2013-14 - An Interesting Winter From A to Z

By: Tom Niziol, 6:46 PM GMT on May 15, 2014

The Weather Channel named 26 winter storms this past season. The naming process evaluates the winter impacts across a minimum population in the U.S. based on Winter Weather Warnings and Advisories issued by the National Weather Service. Each of these storms produced a wide variety of winter impacts across different parts of the nation. The rest of this article will detail those storms on a month to month basis beginning in October and ending in May.

Record Ice Cover On The Great Lakes For This Time of The Year

By: Tom Niziol, 5:09 PM GMT on April 25, 2014



One of the most talked about stories of this past winter and spring has been the record ice cover for this time of the year on the Great Lakes. It has been an exceptional year to say the least. This year the lakes attained their highest percentage of ice cover on March 6, 2014 when they reached 92.2% coverage. The only year since modern satellite-derived records began back in 1973 that achieved a higher percentage of ice cover was in 1979 when it reac...

Astronomical VS. Meteorological Winter

Now that we are getting toward the end of winter, I through it might be interesting to explain the differences in how winter is defined from an astronomical and meteorological standpoint. I am pretty certain everyone is familair with the astronomical-based seasons. They are defined by the rotation of the earth around the sun and the tilt of the earth's axis. In Figure 1, I have outlined the tilt of the earth's axis in relation to the sun throughout the year. As...

NORTHEAST SNOW STORM - THE PIVOT POINT

By: Tom Niziol, 5:43 PM GMT on February 10, 2013

This is a quick look at the Upton New York radar loop (courtesy College of DuPage NEXLAB) from 1800 UTC 2/8/13 through 0800 UTC 2/9/13 at approximately 15 minute intervals. The point I want to make with this animation is to show how the band from NEMO sets up across Long Island and literally pummels them for several hours. Note how the band pivots right across the island as the Low moves from south to north several miles to the east of the island during the night....

Snow Pack Across The Sierra

By: Tom Niziol, 12:25 PM GMT on February 05, 2013

As many people who follow my blogs know, I absolutely love to view the high resolution imagery available from our nation's polar orbiter satellites. These satellites orbit from pole to pole at a low height, around 450 miles, compared to geo-stationary satellites which orbit around 23,000 miles above the earth. Although polar orbiters only provide a couple images a day at any one point on earth, they provide very high resolution photos. I got hooked looking at the...
