WE , the Ministers responsible for meteorology in Africa, meeting virtually for the fifth session of the African Ministerial Conference on Meteorology (AMCOMET) on 17 March 2021: (…) Note with...
When it comes to the weather and climate, most of us think only about what is happening in the atmosphere. If we ignore the ocean, however, we miss a big piece of the picture: covering some 70% of the Earth’s surface, the ocean is a major driver of the world’s weather and climate.
Regional Climate Outlook Forums (RCOFs) produce consensus-based, user-relevant climate outlook products in real time through regional cooperation and partnership in order to reduce climate-related risks and support sustainable development for the coming season in sectors of critical socioeconomic significance for the region in question.
The impact of aerosols on the atmosphere is widely acknowledged as one of the most significant and uncertain aspects of climate change projections. The observed global warming trend is considerably less than expected from the increase in greenhouse gases, and much of the difference can be explained by aerosol effects. Aerosols impact climate through direct scattering and absorption of incoming solar radiation and trapping of outgoing long-wave radiation as well as through alteration of cloud optical properties and the formation of clouds and precipitation.
Global-scale seasonal forecasts, including those of precipitation and surface temperature, are routinely produced by WMO-accredited centres using sophisticated atmosphere-ocean coupled models, which take into account ENSO as well as other...

Climate describes the average weather conditions for a particular location and over a long period of time. We study the climate, its variations and extremes, and its influences on a variety of activities including human health, safety and welfare to support evidence-based decision-making on how to best adapt to a changing climate.
