what are the advantage of El Niño ?
Answer
Advantages are Fewer hurricanes and other tropical cyclones in the north Atlantic
. Milder winters in southern Canada and the northern continental United States. Replenishment of water supplies in the southwestern U.S. Less disease in some areas due to drier weather (like malaria in southeastern Africa)
ADVANTAGES :
1.)Relief from Extreme Cold/Heat:
Strong El Ninos will typically bring warmer winters to the northern US states, which will be a relief after last winter’s Arctic conditions and polar vortex
2.)Less Damage from weaker Hurricanes/Cylones
tornadoes seem especially numerous during springs and summers of La Nina and lesser in intensity and frequency during El Nino
3.)Evades Drought
El Nino would bring rain, typically double the annual average in southern California and therefore it is commonly referred to El Nino as the ‘great wet hope’.
4.)Increased Commercial Fishing
The changes in temperatures mean a high fishing season for Peruvian fishermen. The fishermen report increased fish presence along the coast line. This attributed to the fact that the waters are a little warmer, and the winds come along with fish food. This attracts more fish to the surface making it easier for the fishermen to fish different types of fish and in plenty.
5.)Increased Rainfall
he low-pressure zones contribute to increased rainfall in the Southeast parts of the world like Southeast Asia in countries like India that benefit from the increased rainfall for agricultural purposes.
6.)Less disease in some areas due to drier weather (like malaria in southeastern Africa)
7.)Replenishment of water supplies in the southwestern U.S.
DISADVANTAGES:
1.)Catastrophic Floods:
Extreme La Niña events are known to cause disastrous floods in northern parts of Australia
2.)Drier Than Normal Conditions
Over the eastern and central Pacific, La Niña is characterized by over normal pressure. This leads to reduced cloud formation and subsequently reduced rainfall in that particular region
3.)Affects the Climate Patterns in Montana
Montana’s spring is known to be cooler and wetter than usual during a typical La Niña event.
4.)Affects Canada’s Weather Cycles
The cooler temperatures associated with La Niña greatly affects the Canadian weather.
5.)Economic Problems Around the Globe
The effects of La Niña are experienced globally. With catastrophic floods, hurricanes and cyclones in countries on the western part of the Pacific and, on the other hand, bushfires and droughts along the west coast of the USA and East Africa, farms are adversely affected, and crops can be produced as expected. This causes food and agricultural produce shortage.
6.)
Drought and dry conditions
7.)Occurrence of Hurricanes, Typhoons, and very cold weather
