Summary
| Description |
English: This image shows annual anomalies of maximum and minimum temperatures and diurnal temperature range (DTR) (°C) relative to the 1961 to 1990 mean, averaged for the 71 percent of global land areas where data are available for 1950 to 2004. The smooth curves show decadal variations. The image is based on work by NOAA employees (Vose et al., 2005, referred to by Trenberth et al., 2007). From the cited public-domain source (NOAA, 2010): "There has been a general, but not global, tendency toward reduced diurnal temperature range (DTR: the difference between daily high or maximum and daily low or minimum temperatures) over about 70% of the global land mass since the middle of the 20th century. However, for the period 1979-2005 the DTR shows no trend since the trend in both maximum and minimum temperatures for the same period are virtually identical; both showing a strong warming signal. A variety of factors likely contribute to this change in DTR, particularly on a regional and local basis, including changes in cloud cover, atmospheric water vapor, land use and urban effects."
