Instead, letâs express these unique differences as a vector: 1  The size of the cross product is the numeric âamount of differenceâ (with sin(theta) as the percentage) 2  The direction of the cross product is based on both inputs: itâs the direction orthogonal to both (i.e., favoring neither)
Main Content. Hurricane Katrina was a long-lived hurricane that made landfall three times along the United States coast and reached Category 5 at its peak intensity. The storm initially developed as a tropical depression in the southeastern Bahamas on August 23, 2005. Two days later, it strengthened into a Category 1 hurricane a few hours before making its first landfall between Hallandale Beach and North Miami Beach, Florida.
