Weather phenomena

One of the most well-known weather phenomena is El Nino. This type of weather phenomenon is said to be well known because of its unknown origins and unpredictable occurrence. There are different explanations as to what El Nino does to the weather patterns all over the world. This phenomenon is known not only to alter weather conditions in affected areas but also affect the lives of people. The El Nino phenomenon is described as the widespread warming of the ocean temperatures especially in the central and eastern pacific (“Australian Government: Bureau of Meteorology”).

In El Nino, weather is disrupted because there is a decline in the amount of exchange of winds, therefore reducing the amount of cool water and is replaced by the warm waters (Reynolds et al. ). Scientists until know could not identify the exact reason why this phenomenon occurs and in fact they can never find out how such phenomenon works (“Solve Your Problem”). Though this may be an unpredictable phenomenon, this is said to be a natural condition that the tropical pacific region experiences (Reynolds et al. ).

It may be a natural weather condition that mostly is experienced by the tropical pacific regions, but the effects and its unpredictability makes it more of a threat. The phenomenon El Nino is known for its effects not only in the alteration of weather but also in ruining the lives of many people. El Nino is known as an “oscillation of the ocean atmosphere” (“NOAA/PMEL/TAO: The El Nino story”) where its effects would be alteration of weather all over the world. El Nino alters weather conditions not only of the tropical pacific region, but eventually the weather conditions of the entire globe (Suplee).

Most common weather alteration caused by El Nino is the increase in rainfall; more rainfall means flood (“NOAA/PMEL/TAO: The El Nino story”). Not only does altering weathers all over the globe is one effect of El Nino, but the most common side effect is drought. Because of the abnormality in the exchange of winds and the extreme temperature it brings, drought is experienced by countries affected by El Nino. Most of the people that would be affected by drought are farmers. Drought brings disasters to the crops of farmers and therefore crippling their means of livelihood.

Not only does drought bring about the devastation of crops, it also brings about drying of rivers and lakes. Because of extreme hot weather brought about by the warm surface sea water, most rivers dry up; this event affects the supply of water to people and animals that rely on these streams. It is evident that this phenomenon is one factor that could contribute other issues, most specifically changes in climate. The El Nino phenomenon could last for several months, and after a few seasons, a cycle of cooling back the ocean comes and the phenomenon La Nina occurs (Reynolds et al).

The La Nina phenomenon is another cycle of the cooling of the ocean seas. La Nina occurs when some of the warm temperatures given off by El Nino give way to the formation of unusual strong winds and cold temperatures of the surface water (Reynolds et al. ). Though La Nina is commonly known to occur after El Nino, now this cold phenomenon is as much unpredictable as El Nino (Suplee). Most of the known effects of La Nina are heavy rains. During La Nina season, rainfalls are much heavier.

The increase in the rainfall during this season is caused by the interaction between the warm water left by El Nino and the now forming cold waters from La Nina (Suplee). Because of this reaction, heavy monsoon rains and higher precipitations are felt by regions in the tropical pacific (Suplee). Hurricanes that occur during La Nina seasons are said to be the deadliest of them all (Suplee). It could clearly be seen that the La Nina phenomenon relies on what happens during the El Nino season, meaning it is during this season that we feel the after effect of the season El Nino.

Though El Nino and La Nina are a contradicting phenomenon, both contribute to the alteration of the usual climates that people are experiencing. These seasons bring about more than just hot and cold weather; they also dictate the type of climates people will experience in the coming days.
