在海域面积不大的情况上,划分为0.5度的方格区),对何个方格,从气候资料中抄入关于风、浪、流的月平均数据,尔后,在平面图上的标准航路左右画出若干条任意航线,在其中每条航线上估算船在浪中的失速和海流的影响。最后,再通过比较确认,哪条航路所要求花费的航渡时间最短,它就是船 In the case of small area of ​​the sea, divided into 0.5 degree grid area), for which square, from the climatological data into the monthly average wind, wave and flow data, then, in the plane on the standard route Draw a number of arbitrary routes to the left and right, and estimate the effects of ship stalls and currents in each of these routes. Finally, by comparing to confirm which routes require the shortest flight time, it is the ship
