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...

World Meteorological Organization initiatives to strengthen observations and predictions of weather, climate and ice conditions in response to rapid climate change in the Polar regions were showcased at the Arctic Circle Assembly in Iceland. WMO Secretary-General Petteri Taalas joined leading global experts at a plenary session on Observing and Responding to a Changing Arctic on the opening day of the assembly on 13 October.

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...

Senior representatives of the World Meteorological Organization and World Climate Research Programme joined scientists meeting at the UN Climate Change Conference in Bonn in warning of accelerating global climate impacts and called for more and better regional observation to help local populations build resilience to climate change with the help of more precise forecasts and modeling. This is particularly important given the fact that the current global average temperature is affecting different regions in different ways. While global climate models provide important projections, they...

Recognizing that expanded and improved observations now make possible a broader assessment of global atmospheric chemistry, the WMO Global Atmosphere Watch programme has published a new report on global and regional trends in reactive gases. This group of gases includes such chemicals as surface ozone, nitrogen oxides, carbon monoxide, sulfur dioxide, and volatile organic compounds, many of which are considered to be harmful pollutants. The first issue of the Reactive Gases Bulletin reviews long-term observation data on volatile organic compounds (VOCs) and discusses past and recent trends....

A new era in satellite meteorology offers unprecedented opportunities to improve Earth observations and understanding, but also poses big challenges for users worldwide. A top-level World Meteorological Organization delegation outlined WMO’s strategic perspectives at the US National Oceanic and Atmospheric Administration Satellite Conference 2017 . The latest generation of satellites from China, Europe, India, Japan, the Republic of Korea, Russian Federation and the USA and other countries is becoming operational, providing unprecedented advances in weather forecasting, disaster risk...

Managed for most of its life by monks and operated today by MeteoSwiss, the meteorological station at Grand-St-Bernard, located high in the Swiss Alps near the border with Italy, is today celebrating 200 years of uninterrupted meteorological observation. During the ceremony, the World Meteorological Organization presented the station with a certificate and a commemorative metal plate designating it as a Centennial Observing Station. The ceremony was attended by representatives of WMO, MeteoSwiss, the Observatory of Geneva, the canton of Valais, and members of the local monastery.
