Your Classifications Are Making A Difference

Cyclone Center was the 14th project hosted by Zooniverse when it was launched in September of 2012 and only the second that was based on weather or climate data.  As we come up on our 4th birthday, we’d like share what we’ve learned so far and how your classifications over the next few months will lead to even more exciting findings.


Typhoon Nabi (2005) was a powerful storm that our classifiers successfully completed analyzing.

The reason for Cyclone Center is simple.  Tropical cyclones generally develop over remote areas of the ocean, where there are few if any direct observations of them.  It is vitally important that we know how strong these storms are for societal (e.g. warnings, evacuations, protecting life and property) as well as scientific (e.g. are storms getting stronger with climate change?) reasons.  Since storms are typically not directly measured, scientists use images of them to estimate the wind speed.  Unfortunately, although the algorithm used around the world is basically the same, it is subjective and significant disagreement has crept into the historical record.  Cyclone Center uses a special set of satellite images and classifications from you to determine a more consistent, and thus better, estimate of tropical cyclone winds.

Over the last four years, we have learned much and have had a number of notable accomplishments with your help: Read More…

The calm before the storm

It has been a quiet summer here in Asheville and on We tend to have fewer classifications in the summer, likely due to all those vacations that you’re taking.

As you come back from break, though, don’t forget to classify some storm images. We recently had a paper accepted for publication in a scientific journal (more on that in later posts) and we’re planning some big things for our fourth birthday. So check out the recent stats and go make some classifications!
