Which natural event periodically weakens western surface ocean currents in the equatorial pacific ocean, resulting in a change in air temperature and precipitation patterns in the united states?

El Niño is a natural event that periodically weakens the western surface of ocean currents in the equatorial pacific ocean. In an El Niño, the wind that pushes water around (which keeps the east warm and west cold) gets weaker making the ocean warmer, changing the air temperature and precipitation patterns in the United States.

The natural event that weakens the western surface ocean currents in the equatorial Pacific ocean is the EL NINO EVENT.

Explanation:

During this event, the easterly trade winds which converge which converge across the equatorial Pacific Ocean, weakens. Due to this reason the ocean current that draws the surface water away from the western coast of South America slows down. This results in precipitation in the southern part America while the northern part remains dry.  

the proximity of water was an advantage to western europe and its culture was able to flourish as a result. trade and travel by sea were easier and safer in historical times.

1. there are no mountains to protect it from the sea

2. and its has wet cool summers and wet, mild winters.

for e2020. the answer would be some directions from the mountain range so we can find mt. whitney. to locate which direction is north, you should use a   compass. this would not only find mt. whitney, but also becuase of this long paragraph you would get points because it's not like anyone actually reads your work becuase once they read the first sentence it sounds dumb enough to not read becuase i'm not good at answering this but the answer is compass for your benefit.

for e2020 ; -;
