To find out, it is useful to know where hurricanes have gone in the past.
Although striking, a growing incompleteness exists in the data the further one looks back in time.
The above map graphically indicates that hurricanes — sometimes called cyclones or typhoons depending on where they form — usually occur over water, which makes sense since evaporating warm water gives them energy .
Although incompleteness fogs long term trends and the prevalence of hurricanes remains a topic of research, evidence is accumulating that hurricanes are, on the average, more common and more powerful in the North Atlantic Ocean over the past 20 years.
