    适用于苹果及安卓系统的航海气象APP测评

                                                                               非常好的气象软件-但也有局限

安卓系统,苹果,气象 适用于苹果及安卓系统的航海气象APP测评 9926056251679a554b.png

航海气象APP(免费,有广告)航海气象正式版(无广告,需接电源)由bluefin工程出品,综合了许多种有关于航行气象APP的有用信息。但也并非全能,对于能很容易的实时了解水上的情况,是一很好的开始,并且它取代了需要去确认另外一些APP或者智能设备所收藏的网页的必要。

即使在水上你没有连通它,在启航前你已经很好的利用它核对了相关的气象数据。警告:此气象软件不保存所下载的数据,所以在海上要想更新数据就必须要保持持续的连通。

版本评估:

1.6.2适用于安卓系统免费版和正式版(2.99$)

1.40适用于iPhone,iPad和iPod touch(ios9.0以上)免费版和正式版(2.99$)

主要特点

航海气象的气象信息和其他航海信息的编制均来源于美国国家海洋和大气观测局(NOAA)以及罗格斯沿海海洋观测实验室。你可以手动选择你想要了解信息的区域或者是允许该APP通过GPS定位的区域亦或是你的设备的服务位置。

以下是主要涵盖的数据类型

天气预报:是你所选择的区域的海上气象,该预报由NOAA预报提供,你可以通过手机或者网站从NOAA获得,其中包括了对当天以及接下来三天的风和浪的预测。

现场气象站:你所选择的NOAA浮标气象站数据大致包括(取决于浮标的类型)当时的气温,气压,风速风向和风强,露点以及浪高。

潮汐:在你所在区域选择一个或多个潮汐观测站,观测到这一天以及接下来一周的一组高潮和低潮,随着时间变化水位的高度。

潮流:在所选择的连接位置,观测到一组最大限度涨落潮和潮水以及平潮随时间一天中速度的变化。注意:这一数据仅在付费正式版可用。

日月升落:在你的位置获得一天的黎明,日升以及日落时间,同样还有月相。

海面温度:通过看一个彩色编码图了解你所选择的海域温度。

雷达影像:在你选择的地理区域通过移动的雷达影像观测近期的潮水降落。

功能

第一次使用时,那些你想要获得的图层数据(所有列表)以及在地图上想要了解的数据(通过雷达,潮汐和潮流图标站,等)的按钮都可用。你所选择的位置或者通过GPS定位信息都可以添加在收藏夹备日后使用。然后使用每种类型的数据,有很适当的图标和地图范围还有自己选择的已保存的收藏夹,并且屏幕会自己呈现出当前的数据。一般来说这些动作都很流畅且迅速。

不足

我认为最大的不足是该APP不能保存数据在线获得的数据以至于所有有用信息都只能通过在线获得。这对于只能连接WiFi的设备确实是个问题另外如果你想跑得更远一些对于手机来说也会存在缺陷,因为信号会丢失。也没有很明显的理由解释为什么会这样。尤其是当一些其他的APP都在做一些类似于潮汐信息储存以备离线使用,航海气象会和其他有把握的APP共享这些不足,就像MarineCast…还有其他APP像AyeTides可以离线保存数据,Bluefin APP开发者将会做的更好在以后的版本把这个功能加进去。另一个局限是它在潮汐和潮流的表现上用的是一个简单的表格,但这些变化都是呈正弦变化的而不是直线,有些APP则用一个图像公式来表现潮汐潮流的变化(像AyeTides在苹果设备上或潮汐潮流在安卓设备上)会更胜一筹。

最后,当去点击地图上图标获得潮汐和潮流的位置还有气象浮标特别有效,其他功能就不是很有效。如果你轻击靠近海岸的粉色区域,你会得到这一区域的预报。想要了解同一区域的水温,你还是得重复轻击按钮外的区域直到你看到一个在海上的红色区域轻击它就会获得温度。

探讨

    总之,这是一个很好的软件就航海气象预测而言,并且还是个更好的途径可以用它在出航之前了解更多关于航海气象和潮流位置。但是如果在船上一旦出现任何一点差错断了连接,被影响到,就得从其他APP获得援助确认潮流及潮汐,或许高频可以作为调整预报。另外,你可能会想要一些比NOAA所提供的还要多,还要详细的风的预报或许可以用一些其他的APP像WindNOAA或者PredictWind。PocketGrib是另一个可以显示你所在区域的风以及天气预测的很有用的APP。此APP安卓版本免费但功能有限,苹果版本会花费很多远远超出你需要信息所支付的费用。

英文原文:

TheMarine Weather app (free, with advertisements) and Marine Weather Pro app (noads, plus currents), from Bluefin Engineering, bring together in one convenientapp several types of boating weather information. While it doesn't doeverything you may want, it's a good start and makes it easy to stay in touchwith what's happening on the water, and it replaces the need to have certainother apps or bookmarked web pages on you smart device.
Even ifyou don't have connectivity while on the water, it's good to check relevantweather data before setting sail. Warning: Marine Weather does not save mostdata it downloads, so you must maintain connectivity to do updates while on thewater.

Versionreviewed: 1.6.2 for Android - free and Pro ($2.99) versions
Version also available: 1.40 for iPhone, iPad, and iPod Touch (iOS 3.0 up) -free and Pro ($2.99)

Key Features

MarineWeather compiles weather and other marine information from NOAA and RutgersCoastal Ocean Observation Lab. You can manually select the area for which youwant information or allow the app to determine your location by GPS or yourdevice's location services.

Followingare the key types of data included:

·        Weather forecast. For yourselected marine weather zone, the forecast presented is the NOAA forecast youcan get from NOAA by phone or at its website, including the wind and waves forecast for the day andthe next three days.

·        Live weather station. For yourselected NOAA weather buoy, the data may include (depends on the buoy type) thepresent air temperature, pressure, wind speed and direction and gusts, dewpoint, and wave height.

·        Tides. Selectone or more tide stations in your area and see a table of high and low tides,with times and water heights, for today and the coming week.

·        Currents. For theselected current station, see a table of maximum tidal and river currents andslack water along with speed and times for the day. Note that this one data setis available only in the paid Pro version.

·        Sun and moon set and rise. For your location, get the day's times of twilight, rise, and set,along with moon phase.

·        Sea surface temperature. For your selected ocean area, see a color-coded map of watertemperature.

·        Radar image. For yourselected geographic area, see a moving radar image of recent and currentprecipitation.

Functionality

When youfirst use the app, you enable the layers of data you want to access (the listabove) and the buttons you want to see on the map (for radar, tide and currentstation icons, etc.). You select your location or allow it to determinelocation from your GPS - and add these into favorites for later quick access.

Then, tosee each type of data, one at a time, either tap the appropriate icon or mapregion or select the data from your saved favorites, and the screen changes topresent that data. Generally these actions are smooth and fast.

The Downside

My biggest complaint is that the app does not save data once ithas accessed it online, such that all information is available only when youhave connectivity. This is a definite problem for WiFi-only devices and a shortcomingfor cellular connections that may be lost when farther out on the water. Thereis no obvious reason why this should be so - particularly since some other appsdo store information such as tides for offline use. Marine Weather shares thisfailure with certain other apps like MarineCast, while other apps like AyeTides dopreserve the data when offline. The Bluefin app developer would do well toinclude this functionality in future versions.

Anotherlimitation is the use of a simple table for tides and currents. Since thesechange in a sine wave rather than linearly, apps that show changing tides orcurrents in a graphic format (like AyeTides on Apple or Tides and Currents onAndroid) are superior.

Finally,while the use of map icons to access tide and current stations and live weatherbuoys is effective, other functions are less efficient. If you tap a pink areaof ocean near shore, for example, you get the regional forecast. To see thewater temperature for the same area, however, you have to repeatedly tap thezoom out button until you see a red area of ocean to tap for temperature.

Conclusions

All in all, this is a very good app for what it does - and oneof the best ways to learn much about marine weather and current conditionsbefore going out on the water. But if there's any risk at all of losingconnectivity once you're on your boat, be sure to have back up apps for thetides and currents - and a VHF radio for a changing forecast - if you may beaffected. In addition, you'll likely want a more detailed wind forecast thanthe general one NOAA provides and may want to use another app like Wind NOAA or PredictWind.

PocketGrib is another effective app for showing wind weatherforecasts in your area. There is a free Android version with limited functionality,but the Apple versions cost more than you need to pay for this information.

多谢翻译。
  针对原作者提出的不足我有以下想法,不一定正确哈
   其实我倒觉得不保存离线天气数据是对的,因为如果近岸,有信号,数据实时更新。有一定参考作用。远洋,必有各种专业设备。这时如果这个app不能提供实时数据也就可以不用了,毕竟海上天气瞬息万变。如果提供过期数据不符。反倒影响帆船的航线制定。
