The North Atlantic may feel like the epicenter of tropical cyclone activity, but it’s not, since it generates an average of only 10 named storms a year compared to 36 in the North Pacific. If you really want to escape the clutches of these monsters, the place to be is the South Atlantic. As you can see from this composite tracks map, the South Atlantic generated only one tropical cyclone in the 20 years between 1985-2005. Why the tranquility? Well, it’s less a factor of colder ocean temperatures than strong vertical wind shear, which shreds big systems before they can form. Plus the the South Atlantic typically has no intertropical convergence zone (the Doldrums, in sailor speak) to drive large scale spin and thunderstorm activity.

A BETTER WAY TO DO THIS?

We have an ambitious $350,000 online fundraising goal this month and we can't afford to come up short. But when a reader recently asked how being a nonprofit makes Mother Jones different from other news organizations, we realized we needed to lay this out better: Because "in absolutely every way" is essentially the answer.

So we tried to explain why your year-end donations are so essential, and we'd like your help refining our pitch about what make Mother Jones valuable and worth reading to you.

We'd also like your support of our journalism with a year-end donation if you can right now—all online gifts will be doubled until we hit our $350,000 goal thanks to an incredibly generous donor's matching gift pledge.
