![]() They will greatly simplify the work of planning specific ocean passages by showing at a glance a visual summary of wind conditions along the entire length of a chosen route. Windgrams are a summary of wind strength and direction derived from the individual windroses along a specific ocean route. The new edition has been reformatted to incorporate a new feature: monthly windgrams for the most sailed ocean routes. The comments and tips on tactics, as well as weather overviews for each ocean, were contributed by meteorologists and routers specialising in those ocean areas. Sidebars with tactical suggestions have been added to the months when most passages are undertaken. Sixty detailed charts of the most commonly sailed ocean routes make it easier to plan a route that takes best advantage of the prevailing weather conditions at that time of year. On each graph are the extent of the intertropical convergence zone, the most common trajectories of tropical storms and cyclones, and the average location of the anticyclones for each hemisphere and for all months of the year.Įighty monthly pilot charts of all oceans for the world show wind speed and direction, current speed and direction, approximate extent of the Intertropical Convergence Zone, the most common tracks of tropical storms, and the mean location of high pressure cells for each hemisphere. In addition, unlike the old pilot charts, this atlas shows the dominant direction of winds and currents for every month in all the oceans of the world, as well as along the most frequent transoceanic routes. realized ' from measurements made by satellite satellites during the last twenty years. This new atlas takes these changes into account as the cards have been removed. The pilot charts were ó realized ' from observations made a long time ago, and although they have been regularly put in place day, climate changes in recent years have rendered some information obsolete. Jimmy Cornell, experienced sailor and bestselling author, has teamed up with his son Ivan to produce a fully updated and revised second edition of Cornells’ Ocean Atlas aimed at navigators planning an offshore voyage.
