科威特油井大火和菲律宾及日本火山爆发对气候影响的敏感性试验

A NUMERICAL EXPERIMENT OF CLIMATIC EFFECTS FROM BURNING OIL WELLS IN KUWAIT AND EXPLODING VOLCANOES IN PHILIPPINES AND JAPAN

用全球大气环流模式耦合全球混合层海洋与海冰模式研究科威特石油大火和菲律宾及日本火山爆发对大气环流和天气的影响,试验中考虑烟尘在大气辐射平衡过程中的作用。烟尘试验和控制试验均取1991年2月28日初始场,两个试验各计算6个月。试验结果表明,烟尘对烟源当地及邻近地区的气候有明显的影响,对较远地区虽有影响,但一般是较为复杂的关系;本试验没有发现它们对当年的海温异常及中国当年夏季的洪水有直接的影响。

With an AGCM/mixed-layer ocean model,a numerical experiment to investigate the effectsof Kuwait oil fire and volcanoes in Philippines and Japan on atmospheric general circulation andweather is carried on.The role of smokes in atmospheric radiation balance process is introduced inthe smoke sensitive experiment.Control and smoke experiments are run for six months,respec-tively.It is shown from the simulations that the effects of smoke on the climate are significant nearthe smoke sources,and quite weak-and-indirect in the distant areas.In the experiment,it is notfound that the smoke had a significant effect on SST anomaly and flood in Huaihe River Valleyof China in the spring and summer season,1991.
