PropertiesEdit. 1  The scalar triple product is invariant under a circular shift of its three operands (a, b, c): a â ( b Ã c ) = b â ( c Ã a ) = c â ( a Ã b ) {\displaystyle \mathbf {a} \cdot (\mathbf {b} \times \mathbf {c} )=\mathbf {b} \cdot (\mathbf {c} \times \mathbf {a} )=\mathbf {c} \cdot (\mathbf {a} \times \mathbf {b} )}.
2015 Pacific hurricane season. The 2015 Pacific hurricane season is the second-most active Pacific hurricane season on record with 26 named storms, only behind the 1992 season. A record-tying 16 of the storms became hurricanes, and a record 11 storms became major hurricanes throughout the season.
In the Northwest Pacific, the same powerful storms are called typhoons. In the Southeastern Indian and Southwest Pacific Oceans they're called severe tropical cyclones. In the North Indian Ocean, they're called severe cyclonic storms, while in the Southwest Indian Ocean, they simply keep the name tropical cyclone. Hurricanes that make Category 3 status on the Saffir-Simpson Hurricane Wind Scale (winds of at least 96 knots or 111 mph) are labeled intense hurricanes.
