I just searched for "polar vortex" and got about 17,000,000 results.  Apparently the number doesn't display when specifying a date range; I wonder how many would have come up if I had searched a week ago!  And searching for "polar vortex" "global warming" gives 78,300,000.

Looking at those topics in relation to the recent cold weather over parts of the U.S. and Canada from an objective, scientific perspective ...

Meteorological Images of 2013

My 8th annual edition. For 2013, they just happened to work out to be an even Top 20, presented in the chronological order in which they occurred, not ranked except for my choice for the "image of the year" at the end.

Sometime in early 2014 I'm going to post my selections for the top meteorological images of all time!

So much to blog about recently (derechos, meteotsunamis, hurricane season outlooks), so little time!

Now what happened last weekend. If it looks, walks and quacks like... at least a tropical depression not far from tropical storm streng...

After the February 8-9 blizzard, I posted for that storm a special edition of my "meteorological images" series; there were other significant weather systems during February and in turn other vivid visualizations, and here is a selection of them which not only are cool to look at but chronicle the month's weather highlights.

Meteorological images of the blizzard

By: Stu Ostro, 4:32 AM GMT on February 14, 2013

The recent epic blizzard in the northeast U.S. and modern weather technology produced vivid meteorological images which I've compiled into a storm-specific version of my monthly/annual series.

While these images are captivating to look at, they also represent interesting meteorological things about the storm, one which produced very significant impacts and, tragically, loss of life even though the blizzard was well forecast. Every event is unique, has i...
