Answer:
b. False
Step-by-step explanation:
During the ENSO cycle, in the Nino 3.4 monitoring region of the Equatorial Pacific, the variation in normal sea surface temperature is 3 ° C or less. This is because in the tropical pacific the surface water varies between 1 - 3ºC, which makes it impossible for the typical variation of the normal sea surface temperature to be 6 ° C or more.
