East Asia Seasonal Forecast Verification In November 2018, the World Climate Service began issuing a subjective East Asia seasonal forecast, including China, Japan, the Koreas, India, and Indochina. While the WCS seasonal portal has always provided a comprehensive array of forecasts and analysis tools for the entire globe, the WCS monthly seasonal reports had previously[…]
Introduction Last year at about this time, the World Climate Service highlighted a new effort to develop a statistical forecast capability for the subseasonal time frame (weeks in advance), and last summer a new World Climate Service product was released. Since then, the statistical forecast scheme, known as Sub-R, has been delivering week 3-6 temperature[…]
Indian Ocean Dipole in 2019 The strongly positive phase of the Indian Ocean Dipole (IOD) was one of the most striking features of global climate variability of 2019. The IOD is a mode of coupled ocean-atmosphere variability in the Indian Ocean, and it has strong impacts on climate anomalies in the surrounding areas and farther[…]
Introduction to Seasonal and Subseasonal Probabilistic Forecasts The probabilistic climate forecast is emerging as an important tool for weather-sensitive companies and organizations to gain value from long-range forecasts. The World Climate Service seasonal and subseasonal (S2S) weather forecasts emphasize probabilistic information, which is less intuitive but more powerful than the traditional style of deterministic short-term[…]
A notable late winter cold outbreak over Europe was successfully anticipated by World Climate Service sub-seasonal forecast guidance. Beginning in early January, WCS sub-seasonal outlooks identified a threat of cold at some point in February, and the risk was more clearly defined in subsequent guidance; by early February, confidence was high that a prominent cold[…]
Prescient Weather was honored by the American Meteorological Society at its 2018 annual meeting in Austin, Texas. Prescient Weather, which operates the World Climate Service, was granted the 2018 award for outstanding services to meteorology by a corporation; the citation reads “For scientific creativity and technological innovation in transforming climate data, climate variability predictions, and[…]
