MCQ (Single Correct)

What is the typical duration of an ENSO (EI Nifio-Southern Oscillation) event?

Several days Several weeks Several months Correct Several Years

Temporal Duration of ENSO Events:
An El Niño-Southern Oscillation (ENSO) episode typically develops in the tropical Pacific during boreal spring/summer, reaches peak intensity during late autumn or winter, and dissipates in the following spring, lasting for a typical duration of several months (approximately 9 to 18 months).
Correct Option: Option 3 (Several months).
