Way Weird Weather

Author: Hugh Bollinger/Friday, August 8, 2014/Categories: natural history, environment, climate change

July has produced some really weird weather across the northern hemisphere. Temperatures have been reversed from what is normally typical.

According to NASA: "In places where it should be seasonably hot—the eastern/southern United States and western Europe—it has just been warm. In places where weather is usually mild in the summer—northern Europe and the Pacific coast of North America—it has been ridiculously hot."

Two new 'big-data' maps illustrate the story visually:

Researchers for the Aqua Project reported:

"Records for high temperatures (mid-90s°F) were approached or broken in Latvia, Poland, Belarus, Estonia, Lithuania, and Sweden in late July and early August. Searing temperatures also dried out forests and fueled wildfires in Siberia; in the U.S. states of Oregon, Washington, and California; in the Canadian provinces of British Columbia, Alberta, and Northwest Territories; and even in Sweden. At the same time, cool air moved from high latitudes into much of the U.S., setting record-low daytime and nighttime temperatures as far south as Florida and Georgia. Temperatures dropped to the winter-like levels in the mountains of Tennessee."

Anomalies in the jet stream have allowed  heat domes  to develop and deflect weather fronts that would normally bring wind, precipitation, and temperature changes to entire regions. Investigations continue but atmospheric changes is suspected of playing a big part.

We could be in for much more 'way weird weather' to come.
