During the ENSO cycle, in the Nino 3.4 monitoring region of the Equatorial Pacific, the typical sea surface temperature departure from normal is 6° C or more. a. True
b. False

b. False

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.

answer; they use longitude and latitude and   global grid system; good luck
