Regional variations in temperature

Regional temperature can vary widely, with some regions colder than average even when the global temperature is warmer than average.

The data

We use data from Met Office-CRU, NOAA NCDC, NASA GISS and Met Office operational analyses used in weather forecasts.

The operational analysis uses all available data, including from satellites, giving full global coverage. The other analyses only use surface observations to maintain continuity over the complete record from the late 19th century to the present.

Temperature anomalies (temperature differences from the 1961–1990 average) from the Met Office–CRU dataset Temperature anomalies  

Met Office-CRU dataset

The Met Office-CRU graphic shows temperature anomalies (temperature differences from the 1961-1990 average) from the Met Office-CRU dataset. The diagram to the right of the map (seen when you enlarge) shows the zonal average temperature anomaly - the average temperature anomaly averaged around each 5-degree latitude band.

National Climatic Data Center (NOAA NCDC) dataset

The NOAA NCDC graphic on the left shows temperature anomalies (temperature differences from the 1961-1990 average) from the NOAA NCDC data set produced by the NOAA National Climate Data Center. The diagram to the right of the map (seen when you enlarge) shows the zonal average temperature anomaly - the average temperature anomaly averaged around each 5-degree latitude band.

The NASA GISS graphic on the left shows temperature anomalies (temperature differences from the 1961-1990 average) from GISS which is produced by the NASA Goddard Institute for Space Studies. The diagram to the right of the map (seen when you enlarge) shows the zonal average temperature anomaly - the average temperature anomaly averaged around each 5-degree latitude band.

Met Office operational analyses

Combined land air temperature and sea surface temperature anomalies for the year so far. Anomalies (differences from the climatological average) are obtained from the Met Office daily operational analysis over land and from the daily  OSTIA analysis for the ocean.
