The warm and cold events in the Tropical North Atlantic (6-22°N, 15-80°W) region are quantified using sea surface temperature (SST) normalized indices. A warm (cold) event was defined if the 5-month running mean index was above (below) the fourth (second) quintile for six or more months. The event occurrence was non-periodic and the durations showed great variability. Warm events occur 17% of the time and cold events occur 15.5% of the time. It was noticed that in general warm and cold events tend to begin during the first semester of the year and end during the second semester.
