The name Hanna or Hannah has been used for twelve tropical cyclones worldwide: five in the Atlantic Ocean, seven in the Western Pacific Ocean (five regionally in the Philippines by PAGASA) and one in the Australian Region. The latter spelling has also been used for one extratropical European windstorm. Additionally, the similar name Hana was used once in the Central Pacific.
