Index to the Resource section.

The resources are a collection of data, computers, graphs, and other tools that help with the analysis or application of marine weather information underway and in planning. The full list is reproduced below. Samples or screen captures from several of them are presented here in this tour. These are the tools that you will continue to use after the basic learning process is completed.

Weather Trainer Resources

1. How to read weather maps
Shows the types of fax maps available with explanations of each, plus how to use the information tactically. Includes cross references to related articles.
2. Sea state
Abbreviated list of notes on waves, definitions and statistics of wave production, plus a sea state computer predicts waves from various wind speeds.
3. Worldwide fax schedules
Full text copies of all weather fax broadcast schedules (64 of them) around the world, plus a section on how to interpret the schedules.
4. Forecasting tips
Summary of how to use clouds, wind, seas, and barometer to help with shipboard forecasting based on these observations.
5. True wind from apparent wind
Explains this conversion (and vice versa) using dedicated computer, or by calculator and equations, and by direct plotting of the vector triangle.
6. Storm avoidance computer
Calculates optimum course to steer to put maximum distance between you and approaching storm plus shows results of taking various courses other than the optimum.
7. Pressure versus elevation
Computes barometer corrections for instruments located above sea level, as they might be on land or on very large vessels.
8. Time zones and map times
Converts valid map times in GMT to watch or zone times. Also computes zone description from longitude if needed. Lists ZDs for various standard time zones.
9. Visibility and luminous range
Presents visibility codes and luminous range diagram for predicting visible range of lights in reduced visibility.
10. Dew point and relative humidity
Tables of these data and notes on their use in coding and fog prediction along with a computer for quick interpolation.
11. Tools
Important notes on using the this course most efficiently. Explains features and use of the toolpad items: Glossary, notepad, calculator, units conversion, and abbreviations windows along with notes on the various computers included in the course.
Describes NAVTEX services and schedules worldwide, with cross references to Radio Primer on radio terms and usage. This is just a direct link to part of the Source Book, RES-17.
13. Wind chill factors
Table of factors and notes on their use.
14. Cloud Atlas
Covers cloud terminology and identification along with how to choose the proper cloud codes for weather reports plus the practical meanings of common cloud forms.
15. Weather codes
Explains the international system of reporting weather observations via abbreviated codes to the National Weather Service.
16. World atlas
Presents winds, pressures, and currents for the major oceans, along with statistics on hurricane zones and frequencies, forecast regions, and areas covered by specific Sailing Directions and Pilots, plus more.
17. Sources of weather information
Summarizes all sources of weather data with explanations or direct links to related sections including broadcast schedules. Includes lists of references and related publications, both printed and electronic.
18. Radio Primer
Explains the role of radio in marine weather, background on radio waves, frequency and channel assignments, and general tips on radio usage. The Radio Primer is located in the Source Book.
19. Further reading
A direct route to the book and magazine section of the Source Book, RES-17.
20. Navigator's check list
A list of books, tools, and other aids to remind us what we need underway and not to forget it. (As a navigation school, we cannot resist putting something like this in everything we publish.)
21. Beaufort scale
Notes on the origin and evolution of this scale and specific descriptions of wind and sea for each force number. The Beaufort scale is in a graphics book (G231). It is also available from the menu bar under tools.
22. Symbols Book
A catalog of weather map symbols along with their definitions. It is in a graphics book and also available from the menu bar under resources.
23. Internet sources
An overview of the types of information (marine weather and navigation) that is available on the internet. Specific references are given, along with a reminder to check our own home page for updates.
