In the Pacific Ocean continues during La Nada

September 11, 2013. Scientists from the Climate Prediction Center of the National Meteorological Service of the United States argue that in the past 16 months in the Pacific Ocean there is a phenomenon known as La Nada (La Nada).

This pattern makes it difficult to long-term climate forecasts, climate scientists complain. However, the respite is not to wait until the spring of 2014, scientists sigh.

Experts have learned to make long-term forecasts on the basis of data on variations in temperature of the surface water in the equatorial Pacific Ocean (a phenomenon known as El Niño) and anomalous lowering surface temperatures in the central and eastern tropical Pacific (La Niña). La Nada — an intermediate state of the ocean, which makes it difficult to predict climate change.

"It's like driving a car without the normal map", — said NASA researcher Bill Pattsert.

Scientists also point to the fact that it is the conditions of La Nada implemented mostly in the Pacific Ocean over the past decades: on La Nadu accounts for 50 percent of the years, and El-Ninyu and La Ninyu only 20 and 30 percent, respectively. For a pattern of La Nada typically appear as a very wet and very dry winters, experts note.
