MULLER, Gabriela Viviana; FERNANDEZ LONG, María Elena  y  BOSCH, Ezequiel. Relación entre la temperatura de la superficie del mar de diferentes océanos y los rendimientos de maíz en la Pampa Húmeda. Meteorologica [online]. 2015, vol.40, n.1, pp.5-16. ISSN 1850-468X.

The sea surface temperature anomalies (SST) are closely related to the precipitation anomalies in central and eastern Argentina and therefore they are related to some crops in the Argentine Pampa region as well. The objective of this paper is to analyze the relationship between SST in the Pacific, Atlantic and Indian Oceans and maize yields in the Pampa region. It is found that maize yields respond in different ways to the SST variability, except for the south, southeast and west of Buenos Aires province and the east of the La Pampa province, where the signal is either weak or nonexistent. It is also found that some oceanic regions have a significant influence over the rest of the Pampa region, in particular the subtropical Pacific Ocean, the equatorial Pacific Ocean ENSO region, the Indian Ocean dipole (IOD) and the tropical and subtropical western Atlantic Ocean mainly in the spring and in some cases in the fall.

Palabras clave : Yields; Argentine Pampa región; Sea surface temperatures.
