In the above Earth map you can see every known hurricane and tropical storm since 1851. If you worry about hurricanes and you like to know where have gone in the past, have a closer look at the chart after the jump. Image credit: John Nelson, IDV Solutions
The above map indicates that hurricanes (or cyclones, or typhoons), usually occur over water, which makes sense since evaporating warm water gives them energy.
The map also shows that they never occur very near the Earth’s equator, since the Coriolis effect goes to zero there (hurricanes need the Coriolis force to circulate) and also causes hurricane paths to arc away from the equator.
