The phenomenon "El Niño robust" will bring more calimas and less trade winds to Fuerteventura this 2023 and in 2024.
It is one of the great Weather patterns of the planet's surface atmospheric system and has a significant impact on the global climate.
The temperature changes that occur in the waters of the Pacific have an impact on the climatology of the entire planet. During this month of April begins to occur, as expected, a phase change in the oscillation called "el niño-southern oscillation", or ENSO in its acronym in English.
It is an oscillation in the temperatures of the surface and deep waters of the tropical zone of the central and eastern Pacific Ocean that has two phases. During the positive phase the warm waters of this area move westward and accumulate off the coast of South America, altering the atmospheric circulation, during the negative phase, known as "La Niña", an anomalous cooling of the sea surface occurs.
During the last years the phenomenon that has accompanied us is that of La niña, but at the moment the oscillation is moving to neutral phase and according to predictions it begins to change to the positive phase.
According to all predictions it is more than likely that this positive phase is more intense than usual and approaches 2ºC of anomaly in the months of September and October, this is what is known as "the intense or robust child".
Main effects of El Niño at the planetary level
The most important effects that the positive phase of ENSO has had on the global climate are, among others, the decrease in cyclonic activity in the Atlantic and the intensification of cycles in the eastern Pacific, the decrease in rainfall in Southeast Asia and Australia and the increase in rainfall in South America.
In addition, the positive phase of ENSO also has effects on fisheries and agriculture in different parts of the world.
Main known effects of "El Niño" in the Canary Islands
In the Canary Islands the air temperature increases and the total rainfall decreases. In addition, there is a decrease in the intensity of the trade winds and an increase in the frequency of Saharan advection episodes, which can especially affect ocean surface temperatures in the region and air quality and visibility respectively.
