A Course on Disasters

This coming winter quarter at UC Davis, I will be teaching a course on disasters.  Because most of the books on this subject cost well over $100 US, and even over $150 US, I decided to produce an online course from sources at Wikipedia pages and various US government sources.  Since these are subject to common use licenses, reproducing subject matter from those courses is within the varous terms of use restrictions.  I will be making the lectures openly available here.  Interested students and faculty can feel free to us

The 2013 Atlantic Hurricane Season: Why so few Storms?

As some may recall, the 2013 Hurricane season was expected to see an above average number of storms.  However, this season saw the fewest number of storms and severe storms in decades.  Some possible reasons are discussed here.

Thanksgiving Week Storm on the US East Coast, 2013

The week before Thanksgiving in the United States is usually a time when many people travel to return home to family and friends.  Last week a major storm threatened to disrupt these travel plans, but fortunately did not to any great extent.  Animation of this weather event was captured by the NASA GOES East satellite as below.  Further details can be found here.

2013 was a quiet season for hurricanes in the Atlantic.  In the Pacific however, one hurricane (called typhoons there) drew lots of attention --  Typhoon Haiyan.

I’ve blogged about hurricanes several times here…

How do they measure those typhoon wind speeds, anyway?

A brief summary and graphic can be found here.

Will future typhoons be stronger and more destructive?

Storm surge simulations of Haiyan and other cyclones, together with other types of analyses suggest this.  And many climate scientists think so.  What does this mean for countries such as the Philippines, which has seen death and destruction on an unimaginable scale?  For those trying to forecast the future, simulations offer a viable means of scenario-building.
