This work presents the study of the influence of global fields of Sea Level Pressure (SLP) and Sea Surface Temperature (SST), as well as the impact of various climatic indices of Teleconnections (NAO, PDO, NIÑO 3.4, etc.) on the air temperature in Colombia. To this end, previously, the main modes of variability of air temperature for winter (DJF) and summer (JJA) seasons in the country have been identified using principal component analysis (PCA). The results show a significant influence of the SLP and the SST from the Pacific, essentially associated with the ENSO, and from the tropical Atlantic, more significant for winter temperatures than for summer. Because of the relationships found between the global patterns and the Colombia temperatures are not in phase, showing important correlations several seasons in advance, the results obtained from this study could be very useful for the prediction of temperatures in Colombia.
