各位有人懂这个吗。。。。 想不明白。啊。 。

箭头是朝向,原点是该时间的浪高.
箭头是以上北下南左西右东为标准的

不是swell height 是 swell period 。。。难道看不看无所谓的?

What is Swell Period?
Swell period tells us the approximate distance between swell waves. It is defined as the amount of time it takes for two consecutive wave crests to pass a stationary point.
How can Swell Period be used?
Swell period can be used to help to determine onshore wave heights. A longer period results in a more powerful wave, forming a higher face than swell of a similar height but with a shorter period. The exact height and quality of the waves at Bondi Beach will also depend on the contour of the seabed, wind speed and direction.
右上角点HELP....哈哈

基本就是越小,浪越频繁无力
但是越大,浪就会更有力

周6周日都不敢去.....

。。。。。。。周日 还想去外海看看哈哈。

多少秒一个wave,时间短就比较频繁,叠加的也就高,能量越大。反之能量越小。基本上14sec 就很完美了。

当然要配合tide来看

我的理解是间隔时间长的比那些间隔时间下的更有力
还找到一段文章
the swell period is the ammount of time between waves in a set. it is usually measured in the amount of seconds between the peaks of the wave. a longer swell period usually shows a more powerful wave. it will also get a larger face then a wave of similar height with a shorter period. for example depending on the bottom a 5 ft swell with a 13 second period may actually jack up and have a 12 foot face when it hits a reef or sand bar. on the other hand a 7 ft swell with a 8 second period will be smaller even though the original swell is larger. it will also be a weaker wave since there is less water being pushed along by the energy in the water.
同样的浪高如果间隔时间越久,会在岸边拍到礁石的侍候形成更高的浪.
这个误区大家要小心...

就是说周日这个其实不错是吧。。。swell period 越大越好
评论
willyweather的swell水分太大, 基本上50%都不准. 还是看bom的吧
评论
我刚去查了下,并非如此
评论
你说的这个满不错是吧
评论
大的不好?
评论
看下我之前说的,间隔短,浪多,但是浪高和到岸边的浪高基本一样,间隔长,势力大,那个鬼佬的话就是说了5尺的浪,如果间隔13秒,拍到岸边石头上可以达到13高....而同样5尺的浪,如果间隔短,到岸边拍上石头也就5尺.相对浪的力量比较小
我也是GOOGLE查了一会儿.
我个人是觉得间隔太长.会湿身的厉害或者更危险..
反而间隔短,最多当洗脚.
评论
..对的。。小浪最多洗脚 大浪就下去喂鱼了
评论
其实这个数据都是推算出来的,根据风向,潮汐,温度等多项指标预测海水表层移动,而不是说拍到岸上的强弱。越频繁的浪「水下」能量越小,不管顶风顺风,越容易受风的影响而叠加,那么到地矶的浪高就不容小视。一定要注意安全。一般来讲period越大可以说浪头越缓,「水面」下「流」的能量越大,浪高较稳定。不易产生疯狗浪。
