During summer, they operate as localised wind maximum within the lower 1–2 km of the atmosphere, channelled by the Andes, terminating in southeastern South America. They are controlled by Amazonian wind patterns, which are influenced and controlled by patterns of insolation. They transport large amounts of moisture from the Amazon basin to the monsoonal anticyclone over Bolivia.
During summer, they function as localized wind maxima within the lower 1–2 km of the atmosphere, guided by the Andes, concluding in southeastern South America. They are governed by Amazonian wind patterns, which are affected and managed by insolation patterns. They transport substantial amounts of moisture from the Amazon basin to the monsoonal anticyclone over Bolivia.
