La Nina is considered to be the counterpart to El Nino, which is characterized by unusually warm ocean temperatures in the equatorial region of the Pacific Ocean. This occurs when the easterly trade winds become weaker and in some cases blows in the opposite direction. This phenomenon has widespread effects on the weather. This causes elevated fire conditions and the Southeast drought conditions. On the other hand, the Pacific Northwest becomes wetter than normal and the Northeast experiences very cold conditions. Both terms refer to large-scale changes in sea-surface temperature across the eastern tropical Pacific.

This naturally occurring phenomenon involves fluctuating ocean temperatures in the central and eastern equatorial Pacific, coupled with changes in the atmosphere. Scientific progress on the understanding and modelling of this phenomenon has improved prediction skills to within a range of one to nine months in advance, giving society the opportunity to prepare for associated hazards such as heavy rains, floods and drought. However, it was not until February that some atmospheric indicators reacted to these warmer than average sea surface temperatures. National Meteorological and Hydrological Services will continue to closely monitor changes in the state of ENSO over the coming months. In summary:. The state of ENSO will continue to be carefully monitored. More detailed interpretations of regional climate variability will be generated routinely by the climate forecasting community over the coming months and will be made available through National Meteorological and Hydrological Services.

It has extensive effects on the weather across the globe, particularly in North America , even affecting the Atlantic and Pacific hurricane seasons. This was followed by a neutral period between and As a result, tied with for the eleventh-warmest year on record. It was the second-coolest year of the 21st century to date, and tied with the second-warmest year of the 20th century. The globally-averaged precipitation over land was the second-wettest year on record, behind Precipitation varied greatly across the globe. It also caused heavy rains over Malaysia , the Philippines , and Indonesia.

What is La Nina?

Tisdale pointed out that the establishment view is that rising greenhouse gas concentrations over time cause a steadily increasing forcing that tends to drive earth temperatures upward. Also during this period, the earth warmed significantly. The earth warmed rapidly during this period from to In fact, about half the warming of the 20th century occurred during those 23 years. When they are balanced, the earth tends to remain at a constant average temperature.

This name was used for the tendency of the phenomenon to arrive around Christmas. Very simplified one can say:. This map shows the development of the Pacific Ocean's surface water temperatures in the last 12 weeks. The Philippines can be found on the extreme left side of the map. An ocean temperature of
