Hurricanes are tropical storm systems that form only over warn ocean water. Tornadoes are less limited. They usually form on land in temperate climates, but they can occur on water (in which case they are called waterspouts) and in tropical regions.
No. Tornadoes do not have names; hurricanes do. One term relating to tornadoes that starts with 'a' is anticyclonic. An anticyclonic tornado is one that spins in the opposite direction from what is normal. That is, it spins clockwise if it is in the northern hemisphere and counterclockwise if it is in the southern hemisphere.
No, There is no type of tornado that starts with X. Tornadoes can be divided into supercell tornadoes, landspouts, and waterspouts. Some supercell tornadoes are also multivortex.

There are no hurricanes starting with the letter Y. The letters Q, U, X, Y, and Z are not used for hurricane names.

First and foremost, the Saffir-Simpson scale is used to rate hurricanes while the Fujita scale is used to rate tornadoes. The Saffir-Simpson scale is based on direct wind measurements, with the winds for each category generally being lower than those of the "equivalent" levels on the Fujita Scale (now the Enhanced Fujita scale in the U.S.), for example, a category 5 Hurricane starts at 156 mph while an F5 tornado starts at 261 mph (201 mph for an EF5). Furthermore, the (Enhanced) Fujita scale bases ratings on damage rather than direct wind measurements, with the winds being estimates. These differences are dues to the fact that tornadoes are much smaller and shorter-lived than hurricanes, making it very difficult or even impossible to get direct wind measurements. The winds for the (E)F scale categories are higher than those on the Saffir-Simpson scale largely because tornadoes can have much faster winds: tornadoes can have winds over 300 mph, while the very strongest of hurricanes have winds of about 200 mph.
No. Tornadoes come from thunderstorms, which form in the air. The tornado itself starts forming several thousand feet above the ground.
Hurricanes often begin as disturbances off the coast of Africa.

Hurricanes do not form in Barbados, but they can strike there. Hurricanes develop from clusters of thunderstorms over warm ocean water. These clusters gain energy from the moisture that evaporates from the warm water and can organize and intensify to become hurricanes. Large-scale wind patterns then direct how these hurricanes move. Some of the resulting paths go across Barbados. Many of the hurricanes that affect Barbados and surrounding areas starts as disturbances that move off the west coast of Africa.
