Remember the Polar Vortex? After a scorching hot summer in places like California, Arizona, and even Oregon, it’s hard to believe that half the country was freezing cold just a few months ago. But according to Climate.gov it’s been that kind of year—both unusually hot and unusually cold.
The latest U.S. weather data shows that 2014′s temperature extremes—that is, temperatures in the top or bottom 10% of the historical range of values recorded for a given location—have been well, more extreme, than usual.
The graph below illustrates the historical range in extreme temperatures dating back to 1910. The bars represent the percent of the country experiencing extremely hot or cold average maximum temperatures.
Climate.gov explains how 2014 has been such an outlier:
In most years in the record, extremes are significantly lopsided: a given year’s bar is mostly red or mostly blue, sometimes capped with a small segment of the opposite color. In other words, either some part of the country is experiencing warm extremes or cold extremes, but not both. Only a handful of years have a pattern similar to 2014—in which more than 10 percent of the country was experiencing extreme warmth while a similarly large or larger area experienced extreme coolness.
So it’s been a weird year for weather. And according to scientists studying the jet stream, there’s more ahead. That means that depending on where you live, your A/C or heating system is bound to see some action through the end of the year.
And with such unpredictable weather, out there staying indoors doesn’t sound too bad. (Good thing it’s football season again!)
