- This dataset shows some of the major November weather and climate highlights from the National Climatic Data Center’s (NCDC) monthly global climate analysis, and serves as an overview of what can be discussed in the datasets that follow. Highlights are noted below with more information.
- Western U.S.: Much of the western U.S. had below-average precipitation during the January-November time period.
- Alaska: Experienced its third wettest November on record (since 1918).
- Typhoon Haiyan: Nov. 3-11; Max. Winds: 315 km/hr; Landfall in the Philippines; over 6,000 fatalities.
- Russia: Warmest November on record (since 1891).
- Spain: Coolest November since 1985.

Sea Surface Temperature Anomalies Dataset
Dataset: 20131220 EarthNow: November 2013 SST Anomaly
Dataset: 20131220 EarthNow: AUDIO November 2013 SST Anomaly
- The real-time sea surface temperature anomaly dataset is a great way to visualize the El Niño – Southern Oscillation (ENSO) cycle in the eastern tropical Pacific ocean. For November 2013, these waters hovered near average, indicating an ENSO Neutral period. The Climate Prediction Center anticipates a continued neutral period into the northern hemisphere summer.
- Global water temperatures tied with 2009 as the third warmest November on record.
Remember that the blues indicate cooler than average temperatures and reds indicate warmer than average temperatures (white: average).

Snow and Ice Cover Dataset
Dataset: 20131220 EarthNow: November 2013 Snow and Ice Cover
Dataset: 20131220 EarthNow: AUDIO November 2013 Snow and Ice Cover
- Aside from helping to illustrate seasonal changes, the real-time Snow and Ice Cover dataset is a great way to convey sea ice change through time, including discussing how the current sea ice extent compares to other noteworthy years.
- The Arctic sea ice extent for November 2013 was the sixth lowest on since satellite records began in 1979.
- In Antarctica, the sea ice extent was the largest on record.
Where do I find the datasets?
