Astronomy Picture of the Day -- Hurricane Paths on Planet Earth
NASA ^ | September 04, 2012 | (see photo credit)

Explanation: Should you be worried about hurricanes? To find out, it is useful to know where hurricanes have gone in the past. The above Earth map shows the path of every hurricane reported since 1851, 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. The map also shows that hurricanes never cross -- or even occur very near -- the Earth's equator, since the Coriolis effect goes to zero there, and hurricanes need the Coriolis force to circulate. The Coriolis force also causes hurricane paths to arc away from the equator. 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.

Not much of an APoD, but a little interesting. Of course, the Earth is 400 million light years in the future. /s

gotta admit, putting new orleans where it is, and 9 feet below sea level, looks, at least on this chart, to be kind of a bad idea, no matter how many levees you build.

Living next to a river is an even worse idea.

Dust causes hurricanes. Start irrigating the Sahara and Florida gets a break.

Dust causes hurricanes.

Actually, this article title says that, but the abstract seems to describe the opposite, that is, dust storms that go out over the Atlantic from the Sahara, tend to suppress hurricane activity.

Down here in the South, we hope for mild tropical waves to come through in summer so we can get some rain.

Florida would be a desert without them. And still is some years.
