随着区域气候模拟研究的不断深入,新一代区域气候模式CWRF因为其优异性能开始被广泛应用。从其对WRF物理过程的改良,模拟区域和侧边界条件的构建,个例模拟研究和与RegCM的模拟对比3个方面介绍CWRF模式在我国的发展与应用概况,说明CWRF在区域气候模拟中的准确性和先进性。探究了CWRF模式在国内的两大发展前景: 一是在CWRF模式中引入更为准确的物理过程参数化方案,并可进行有机组合实现优化集成气候预报;二是把CWRF与全球气候模式嵌套,进行短期气候的业务预报和长期气候变化及其影响的预测评估。梳理和归纳CWRF模式在我国的应用现状,展望CWRF模式本土化的发展趋势,为CWRF模式的使用和研究提供有意义的参考。

关键词: CWRF, 模拟区域和侧边界条件, 区域气候模式

With the development of regional climate simulation, CWRF, the new generation regional climate model, is increasingly used in climate research because of its advanced capability and high skill. The CWRF application in China was introduced from three aspects: its modifications of WRF physics parameterizations, the construction of modeling domain and lateral boundary conditions, the case simulation study and comparison with RegCM, illustrating the accuracy and advantage of CWRF in regional climate simulations. Furthermore, two major CWRF developmental prospects in China were explored: one was to incorporate more accurate physical parameterization schemes and optimized multi-physics ensemble approach; the other was to nest CWRF in GCMs for short-term climate operational forecast and long-term climate change prediction and impact assessment. The status of CWRF applications in China was summarized and the outlook of its further development was pointed out, which provided a meaningful reference for more general research and application.

Key words: CWRF, Modeling domain and lateral boundary conditions, Regional climate model.
