The first edition, published in 2012, was based on satellite observations undertaken in the previous 20 years (1991-2011). The second edition is fully revised and updated by incorporating data gathered during the last five years (2011-2016). So the data now spans 25 years and also reflects any changes that have occurred during this latest period.
Besides that, the new edition will also be reformatted to incorporate a new feature: monthly windgrams for the most sailed ocean routes. Windgrams are a summary of wind direction amd strength derived from the individual windroses along a specific ocean route.
Cornell’s Ocean Atlas is:
- The first significant innovation in pilot charts — an essential tool for passage planning — since pilot charts were developed by Lieutenant Maury of the US Navy in the mid-1800s.
- The first and only pilot charts to be based on extensive near real-time geospatial and remote buoy sensing data from 1987 to the present measuring true surface wind and current – gathered from a network of OSCAR and other meteorological satellites, using NOAA and Earth and Space Research (ESR) data programs
- An integral part of Jimmy Cornell’s World Cruising Series – works hand-in-hand with World Voyage Planner, World Cruising Routes and World Cruising Destinations
60 monthly up-to-date pilot charts of all oceans of the world show:
- current rates and direction
- wind speed and direction
- approximate extent of the Intertropical Convergence Zone, commonly known as thedoldrums
- the most common tracks of tropical storms
- and the mean location of high pressure cells for each hemisphere
Canary Islands and New York to the Lesser Antilles (Caribbean)69 detailed charts of the most common transoceanic routes including:
- Lesser Antilles (Caribbean) to New York and Azores
- Lesser Antilles (Caribbean) and California to Galapagos
- Pacific Northwest and California to Lesser Antilles (Caribbean)
- Pacific Northwest to Galapagos and Marquesas
- California to Hawaii and Alaska
- Panama to Marquesas and Hawaii
- Australia and New Zealand to Tahiti and Fiji
- Tonga to New Zealand and the Torres Strait
- Seychelles to South Africa
- South Africa to North East Brazil
- Plus expanded detail for the Caribbean Sea, Mediterranean, Baltic Sea
Comprehensive description of weather conditions in every ocean.
Sidebars with tactical suggestions have been added to the months when most passages are undertaken.
Comments and tips on tactics, as well as weather overviews for each ocean, were contributed by meteorologists and routers specializing in those oceanic areas, such as Lee Chesneau, Peter Gibbs (BBC), Herb Hilgenberg, Bob McDavitt (New Zealand Met Office) and John Neal.
From Jimmy Cornell:
“The main objective of Cornell’s Ocean Atlas is to make it possible to take advantage of prevailing winds and seek out whenever possible favourable conditions. Essentially, to try to always be in the right place at the right time, or, better still: Not to be in the wrong place at the wrong time!”
