining cases are associated with prefrontal conditions under a midlatitude trough with NW winds aloft. Since in most of these cases the easterly low-level flow occurs beneath westerly flow higher above, these episodes classify as strong windward downslope flows. Within the Andean valleys and canyons, the near-surface air experiences a sensible warming and drying at night and early morning during these episodes, as the strong downvalley winds tend to destroy the surfacebased radiative inversion and mix down warmer air from aloft. At the exit region of these valleys into the central basin, these downslope flows in austral winter are not able to flush the cold air pool there. Hence, dawn surface temperatures over the basin tend to be lower than average as clear skies and dry subsiding air aloft favor surface radiative cooling. The resulting enhancement of the near-surface static stability hampers the subsequent development of the mixed layer, leading to severe air pollution events in Santiago and other cities in central Chile. A comparative discussion on governing mechanisms with respect to apparently similar phenomena, as gap flow and shallow foehn, is included
