INTRODUCTION

Nearly everyone who sails much has a clear image in mind of such weather phenomena as warm and cold fronts and highs and lows and roughly what to expect as they arch majestically across the daily weather maps in newspapers and the TV screen. It all seems easy to understand and forecasts are, at least somewhat more often than not, correct. But it’s the times that forecasts are not correct which most concern us when we’re at sea. There are so many variables which all together must be accounted for in order to arrive at an accurate weather forecast that we may as well forget about reaching that ideal in our lifetimes. One scientist pointed out years ago that a butterfly flapping its wings over a parking lot on a hot day in Dallas may be the cause of a thunderstorm in Boston three days later. It was meteorologists who led the way to the new science named, appropriately, CHAOS. But take heart! In Steve and Linda Dashew’s Mariner’s Weather Handbook, we are given an expanded, three-dimensional view of the atmosphere in which we live. They describe a swirling, boiling cauldron of rising, deciding, veering, backing, colliding and diverging air currents of uneven temperatures and moisture contents. With this expanded vision and with some of the more recently available tools—such as the Internet, high seas radio, weather fax, satellite photos, and others—the voyager can come closer than ever before in relating macro scale forecasts to his/ her own particular patch of ocean, and making decisions on whether to begin evasive actions, and which ones. Their book is well-named a handbook. Just once through will suggest a new way of looking at weather. Repeated return visits as puzzling or threatening weather is observed will confirm and amplify its value. Knowles L. Pittman, Circumnavigator and Publisher of One Design Yachtsman
