properly correspond to this product, all observations were categorized 

 according to speed and direction, forming a probability matrix. The matrix, 

 when contoured, exhibited various combinations of wind speed and direction 

 that correspond to each probability of occurrence. The matrix was adjusted to 

 account for the length of record from the measurement site. For wave and 

 water level estimates, the combination of wind speed and direction was chosen 

 that would potentially generate the highest waves and winds. For Bay Ridge, 

 the following design wind conditions were determined:

 were uniformly applied to a simple numerical finite difference storm surge
