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.
The eleventh named storm and fifth hurricane of the 2005 Atlantic hurricane season, Katrina originated over the Bahamas on August 23 from the interaction between a tropical wave and the remnants of Tropical Depression Ten. Early the following day, the new depression intensified into Tropical Storm Katrina.
