Research activities focusing on high-impact weather – from basic research in the academic community to operational contributions.

Sand and dust storms are common meteorological hazards in arid and semi-arid regions. They are usually caused by thunderstorms – or strong pressure gradients associated with cyclones – which increase wind speed over a wide area. These strong winds lift large amounts of sand and dust from bare, dry soils into the atmosphere, transporting them hundreds to thousands of kilometres away. Some 40% of aerosols in the troposphere (the lowest layer of Earth’s atmosphere) are dust particles from wind erosion.

As atmospheric CO 2 continues to increase, more and more CO 2 enters the ocean, which reduces pH (pH is a measure of acidity, the lower the pH, the more acidic the liquid) in a process referred to as ocean acidification. Declines in surface ocean pH due to ocean acidification are already detectable and accelerating.

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.

The climate science community can play an important role in addressing public health challenges. Many human diseases and health conditions are sensitive to changes in temperature, precipitation, humidity, wind and other environmental conditions such as air and water quality. Climate information can thus be used as a sign of risk and to inform disease monitoring and health research. In some cases, it can be used to predict when and where disease outbreaks may occur, in relation to expected climate conditions.

The second session of the Pan-Arctic Climate Outlook Forum (PARCOF-2) was held virtually on 30 October 2018 to review the climate conditions during the previous summer season, and to provide outlook for the forthcoming winter season.

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.
