El Niño is the name of a warm ocean current that affects weather patterns on both sides of the Pacific Ocean. The diagrams compare normal conditions in the Pacific with El Niño conditions.

The diagrams illustrate the changes in the atmospheric conditions in different parts of the Pacific Ocean namely West Pacific and East Pacific, which stem from EL Nino.

Overall

, It is clear evidence that the most noticeable coverts are the directions of wind and

water

, which cause the switch of

weather

pattern in Australia and Peru. In terms of the West Pacific, in the standard

weather

conditions,

this

area is dominated by weak

winds

and warm

water

, so Australia is likely to have a

weather

pattern of rain.

By contrast

, the West side will witness a significant shift in climate when a warm ocean current goes easterly. To illustrate, strong

winds

are blowing over the Western part and giving Australia nice

weather

with sunny. Regarding the East Pacific, in a typical day of standard

weather

conditions, cool

water

and rich nutrients are pushed vertically to the ocean's surface by strong trade

winds

.

As a result

, Peru experiences a warm climate with a large fish population.

However

, there are dramatic changes in the East side’s

weather

pattern which is affected by EL Nino. Specifically, the number of fish sees a sharp decrease since seawater is separated into two layers with cool

water

flowing underneath warm one which causes the decline of nutrients, and weak

winds

blowing above.
