Using latitude and longitude is easiest along the equator, where the grid lines formed are roughly square.
沿着赤道使用维度和经度相当简单，形成的网格线大致也是方形的。

We have achieved the parallelization by extracting the analysis boxes and model grid point latitude rows with leaped step and distributing data to different processors.
该算法通过间隔选取分析盒子和模式格点纬圈行，将数据分配给不同的处理机实现分布式并行。
