December brings a varied panorama for precipitation in Chile. High pressures will dominate in much of the country, reducing the rains in the southern and southern areas. This generates a significant deficit, especially in regions such as Aysén and Patagonia, where rainfall records are expected to be notably below average, with values that could be more than 50 mm below normal for the month.
Where will the greatest rainfall deficit be recorded?
The south of Chile, from La Araucanía to Los Lagos, will show a significant deficit in its precipitationwith patterns similar to those observed in the Aysén Region. Coyhaique, for example, could receive much less than the 57.3 mm that normally falls in December. This deficit is due to the marked presence of high pressure over the continental territory, which limits the development of rain systems.
What areas will have above average rainfall?
In contrast to the south and Patagonia, Chile’s northern highlands will experience above-average rainfall. Bolivia’s discharge will intensify the storms over the interior areas of Arica, Parinacota, Tarapacá and the north of Antofagasta. This phenomenon responds to the high-altitude anticyclonic circulation that promotes the formation of clouds and summer rains in the north of the country.
What happens in the central and north central area?
In the central zone, which includes from Atacama to the Metropolitan Regionrains will continue to be scarce, in line with the typical dry season of summer. However, the interior could experience higher temperatures, favoring phenomena such as evening convection. In these regions, although large rainfall is not expected, temperatures could reach values higher than 34 °C in interior sectors due to the coastal trough.
How will temperatures behave in December?
The north and north-central part of the country will show below-average temperatures on the coast, while in the interior, higher temperatures will contribute to phenomena such as thunderstorms. In the central-south and the southern zone, the temperatures They will be in line with the averages of the time. In cities like Santiago, maximum temperatures will be around 29 °C, although specific episodes could take them up to 34 °C in interior sectors.
