Las corrientes superficiales de chorro del Chocó y el Caribe durante los eventos de El Niño y El Niño Modoki

The objective of this paper was to analyze the influence of two types of El Nino events (known as Canonical and Modoki) on the Choco and the Caribbean low-level jets, which are important moisture transport and precipitation generation mechanisms in Colombia. We explored the influence of these types of El Nino events on these low-level jets by analyzing the differences between climatological features of these jets and the patterns observed during the occurrence of these two El Nino events, as well as the correlations between these phenomena. Our results indicated that for the first half of the year, the strength of these low-level jets diminished during the occurrence of both types of events, while in the last half of the year opposite effects were observed, with the strengthening of the Caribbean low-level jet and the weakening of the Choco jet during the occurrence of both events. However, the magnitude of the impacts observed during Canonical El Nino events was larger than during El Nino Modoki events.
