CPT+ is designed to generate seasonal and sub-seasonal forecasts using global weather and climate model predictions as inputs, or using purely empirical methods. It is specifically designed for operational forecasting, but can also be used in research. CPT+ has more than 2500 registered users, including at national forecasting centres throughout the Caribbean, Central and South America, in much of Africa, and parts of Asia.
