The theme of the 2021 World Meteorological Day highlights the inherent links and long-term cooperation between oceanography and meteorology. Two centuries ago, considerations of the safety of marine navigation were the decisive motivation for calling the first conference on marine meteorological observations. Held on 23 and 25 August 1853 in Brussels, the conference initiated common planning and cooperation between national meteorological offices. During the Crimean War, the Great Balaklava storm...

“What maximum winds are expected in the storm area?” That is one of Standard Marine Communication Phrases under the International Maritime Organization (IMO) that officers in charge of navigation on ships, whatever their nationality, must be able to use and understand in English.

The world’s 60 000 ocean going cargo ships are operated by some 1.6 million seafarers, traversing the globe and carrying 11 billion tons of trade annually which...

Eighty-six countries are involved in ocean observations with about 10 000 in situ ocean observing platforms and 170 satellites continuously monitoring the global ocean and atmosphere. The analyses, forecasts and products based on ocean observations are the bedrock of decisions across a swath of socio-economic sectors, especially in marine transportation, coastal communities, climate, agriculture and ocean health. Society's need for ocean information is increasing. In response, the Global Ocean Observing...

As a meteorologist, I’ve grown quite fond of this quote. I refer to it frequently when I’m explaining to people the tremendous changes that have taken place in the meteorological community in recent years. I think it captures the essence of our growing understanding that weather, water, climate and oceans are all inextricably linked, and so our work as individual meteorological and hydrological agencies, as well as our collaborative work...

http://www.icos-cp.eu/event/917Humanity is going through a health and a related economic crisis due to COVID-19. The impacts of the measures taken by governments are far and wide. The restrictions imposed on population mobility and commercial activities have resulted in changes in anthropogenic emissions and in the atmospheric chemical composition. These changes were especially pronounced in urban areas and observable in air pollutants as well as in greenhouse gases.

There are important dates in every organization’s history – dates to celebrate and to remember achievements and the people behind them. In 2020, we mark the 70th anniversary of the WMO – it is a prelude to an even more important event: the 150th year of the International Meteorological Organization (IMO) and WMO, which will be celebrated by the global meteorological community in 2023. But some question that date as the early foundational events of international cooperation in meteorology are a bit obscure and cited differently in various historic reviews.

Tropical cyclones (typhoons and hurricanes are the same phenomena named differently in different regions) are among the most frequent, frightening and life-threating of natural phenomena. They can generate winds that ravage harvests and tear apart homes and infrastructure, deadly storm surges and torrential downpours that trigger floods and coastal inundations.
