新华社北京一月十八日电(记者张继民)国家海洋局海洋环境预报中心一九八四年先后九次在横跨太平洋的几条航线上,进行了气象导航试验,导航效果已接近国外这类导航的先进水平。 气象导航亦称最佳航线。它根据海洋环境要素预报和船舶本身的运动性能,利用电子计算机模拟大量航线,从中优选出航行安全、航程较短、航时最省、人员舒适及货损最小的理想航线;船舶启航后,实行连续跟踪预报服务,提供航行海域未来的环境状况,如风向、风力、风浪及涌浪等,并结合船只及货载的具体情况修正船舶航向,加速或缓行,借以避难就易,提高营运效益。
Xinhua News Agency, Beijing, January 18 (Reporter Zhang Jimin) The Marine Environment Prediction Center of the State Oceanic Administration carried out meteorological navigation tests on a number of routes across the Pacific for nine times in 1984, and the navigation effect was close to that of foreign countries Class navigation advanced level. Meteorological navigation also known as the best route. Based on the forecast of the marine environment and the movement performance of the ship itself, it uses computers to simulate a large number of routes and selects the ideal route with safe navigation, shorter range, lowest flight time, comfortable crew and minimum cargo damage from the navigation. After the vessel sailed, Continuous tracking and forecasting services provide future environmental conditions in the navigation area, such as wind direction, wind force, storms and swells, and modify the course, speeding up or slowing down of vessels in light of the specific conditions of the vessels and cargoes in order to make evacuation easy and enhance operational efficiency.
