A simulation calculation was made by the Simpson numerical integral, and the simulated results of the initial course and route distance were compared with those based on the great circle route.

用辛普森自适应算法进行了仿真计算，并与大圆航线的计算结果进行了比较。

It can motivate about 3 pairs of waves that propagate along a "great circle route" and significantly affect the general circulation in mid-high latitudes.

它能激发大约3对波动，这些波动主要沿“大圆路径”传播，对中高纬的环流形势有重要影响。

The analysis indicates that the conditions of second derivative of the above relevant factors play an important role in the formation of great circle route.

本文研究表明，上述影响因素的二阶经向变率的存在条件对于“大圆路径”形成起了重要作用。

This lack of maritime surveillance and disaster preparedness is not unique to the great circle route, but the nasty local conditions are.

ECONOMIST: Shipwrecks in the Aleutians

The archipelago is a hazardous traffic median in the great circle route, the shortest path between ports on either side of the North Pacific.
