| ## 作业四 [地转流计算][def4] | ||
|
|
||
| ## 作业五 [海浪资料统计分析-施工ing 06\07\2023][def5] | ||
|  | ||
|
|
||
| - 1.利用两月的月平均资料计算北太平洋*6°N-35°N*范围内的地转流，选取**1500db**作为参考零面画出*10db*，*100 db*，*250 db*，*500 db*等四个深度层上的流场和流速 | ||
| - 2.利用上面计算结果，计算北赤道流水体输运（如130°E，8°N-18°N断面），比较讨论两月结果差异，也可进一步比较不同断面的差异 | ||
|
|
||
| ## 作业五 [海浪资料统计分析][def5] | ||
|
|
||
| - 1. 画出波面高度时间序列，利用上跨零点或者下跨零点的方法读取数据资料中的波高、周期等波浪要素，并画图展示。 | ||
| - 2. 画出波高的概率密度分布，并计算给出有效波高和有效波周期 | ||
