February 2014 Global Avg. Temperature Above Normal


Did February 2014 seem much colder than normal to you?  

It sure did if you lived in the Midwest out into the Great Plains of Canada and the U.S.  At least we weren't alone, check out the "big blue blob" over central Asia!

Overall the Global average land and water temperature for February 2014 was warmer than normal (ranked 21st warmest out of 135 years of data (1880-2014) despite the much colder than normal conditions in parts of North America and Central Asia.

The February 2014 Global Highlights from NCDC are listed below the map.









Global temperature highlights: February
  • The combined average temperature over global land and ocean surfaces for February 2014 tied with 2001 as the 21st highest for February at 54.64°F (12.51°C), or 0.74°F (0.41°C), above the 20th century average of 53.9°F (12.1°C). The margin of error associated with this temperature is +/- 0.22°F (0.12°C).
  • The February global land temperature tied with 1943 as the 44th highest for February on record and the coolest since February 1994, at 0.56°F (0.31°C) above the 20th century average of 37.8°F (3.2°C). The margin of error is +/- 0.58°F (0.32°C).
  • The Northern Hemisphere land areas between 30°N and 60°N were 0.52°F (0.29°C) below average, tying with 1957 as the 60th coolest (76th warmest) for February on record and the coolest departures from average for land regions in the world during the month. The last February that was colder in this region occurred just two years ago in 2012. That month was 0.74°F (0.41°C) below average, ranking as 50th coolest (86th warmest) for February and was primarily due to cooler-than-average temperatures over most of Eurasia and northern Africa.
  • Some national temperature highlights include:
    • In Scandinavia, many areas of Finland observed February temperatures 11°-14° F (6°-8°C) above average, with some regions in the north more than 16°F (9°C) above average. For central and northern Finland, it was the second warmest February in the 115-year period of record, behind only 1990. The February temperature for Norway was 11.0°F (6.0°C) higher than the 1981-2010 average, the second warmest February on record, also behind 1990.
    • The nationally-averaged temperature for Germany was 6.1°F (3.4°C) above the 1981-2010 average, marking the sixth warmest February since records began in 1881.
    • In Canada, many regions in Ontario observed February temperatures among their 10 coldest on record and coldest in more than 30 years, with departures more than -9°F (-5°C) at some few stations.
  • For the ocean, the February global sea surface temperature was 0.81°F (0.45°C) above the 20th century average of 60.6°F (15.9°C), the seventh highest for February on record and warmest February since 2010, when El Niño conditions were present. The margin of error is +/- 0.07°F (0.04°C). The Northern Hemisphere oceans outside the tropics (20°N-90°N) were record warm on average for February.
  • Neither El Niño nor La Niña conditions were present across the central and eastern equatorial Pacific Ocean during February 2014. According to NOAA's Climate Prediction Center, there is about a 50 percent chance that El Niño conditions will develop during Northern Hemisphere summer or fall 2014.

Global Meteorological Winter (Dec. 1-Feb.28) WARMER than normal


Meteorological Winter (December 1 - February 28)
Global data set:  1880-2014, 135 years of data.

Land and water combined:  8th warmest on record
Land only, 10th warmest on record

The region with the most most below normal temperatures was the Midwest into Canada including Nebraska.  See the highlights below the map.




Global temperature highlights: December-February
  • The combined average temperature over global land and ocean surfaces for December-February was the eighth highest on record for this period, at 1.03°F (0.57°C) above the 20th century average of 53.8°F (12.1°C). The margin of error associated with this temperature is +/- 0.18°F (0.10°C).
  • The global land temperature was the 10th highest for December-February on record and highest for the period since 2009, at 1.57°F (0.87°C) above the 20th century average of 46.4°F (8.1°C). The margin of error is +/- 0.40°F (0.22°C).
  • The Southern Hemisphere middle latitude land areas were record warm for austral summer. The Northern Hemisphere land areas ranked as 11th warmest, with some sharp north-south patterns in the polar jet stream that contributed to below-average temperatures in some regions and above-average temperatures in others.
    • Summer 2013/14 was warmer than average for Australia, with a nationally-averaged temperature that was 0.81°F (0.45°C) above the 1961-1990 average. This marks the 15th warmest summer for the country since records began in 1910 and is cooler compared with last year's record-setting summer that was 2.59°F (1.44°C) above average. This summer, New South Wales, Victoria, and South Australia all observed summer temperatures among their eight warmest on record, while the Northern Territory had its 28th coldest (77th warmest) average summer temperature on record.
    • Austria observed its second warmest winter in the country's 247-year period of record, behind only the winter of 2006/07, at 4.9°F (2.7°C) above the 1981-2010 average. Switzerland had its third warmest winter since national records began in 1864, while winter 2013/14 in the Netherlands tied with 1990 for its second warmest since national records began in 1901.
    • In northern Europe, Denmark reported its fifth warmest winter for 2013/14 since records began in 1874, at 6.7°F (3.7°C) above average.
    • The United States, conversely, had its 34th coldest winter in its 119-year period of record, at 1.0°F (0.6°C) below average, the coldest winter since 2009/10.
  • For the ocean, the December-February global sea surface temperature was 0.83°F (0.46°C), above the 20th century average of 60.7°F (16.0°C), tying with 2005 as the sixth highest for December-February on record. The margin of error is +/- 0.07°F (0.04°C). Similar to February, the average Northern Hemisphere ocean surface temperature outside the tropics (20°N-90°N) was also record warm for the winter season.
