The phenomenon of Nino revolutionizes global average temperatures, both oceanic and atmospheric. Let’s take stock of the current situation of oceanic anomalies as of June 25th.
Analysis of ocean anomalies
The current data of the anomalies in the region El Nino 3.4located in the Central Pacific, have a value of +0.916°C compared to the norm, a sign of a rather weak un Niño, currently still below +1.0°C.
However, the warmest part of the Pacific Ocean remains the eastern one. The sea bordering Peru shows a strong anomaly of +2.44°C.
Anomalies in the North Atlantic
Another significant anomaly concerns the North Atlantic, which has very high temperatures in its eastern zone, from near the coasts of North Africa and Spain to England and Ireland. Instead, the Labrador Current, which flows along the east coast of the United States, is colder than normal.
This anomaly is currently +1.065°C and, despite a slight downward trend, is the highest ever recorded in the last 40 years.
Climate impacts of anomalies
From a climatic point of view, the consequences of these anomalies are not yet fully understood. The most important anomaly is that of the North Atlantic, which poses significant problems for international climatologists, with anomaly peaks of +5°C off the coasts of France and the British Isles.
Cause of anomalies and predictions
The causes of these anomalies are disputed. Certainly, the developing Niño plays a role, but some blame the decline in sulphate dust production by merchant ships on environmental regulations. This dust reflects part of the solar radiation falling on the sea water.
Others, however, speak of a “runaway greenhouse effect” caused by CO2 emissions from human activities. From a climatic point of view, however, the effect on our peninsula is neutral, the summer is relatively calm in terms of temperatures slightly above normal, while rainfall is generally above average.
Forecasts from the BOM, the Australian Center for Meteorological Research, herald the arrival of a “Super El Niño” with surface temperature anomalies more than +3°C above the norm and therefore capable of revolutionizing a large part of the world’s climate.
