VILLEGAS, Nancy; BARRIENTOS, Juan Carlos  and  MALIKOV, Igor. Relationship between ocean-atmospheric parameters and green coffee production in Colombia. rev.colomb.cienc.hortic. [online]. 2012, vol.6, n.1, pp.88-95. ISSN 2011-2173.

The influence of the migration of the Intertropical Convergence Zone (ITCZ) and of the El Niño Southern Oscillation (ENSO) in the production of green coffee in Colombia (1960-2007) was determined. Temporal relationships between the production series of green coffee (unroasted beans) and the series representing the two phenomena of the ocean-atmosphere interaction were uncovered. To analyze the presence of the oscillation of the ITCZ, the following were used: precipitation series, the meridional component of wind, sea surface temperature (SST), relative humidity, atmospheric pressure and air temperature of the port of Buenaventura; the most influenced sector in Colombia. The data used for the study of the ENSO included the SST anomalies of the regions: Niño 1+2, Niño 3.4, and the Southern Oscillation Index. We conclude that green coffee production in Colombia is more influenced by the migration of the ITCZ than the ENSO.

Keywords : El Niño Southern Oscillation; Intertropical Convergence Zone; Colombian Pacific Basin; Port of Buenaventura.
