Cornell’s Ocean Atlas


Pilot charts for all oceans of the world ISBN:9780955639654

by Jimmy & Ivan Cornell

"This atlas is aimed primarily at cruising sailors planning or undertaking an ocean passage. Our main objective has been to create the kind of publication we would have greatly appreciated if it had been available when we sailed on any of the five circumnavigations of the globe which we share between us." - Jimmy and Ivan Cornell

All sailors, even experienced ones, planning to set off on a shorter or longer offshore passage are concerned about what kind of weather they might encounter. The wise navigator will prepare for the worst eventuality but do everything possible to avoid it.

The main role of the Cornell’s Ocean Atlas is to allow you to check out wind conditions for every month of the year in any ocean of the world and thus gain an immediate overall knowledge of what you can expect at any given time of year.

Much of the information contained in the pilot charts that are in use today is still based on observations from the 19th century and, although they have been updated at regular intervals, the scarcity of reliable sources, inaccuracy of the observations, or the climate changes that have occurred over the years, have rendered some of the information shown on those charts to be now inaccurate.

To present as true a picture as possible of the actual conditions which prevail in today’s oceans, the pilot charts in Cornell’s Ocean Atlas are based on the most recent weather data gathered by a network of meteorological satellites over the last 20 years. South Pacific Ocean / March

60 monthly up-to-date pilot charts of all oceans of the world show
•wind speed and direction
•current rates and direction
•approximate extent of the Intertropical Convergence Zone, commonly known as the doldrums
•the most common tracks of tropical storms
Lesser Antilles and California
to Galapagos / February•and the mean location of high pressure cells for each hemisphere

This is the kind of information you need even before you start actually planning a specific voyage, as it will allow you to decide straight away whether your plan is feasible. Once you've decided that it is, you can proceed to the next stage, and that’s to plan a voyage along a route that has the best chance of favourable sailing conditions.

And this is where the rest of Cornell’s Ocean Atlas comes to your help
•Side by side with the monthly charts are 69 detailed charts of the most commonly sailed transoceanic routes. Even sailors with limited offshore experience will find it easy to plan a route that takes best advantage of the prevailing weather conditions at the chosen time of year.
•Sidebars with tactical suggestions have been added to the months when most passages are undertaken.
•The comments and tips on tactics, as well as weather overviews for each ocean, were contributed by meteorologists and routers specializing in those oceanic areas.
•Furthermore, the Atlas also contains a comprehensive description of weather conditions in every ocean.

129 up-to-date pilot charts. 120 pages. Pub 2012.
