Question

question: how do el niño weather patterns affect precipitation in the southern portion of the united states? answer options: select one of four more precipitation during el niño years no way to predict precipitation changes less precipitation during el niño years mainly snow precipitation instead of rain

Explanation:

El Niño is a climate pattern where warm ocean waters in the Pacific affect global weather. In the southern US, El Niño typically brings increased precipitation (rainfall) due to altered atmospheric circulation patterns that direct more moisture - laden air to the region. The option "No way to predict precipitation changes" is incorrect as there are established patterns. "Less precipitation during El Niño years" is the opposite of what occurs. "Mainly snow precipitation instead of rain" is also incorrect as El Niño in the southern US is associated with more rain, not a shift to mainly snow.

Answer:

A. More precipitation during El Niño years
