The World Meteorological Organization is thrilled to announce the launch of its 2024 calendar photography competition. It is one of our most eagerly awaited annual activities. Each year becomes even more successful with an ever-increasing number of amazing photographs which illustrate the beauty, power and importance of weather, climate and water.
Our weather and climate and the water cycle know no national or political boundaries. International cooperation is essential. This philosophy has driven the work of the world’s meteorological community since 1873 and will guide us as we translate science into services for society for present and future generations.
Since 1961, the World Meteorological Organization has been celebrating World Meteorological Day with a different theme selected for each year.
