Severe Weather on the High Seas

Many seafarers find themselves subjected to harsh elements, and when it comes to the ocean, nothing “stirs the pot” like the wind; and the winds are a response to pressure differences.
More specifically, winds move from high to low values of pressure, and the greater the differences between the pressure fields, the faster the wind moves.  A good way to visualize this process is to imagine a ball rolling down a hill: the steeper the slope of the hill, the faster the ball will roll. Oh gravity, thou are a heartless force. High pressures can ultimately be thought of as “hills”, the low pressures as the “dips”, and the ball is the “wind”. So when analyzing atmospheric pressure patterns, much like a contour elevation map would indicate the steepness or grade to a hiker, tightly spaced pressure contours indicate a steep pressure change pattern, hence higher winds. click here to read the article 08:57
