Overview
The weather exploration module enables the users to do a comprehensive dive into the weather forecasts data sets available. The data visualised in the weather exploration tab is typically received from the weather provider. The data sets that the end-user will be able to view is dependent on the weather provider, but typically will include:
Wave
Current
Wind
Location Data
Issue Data
Weather confidence factor
"In some instances, the weather page may give the user the ability to find an appropriate start date before entering a start date into your plan"
The weather data is accessed by clicking the "Weather" tab in the top menu. Details of weather data is explored by navigating the sub pages available in the left-hand side menu.
See video for tips and tricks on using the weather pages:
Toggle, filter and download weather data
In the top bar on several of the weather subpages, the user has the ability to toggle and filter on the presented datasets.
The user can also download the presented weather data into a csv file by clicking on this icon:
Weather Issue Frequency
Weather issue frequency is dependent on project and weather provider. Typical weather issue frequency is every 6 hours for tabulated weather and every 6-12hours for 2D wave spectrum data. Daily issue time may vary, but usually quite consistent.
Weather issue information and other insight may be found in the "Weather Info" subpage:
Confidence Factor
Weather confidence factors are provided by some weather providers and gives an indication of forecast reliability. The confidence factor is presented as a colored bar (available in several places in the tool) and represented as high, medium and low.
Some weather providers do not provide confidence factors.
Directional conventions
The following conventions apply to the weather data:
Waves (tabulated and spectrum) : clockwise from north, waves are "coming from"
Current: Clockwise from north, current is "going towards"
Wind, clockwise from north, wind is "coming from"
Data abbreviations, description and units
The following table contains the weather parameters requested from the weather provider.
It is not given that every forecasters provides the all of the below parameters. Because of this you might experience that some forecasters have a more limited dataset than others.
