El Nino must guard against the "1998 flood disaster" at the end of this year.

Global El Nino phenomenon (data chart)

A mature and powerful El Ni ñ o weather event is expected to peak by the end of this year, according to the latest report on the global El Ni ñ o phenomenon released by the United Nations specialized agency, the World Meteorological Organization, on the 16th. And its intensity is likely to be the same as the strong El Ni ñ o phenomenon in 1997 / 1998.

WMO Secretary General Jarro pointed out at the report press conference that monitoring shows that the sea surface temperature in the east-central tropical Pacific has been 2 degrees Celsius higher than normal in the past three months, about 1 degree Celsius above the El Ni ñ o threshold, indicating that El Ni ñ o is at a very significant level. It is predicted that this El Nino will be another strongest El Nino event in the world since the strong El Nino in 1997 and 1998.

The latest WMO report shows that the El Ni ñ o events that have affected the world have shown their power in some areas. Affected by it, many African countries faced the threat of drought in October, and areas such as northern Ethiopia and eastern Sudan faced a serious food crisis. By mid-October, drought in California killed more than 100 million trees, accounting for about 20% of California's forests. In addition, from January to September this year, the global average surface temperature reached its highest level on record, and 2015 is likely to be the hottest year on record. Therefore, the coming winter may become a warm winter due to the influence of El Ni ñ o. In some countries, such as China, the average temperature has already "sent" this signal. The average temperature in October was 11 degrees Celsius, which is 2 to 4 degrees Celsius higher in some areas than in the same period of the year.

Yarro also said that countries have also done a better job in preparing for the El Nino incident than in the past. Based on the recommendations of the national meteorological and hydrological departments, some countries expected to be the most severely affected are deploying plans to focus on the implementation of disaster management strategies in sectors such as agriculture, fisheries, water and sanitation, to save lives and reduce economic loss and damage.

El Ni ñ o phenomenon refers to the phenomenon that the sea water temperature continues to rise abnormally in a large area of the equatorial Middle East Pacific Ocean. It often causes climate anomalies in many parts of the world. Historically, mature El Ni ñ o events usually reached their maximum intensity from October to January of the following year, persisted for most of the first quarter of the following year, and then gradually weakened.
