Which of the following weather patterns would be characteristic of a la niña event?

b. high ocean surface temperatures.
c. warm and dry weather in the southern u. s.
d. ocean surface waters moving from west to east.

c. warm and dry weather in the southern U.S.

Explanation:

La Niña is a weather pattern that occurs in the Pacific Ocean, in which strong winds blow warm water to the surface from South America to Indonesia in the western pacific, and as the water moves, cold water rises in south america.

The movement is from the east part of the western pacific to the west part, so answer c and d are wrong.

La Niña has cold ocean temperatures, so b is wrong.

The correct answer is:

c. warm and dry weather in the southern U.S.
