摘　　要：在美国ＮＭＣＡＧＣＭ模式的基础上，参照ＣＯＬＡ低分辨率ＡＧＣＭ模式，移植和改进了一个包括植被层陆面过程的陆－气耦合全球大气环流谱模式（Ｒ１５Ｌ９）。其水平分辨率为菱形截断１５波，垂直方向分为９层，陆面过程采用简化的简单生物圈模式（ＳＳｉＢ）。该模式改善了对陆面特征的刻画。通过进一步完善初值处理、下垫面边值处理、模式后诊断及图形处理，使其成为一套可用于气候模拟研究的工具。对１月、７月平均场的模拟及其与１月、７月气候平均场的比较表明，该模式的性能良好。Based on the NMC AGCM,a COLA's low resolution global spectral model with the SSiB scheme,R7L9 has been transplanted and developed into the model R15L9. The model,R15L9, is a global spectral model with rhomboidal truncation at zonal wavenumber 15 and 9 sigma layers. The land surface processes adopted the Simplified Simple Biosphere(SSiB) model. The modified model given a better description of the land surface characters. The model can be used as a research tool in the climate modelling through improvements of initial values,underlying surface boudaries,model diagnosis and graph treatment. The averaged climate fields for winter and summer are modeled and the comparison of the simulated results with observations in January and July show that the model can depict the basic atmosphere states and climate characteristics.
