Climate prediction system

Abstract

The invention discloses a climate prediction system, which is characterized by comprising the observation data; a data assimilation system; a climate model operation subsystem; a prediction subsystem;a product subsystem; and a high-performance computer. The data assimilation system comprises a data assimilation and support subsystem; the climate model operation subsystem comprises a global general circulation model, a global ocean circulation model, a high-resolution East Asian regional climate model and a simplified ENSO prediction model. The prediction subsystem comprises a prediction correction and detection subsystem; the product subsystem comprises a product generation and distribution subsystem, wherein the coupling of the global atmospheric circulation model and the global ocean circulation model constitutes an air-sea coupled model. By combining the statistical method with the dynamic method, and combining the multiple initial values with the multiple models, the climate prediction system has the advantages of long prediction time, high accuracy, fast computation speed and strong regional pertinence.

Description

technical field [0001] The present invention relates to the technical field of climate, and more specifically relates to a climate prediction system. Background technique [0002] In recent years, unprecedented attention has been paid to climate prediction research at home and abroad. Climate prediction research not only has important social and economic significance, but also has important scientific value. It is one of the science and technology fields that are prioritized by various countries. Short-term climate prediction has its solid scientific foundation. Currently, short-term climate prediction systems based on this scientific basis have shown certain prediction skills. However, short-term climate prediction systems have short prediction time, low accuracy, and computational speed. Slow, and regional specificity and other issues. [0003] Therefore, how to provide a prediction that can realize the year, month and day, and the accuracy rate can be about 10% higher t...
