The theme for this years World Meteorological Day, “Climate knowledge for climate action,” provides an opportunity to take stock of the climate knowledge built in the last decades as an essential base to The Abisko Field Station in Sweden will host the Polar Prediction School support the path towards more ambitious action to address climate change and climate variability.
Weather forecasts have been a part of everyday life since the mid twentieth century. Before going to work or school, people check the weather in order to know how to dress and how to keep safe. Weather forecasts help farmers, emergency workers and other decisionmakers in weather-sensitive sectors to schedule their daily and weekly work priorities. These forecasts are becoming ever more reliable – today’s five-day weather forecast is as good as the two-day forecast of 25 years ago – thanks to advances in weather and climate science and in computing power.

Researchers are using improved observations and greater computing power to study and predict natural cycles and broader patterns in the climate system. As a result, they can provide increasingly useful seasonal climate predictions. While the science progresses every year, a great deal is also being learned about how to help decisionmakers understand and apply climate knowledge. This enables the providers of weather and climate knowledge to develop and offer customized information for a wide range of users.
