La Niña effects on weather conditions in the USA
Sometimes, the surface water of the Central and Eastern Pacific Ocean becomes colder than the normal temperature of the ocean. It is noticed especially around the west coastal areas of South America. People living in Oklahoma will notice more rainfall.
This phenomenon of change in the temperature of the surface water is known as La Niña. La Niña can even cause Tornado in areas like Oklahoma. People may even need to look for storm shelter companies in OKC because the storms caused by La Niña can be really destructive.
Effects of La Niña
The climate is affected greatly by La Niña. From the snow pattern to the rain to even the storm, everything is affected by the same. While some areas receive too much rain, some areas become dry because of this geographical phenomenon.
La Niña may not occur every year. But it is a weather pattern that is quite complex. La Niña can lead to such extreme cold winters in Oklahoma that people may need to contact storm shelter companies. The same La Niña will cause drought in the Southern hemisphere.
The Reason of La Niña Effect
La Niña happens when the east-to-west wind blows the water that is warmer to the west. The wind is pretty much stronger during this time. Hence, it pushes the colder surface water and replaces it with the warm water. The cold water reaches South America due to the constant push. This situation gives rise to storms like tornados that can cause serious devastation. People may need to contact storm shelter companies to keep their families safe.
The situation reverses and causes El Niño to take place. The easterly wind becomes weaker and cannot push the cold water anymore. Also, sometimes, the wind blows in the opposite direction. In this situation, the Southern part of America receives more warmth.
The Temperature of The Sea Surface Water
La Niña can really cause the temperature of the surface water to plummet, which causes the temperature in Pacific Ocean to be 3-5 degrees Celsius or even below that. The temperature in most of the states in America is affected by La Niña. La Niña lasts for around five months in a year in the USA.
The milder but drier winter that is witnessed in the Southern hemisphere is caused by La Niña. The same weather conditions causes drought and even wild fire in these areas. However, during this time, the Pacific Northwest receives more rain and is pretty cold.
