There is a 75-80% chance of an El Niño developing by February 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 are already at weak El Niño levels in part of the tropical Pacific, although the corresponding atmospheric patterns have not yet materialized.

Weather is a key factor determining the success of the Winter Games. The next Winter Olympic Games will take place from 4 to 20 February 2022, in the municipality of Beijing and the neighbouring Hebei province, in China. The Paralympic Games will follow a month later, from 4 to 13 March. The scheduling of the outdoor events for the Games will rely on very short-term forecasting and nowcasting.

A concerted campaign to boost weather, ice and atmospheric observations in some of the most remote and inhospitable parts on Earth started this week, with the launch of a three-month Special Observing Period in the Antarctic. With days getting longer, the summer is about to start on the Antarctic continent. November is the month when the austral field season begins. This summer, extra atmospheric and sea-ice measurements in addition to the routine observations will be carried out as a contribution to the Year of Polar Prediction (YOPP).

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...

Current Situation and Outlook During the second half of 2016, tropical Pacific Ocean surface temperatures were at borderline weak La Niña/cool-neutral levels. Many atmospheric ENSO indicators also approached or exceeded...

The World Meteorological Organization (WMO) has released its new, long-awaited, digitized International Cloud Atlas – the global reference for observing and identifying clouds, which are an essential part of weather, the climate system and the water cycle. It was released for World Meteorological Day on 23rd March.

A concerted international campaign to improve predictions of weather, climate and ice conditions in the Arctic and Antarctic has been launched to minimize the environmental risks and maximize the opportunities associated with rapid climate change in polar regions and to close the current gaps in polar forecasting capacity. The Year of Polar Prediction takes place from mid-2017 to mid-2019 in order to cover an entire year in both the Arctic and Antarctic and involves the World Meteorological Organization (WMO), Germany’s Alfred Wegener Institute (AWI) and a wide array of partners around the...

Sea surface temperatures in the eastern tropical Pacific Ocean have recently cooled to weak La Niña levels. Similarly, most atmospheric indicators are now consistent with the early stages of a La Niña event. Climate models indicate that weak La Niña conditions are likely to persist into the first quarter of 2018. A return to ENSO-neutral conditions before early 2018 is less likely, while the emergence of El Niño before the second quarter of 2018 appears very remote. National Meteorological and Hydrological Services will continue to closely monitor changes in the state of ENSO over the coming...
