Grads在海浪大数据处理中的优势

The Advantage of Grads Software in Dealing with the Wave Big Data

在信息爆炸的大数据时代,选择高效的应用工具,是从大数据中获取有用信息的重要保证。本文在此利用Grads (Grid Analysis and Display System)软件对海洋数据进行处理、绘图,同时利用其他软件进行对比,发现Grads程序更适合应用于海洋大数据处理,理由如下:1) Grads程序简洁、不易出错,程序简短。2) Grads处理效率明显高于其与软件。还利用Grads软件进行滑动平均、求线性变化趋势、求相关系数、结合Fortran程序统计频率、以及一些常用函数的计算,发现该软件在这些方面都具有非常强大、高效的运算能力、显示能力。在未来的工作中,还可以尝试着将Grads软件应用于海浪以外的其与数据,为海洋建设做贡献。

In the big data times of information explosion, the selection of efficiency software is to get the im-portant guarantee of useful information from big data. In this paper, we use Grads (Grid Analysis and Display System) software to handle and draw the big marine data, at the same time using other software to compare with Grads. The results show that Grads program is more suitable in marine data handling, with following reasons: 1) Grads program is succinct, hardly to make mistakes;2) Grads has advantages in handling efficiency over other software obviously. In addition, based on Grads, by calculating the moving average, linear trend, correlation coefficient, statistical frequency combined with Fortran program and some common used functions, we found that Grads had advantages in these aspects with higher efficient calculating capability and graphic display ability. In future, we can make contributions for oceanic development by using Grads for other data not in ocean wave field.
