they observed how the water would become warmer.
the fish would be driven away and the fishermen would catch lesser fish.
farmers would get more profuse crops.
The full name they used was El Nino de Navidad, because El Nino typically peaks around December. El Nino means Little Boy, or Christ Child in spanish.
The farmers get more abundant crops during El Nino because more inland rainfall lead to profuse crop harvest.
The fisherman get less catch during El Nino because the thickness of the eastern pacific ocean increases, preventing water that’s rich in nutrients or cold to reach the surface. this dampened the primary production that the fish depended on.
El Nino gives South America a cooler and wetter winter season.
Southeast Asia typically gets drier-than-average rainfall conditions and Australia typically gets warmer than average weather in the daytime ( caused by a decrease in cloud cover ).
Contrasting to the conditions to South America during this period, El Nino causes North America warmer and drier conditions.
