El Niño vs. La Niña

When I was in second grade, which it were the years of nineteen-ninety seven and nineteen-ninety eight, I experience El Niño. For two months in Newport Beach, California there was rain. There was a heavy rainfall of about twelve inches. As my school was by the beach most sea level rooms were flooded. During El Niño all we did was stay inside & played board games. There were periods when the rain would stop and then in the night the rain would start again.

 El Niño is a change in the wind direction. Air pressure differences in India the pressure is lower and high at the date line. El Niño is known as the Southern oscillation. During the El Niño, the trade winds weaken. The sea surface temperature raises well above long term averages over the central eastern tropical pacific. These areas will have heavy rain shifting from the western into the central tropical pacific. El Niño is the warm phase of the tropical atmosphere/ocean interaction. El Niño influences the prevailing circulation of the atmosphere in middle latitudes mostly in the winter. There are significant pacific surfaces temperature changes as well as atmosphere. Ocean circulations patterns change and collapse important Southern American fisheries. El Niño begins when the air pressure gradient of the tropical pacific starts to weaken. The air pressure falls over the eastern tropical pacific and rises over the western pacific. The warm surface of water will slowly drift eastward over the tropical pacific. Anomalies for El Niño are normally between two to three Celsius degrees below the long term average. As El Niño affects the Pacific Ocean, the Atlantic Ocean is experiencing La Niña.

            In contrast, La Niña is the cold phase of the tropical atmosphere/ocean interaction. The air pressure differences high in India and low in the date line. La Niña the northern oscillation. In addition, the trade winds during La Niña are extremely strong across the tropical pacific with low sea surface temperatures, which are lower than usual, and the central and eastern tropical pacific. In the eastern tropical pacific, there are strong trade winds and upwelling.
