Abstract:

利用BOREAS,HEIFE,ARME,GAME-TIPEX等大量的陆面外场观测资料,针对不同类型的陆面过程,对所发展的陆面模式CLSM的性能进行检验.模拟结果与观测资料的对比分析表明:一方面,CLSM能够对积雪变化、干旱/半干旱地区的水热交换等特殊的陆面过程进行合理的描述;另一方面,CLSM对热带雨林地区的植被-大气相互作用、高原地气交换过程同样具有很强的模拟能力.CLSM解决了陆面模式对上述特殊下垫面描述能力有限的实际问题,保证了对特殊下垫面进行合理描述的同时,又保证了对其他不同陆面状况的模拟能力.CLSM改善了陆面模式对全球范围内不同下垫面条件下的陆面过程及地-气交换过程的模拟能力.
