Abstract: As a necessary component of the seamless weather and climate forecast system, the 10-30 day extended-range forecast plays a crucial role in disaster prevention and mitigation as well as in meteorological services for various industries. Since 2002, the operational extended-range forecast has been explored from multiple aspects in China. However, because of the limitation in forecast methods and techniques, the shortage of the specialist team and the incomplete forecast system, the current extendedrange forecast cannot satisfy the demand of meteorological service. Through literature review, questionnaire and interview with experts, this study compares and analyzes the current states of operational extended-range forecast, specialist team and collaborative system and mechanism in China and at abroad, puts forward the possible factors restricting the further development of extended-range forecast in China, and offers several improvement measures. This study provides scientific support and basis for the decision-making of operational extended-range forecast.
