Abstract
The objective of this work is to analyze the spatio-temporal distribution of Global Horizontal Irradiation (GHI) on a regional scale and its relationship with frequent synoptic situations in the south of the Pampeana region (Argentina). It was verified that the latitudinal pattern of distribution of the GHI is modified in the region by cloud cover, which is in turn determined by the seasonal dynamics of action centers and the passage of fronts in summer and winter. The South America Monsoon System (SAMS) defines differential situations of cloudiness and rainfall in the region, which affect GHI. GHI increased successively between the decades 1981–2010, a factor associated with the variability of rainfall that characterizes the region.
Highlights
Solar radiation is the main source of energy for all climatic processes and the determining factor of the intensity and distribution gradients of different climate elements
Temperate climates with oceanic influence typical of the south pampeana region have a higher frequency of rainfall, low potential evapotranspiration and conditions leading to fog formation
In the coastal areas of the Pampeana region dominate maritime Tropical air masses which emerge from the western edge of the South Atlantic Anticyclone, whose entry to the continent favors the development of cloudiness and precipitation and the summer storms that occur in the region (Capelli de Steffens, Piccolo, and Campo de Ferreras 2005; Scian 2010; Celemín 1984; García 2013)
Summary
Solar radiation is the main source of energy for all climatic processes and the determining factor of the intensity and distribution gradients of different climate elements (such as temperature, humidity and atmospheric pressure, among others). Radiation is the ultimate cause of climate differences and affects all climate-related phenomena (Patton, Alexander, and Kramer 1978). While site conditions (latitude and topography) determine the intensity and duration of insolation, the earth’s atmosphere filters incident radiation by absorption, diffusion and reflection processes (Abal 2012; Patton, Alexander, and Kramer 1978; Oke et al 2017; Sengupta et al 2017). GHI is the geometric sum of direct and diffuse radiation received on a surface (Hermosillo Villalobos, Gudiño Ayala, and Mendoza Ramírez 1995; Habte et al 2017)
