ENSO La Niña periods promote rather drought conditions in the South Pacific.El Niño – Easy explained You are not a scientist and need a simple explanation to grasp it? Watch this funny video of the climate crab and you understand the impacts of El Niño on the Pacific Island region: Water scarcity in La Niña periods In La Niña periods many islands experience situations of water shortage.The main concepts of El Nino are very simple and there are many variations, causes, affects, and relationships to study.
El Nino and La Nina are unusual weather patterns that form in the period of 10 months.
El Nino and La Nina both impact climates all around the world, each different in countries and regions.
Meteorologists discovered in the late 19th century that El Nino weather events appeared to be occurring approximately every ten to fifteen years but in the late 19th century this gradually changed to a strong pulse of about three years by the early 20th century, at the same time it had been noted that the temperature was rising above the average....
[tags: Climate Change, Greenhouse Gases] - El Nino This morning, before writing this essay, I spent a considerable amount of time watering my wilting garden. Why are we suffering such severe weather this summer.
Mayell (1997) discussed how fishermen from Peru wondered why in certain years the normally cold water would become warm and the flow would reverse in an opposite direction.
The change in water temperature would kill the majority of the fish and thus cause major problems for fishermen and many others who relied on fish.
This makes the islands very vulnerable to variations of precipitation patterns.
How climate change affects ENSO Climate change model projections show that ENSO events are becoming more intense and extreme with longer periods of drought and more frequent tropical cyclones.
It is defined as lack of sufficient access to safe and affordable water for drinking, washing and livelihood.
Since Pacific islands are poorly gifted with surface water and groundwater is too brackish to drink, many countries dependent on rainwater as primary water source.
