摘　　要：本文探讨了将高空西风指数的预报值应用于气象导航的方法。首先利用北太平洋上空500Hpa历史天气图和对应时期的海浪实况数据,制作出不同高空天气型下的波浪分布模型,然后根据这些波浪模型计算出不同高空天气型下的初始推荐航线,并建立推荐航线数据库,以便在实际导航中从中选出适当的航线推荐给船舶。最后,利用波浪实况进行了55次模拟航行,结果表明本文所提出的方法是可行的。This paper discusses a weather routing method based on the forecasts of zonal index. First, an analysis is made of the upper-air 500Hpa weather charts and wave chants of the North Pacific Ocean (1973-1983), and thewave distribution models in different upper-air patterns are produced. Then, by applying these models, the initial recommended routing is calculated, which can be proposed to ships aceording to environmental conditions. Finally, 55 voyage simulations are made with the wave data, the result of which shows tibet the above method is reliable.
