The terms "hurricane" and "typhoon" are regionally specific names for a strong "tropical cyclone".
"hurricane" (the North Atlantic Ocean, the Northeast Pacific Ocean east of the dateline, or the South Pacific Ocean east of 160E)
"typhoon" (the Northwest Pacific Ocean west of the dateline)
"severe tropical cyclone" (the Southwest Pacific Ocean west of 160E or Southeast Indian Ocean east of 90E)
"severe cyclonic storm" (the North Indian Ocean)
"tropical cyclone" (the Southwest Indian Ocean)
Are tornadoes unique to the United States?
No, tornadoes occur in many countries around the world, although three out of four twisters do touch down in the U.S. of A. They tend to occur at mid-latitudes in regions experiencing strong surface fronts and jet streams aloft. Tornadoes are rare in the tropics. Australia may be the closest to the U.S. in term of tornado potential, but the sparse population makes a climatology difficult. Other countries experiencing a significant number of twisters include New Zealand, South Africa, Argentina, and in the northern hemisphere, much of middle Europe from Italy north into England and Russia. Jolly olde England actually can get some jolly severe weather. While nowhere near as frequent as in the US, at least 50 tornadoes were reported in an 82 year period ending in 1949. October is the peak month for British twisters. Japan, eastern China, northern India, Pakistan and Bangladesh. Twisters have even spun up over Bermuda and the Fiji Islands are also at risk.
The United States averages about 1,200 tornadoes per year. The Netherlands has the highest average number of recorded tornadoes per area of any country (more than 20, or 0.0013 per sq mi (0.00048 per km²), annually), followed by the UK (around 33, or 0.00035 per sq mi (0.00013 per km²), per year), but most are small and cause minor damage. In absolute number of events, ignoring area, the UK experiences more tornadoes than any other European country, excluding waterspouts.
