Increased sea temperatures in the Pacific along the ocean currents that move heat to the east has raised concerns that the El Nino phenomenon which will occur this year will be the most intense of the past few decades.

This is the conclusion of Dr. Wenju Cai, Weather expert at the Organization for scientific research and industrial Australia (ACSIRO), after studying the data of the U.S. agency responsible for the atmosphere and ocean.



According to Dr. Wenju Cai, abnormal phenomena such as hot air occurred continuously in the past few months. This is called the prerequisite impact, when the system has an overheated atmosphere it will produce a strong El Niño.

Meanwhile, the meteorologist said that the prospect of an El Nino will be confirmed within the next 1-2 months, although predicting strength of this weather phenomenon is very challenging.

Recently, The World Meteorological Organization (WMO) of the UN says the majority of weather forecast models indicate that El Nino could develop in the middle of this year, but it is still too early to assess its strength.

Earlier, the Australian Bureau of Meteorology said on 8/4 their assesment of El Nino in the year 2014 exceeded 70%. The agency is also expected to publish a report on the outlook of the El Nino weather phenomenon on 6/5, and the meteorological agency of Japan will update the forecast in the next few weeks. An El Nino phenomenon with increased intensity raises concerns about the potential negative effects on the production of major agricultural commodities in Asia and Australia.

El Nino is a phenomenon that consists of significant changes in sea surface temperatures in the tropical belt of the Pacific, which occurs every 2-7 years when the trade winds (strong winds blow constantly from the northeast or southeast toward the equator) begin to wane.

Unusual weather phenomenon makes the temperature rise, causing rain storms, flooding and drought…. severely impacting agricultural activities, fisheries and people's lives.

This phenomenon caused each severe droughts in Australia, Indonesia and South America; flooding in Peru and Ecuador; harsh winter conditions in Europe, East Asian monsoons and hurricanes in the Caribbean.
