1990–1995 El Niño events

Between 1990 and 1995, the Pacific Ocean experienced various atmospheric and oceanic features, which were consistent with an El Niño event.

Beginning in early 1991, a moderate-to-strong Central Pacific based El Niño developed. From there, the event lasted from most of 1991 until about late spring or summer 1992. The ENSO Modoki event caused global cooling in both 1991 and 1992.

In late summer 1992, not long after the event faded, the Pacific Ocean went under ENSO neutral conditions.

Fall 1992 and the winter of 1992--1993 turned very wet for the Great Plains and the Midwestern United States. The rainfall and snowfall overall during the period were higher than usual. Making matters worse, another Central Pacific El Niño developed in spring 1993. In particular, the severe flooding in 1993 caused $15 billion to just under $17 billion in damage and killed almost fifty people. Furthermore, 1993 was one of the wettest years to happen for the Midwestern United States and the Great Plains.

The following year, 1994, was when yet another El Niño developed during mid-spring and lasted until almost the autumn.

In the Pacific, after 1994's El Niño had faded, the Pacific Ocean was once again ENSO neutral (there is speculation which says the period might have been borderline El Niño although not warm enough for an actual such event). Following the neutral pattern during the winter season of 1994–95 into the spring of 1995, a weak La Niña, which would last from 1995 until the first three quarters of 1996, began developing in the Pacific.
