atmospheric condition - wise , this has been a rather strange and memorable winter . A North Americanpolar vortexand frigidMars - like temperatureswill do that . As this raw NASA Earth Observatory map beautifully illustrate , it has been an anomalous wintertime , indeed .
The function above prove land surface temperature anomalies in North America for January 1 to 7 , 2014 . Data was acquired by the Moderate Resolution Imaging Spectroradiometer ( MODIS ) on NASA ’s Terra satellite .
The mapping portray temperatures for this period compare to the 2001–2010 norm for the same workweek . surface area with warmer than average temperatures are shown in scarlet , near - normal temperatures are blank , and area that were cooler than the base period are shown in blue .
A second map shows temperature anomalies in Europe during the same geological period ( grey make up areas where clouds blocked the satellite from collect operable data . ):
During rough this same catamenia , Australia suffer an acute heatwave that brought book - breaking temperature , while in South America , Argentinians faced a two - hebdomad heatwave that supercharge temperatures more than 15 ° C ( 27 ° F ) above average in some areas , get widespread power and water shortages .
“ It ’s beguiling to link individual weather condition events like this to extensive discussions of mood change , and there certainly are some interesting theories out there , but the skill really is n’t mature enough at this peak to make any meaningful connections , ” tell atmospherical scientist Paul Newman in an EO handout . “ One - off events like this are neither evidence for or against clime change . ”
For certain , the cold spell in the U.S. only represented about 2 % of the Earth ’s full climate . But still — it ’s been a rather unknown and grievous winter ( in the north ) and summer ( in the south ) .
