Wintertime Precipitation Episodes in Central Chile: Associated Meteorological Conditions and Orographic Influences
Publisher: American Meteorological Society
Abstract: Central Chile (32°?35°S) is a mountainous and densely populated strip of land between the South American Pacific coast and the main divide of the Andes, 5000 m in height. In this study, wintertime precipitation episodes ...
The Impact of GPS Precipitable Water Assimilation on Mesoscale Model Retrievals of Orographic Rainfall during SALPEX'96
Publisher: American Meteorological Society
Abstract: The potential of GPS precipitable water (PW) to improve mesoscale model retrievals of orographic precipitation is investigated for a prolonged rainfall event observed during the 1996 Southern Alps Experiment (SALPEX'96). ...
The Atacama Surface Solar Maximum
Publisher: American Meteorological Society
Abstract: olar radiation reaching Earth?s surface is one of the major drivers of climate dynamics. By setting the surface energy balance, downwelling solar radiation indirectly heats the atmosphere and controls the hydrological ...
Effect of the Andes Cordillera on Precipitation from a Midlatitude Cold Front
Publisher: American Meteorological Society
Abstract: The effects of the Andes Cordillera, the major mountain range in South America, on precipitation patterns of baroclinic systems approaching from the southeast Pacific remain largely unstudied. This study focuses on a case ...
Strong Down-Valley Low-Level Jets over the Atacama Desert: Observational Characterization
Publisher: American Meteorological Society
Abstract: he near-surface wind and temperature regime at three points in the Atacama Desert of northern Chile is described using two years of multilevel measurements from 80-m towers located in an altitude range between 2100 and ...
Investigation of a nocturnal cold-air pool in a semi-closed basin located in the Atacama Desert
Publisher: American Meteorological Society
Abstract: In desert environments, intense radiative cooling of the surface during the night leads to rapid cooling of the adjacent air, resulting in a strong temperature inversion conducive to cold air pool formation. In this work ...
Wind Energy Exploration over the Atacama Desert: A Numerical Model–Guided Observational Program
Publisher: American Meteorological Society
Abstract: AbstractOver the past 15 years, Chile?s energy agencies have undertaken a series of projects aimed at evaluating the wind energy potential of the northern part of the country (western South America between 18° and 32°S), ...
