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 the West Pacific and East Pacific, which stem from the EL Nino phenomenon.

Overall

, it is clear evidence that the most noticeable coverts are the wind speed and the

ocean

’s temperature, leading to the switch of

weather

patterns in Australia and Peru.

Besides

, in both

conditions

, the Pacific

Ocean

always undergoes a storm with heavy rain. In terms of the West Pacific, in the standard

weather

conditions

,

this

area is dominated by weak

winds

and warm water pushed westward, so Australia is likely to have a severe

weather

event of rain.

By contrast

, under EL Nino

conditions

, the West side tends to witness a significant shift in climate when a warm

ocean

current goes easterly. To illustrate, strong

winds

blow over the Western part and give Australia nice

weather

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

conditions

, cool water and rich nutrients are pushed vertically to the

ocean

's surface by strong trade

winds

.

As a result

, the Eastern part including Peru experiences a warm climate with a large fish population.

However

, there are dramatic changes in the East side’s

weather

which is affected by EL Nino. Specifically, the number of fish sees a sharp decrease since trade

winds

weaken causing seawater to quickly warm up with two separated layers of the warm surface water and the deeper cold one.
