The World Meteorological Organization is calling on governments to protect radio frequencies allocated to Earth observation services which are vital for weather forecasts and long-term climate change monitoring. Decisions with major repercussions for Earth exploration, environmental monitoring and meteorological satellite operation will be made at the World Radiocommunication Conference from 28 October – 22 November 2019.

A strong El Niño event during 2019 appears unlikely, according to a new World Meteorological Organization Update, which is based on forecast models and expert opinion from around the globe. Sea surface temperatures in the tropical Pacific Ocean have been at borderline to weak El Niño levels in April and early May 2019. Some El Niño-like atmospheric patterns have also been present.

There is a 50-60% chance of El Niño developing by May 2019, although it is not expected to be a strong event, according to the latest update from the World Meteorological Organization (WMO). Sea surface temperatures in the tropical Pacific were at or slightly below El Niño thresholds in January and early February 2019. Some El Niño-like atmospheric patterns also emerged around late January.

The powerful 2015-2016 El Niño has passed its peak but remains strong and will continue to influence the global climate, according to the latest update from the World Meteorological Organization. It is expected to weaken in the coming months and fade away during the second quarter of 2016. Eastern and central tropical Pacific Ocean surface temperatures were more than 2 degrees Celsius above average in late 2015, providing evidence that the 2015-16 El Niño is one of the strongest on record, comparable with the 1997-98 and 1982-83 events. It is too early to establish conclusively whether it was...

A World Meteorological Organization expert committee has established a new world record significant wave height of 19 meters (62.3 feet) measured by a buoy in the North Atlantic. The wave was recorded by an automated buoy at 0600 UTC on 4 February 2013 in the North Atlantic ocean between Iceland and the United Kingdom (approximately 59° N, 11° W). It followed the passage of a very strong cold front, which produced winds of up to 43.8 knots (50.4 miles per hour) over the area.
