| Zusammenfassung |
| This study examined surface air temperature trends over global land from
1901–2009. It is found that the warming trend was particularly enhanced, in
the boreal cold season (November to March) over semi-arid regions (with
precipitation of 200–600 mm yr−1) showing a temperature increase of 1.53 °C
as compared to the global annual mean temperature increase of 1.13 °C
over land. In mid-latitude semi-arid areas of Europe, Asia, and North
America, temperatures in the cold season increased by 1.41, 2.42,
and 1.5 °C, respectively. The semi-arid regions contribute 44.46% to global
annual-mean land-surface temperature trend. The mid-latitude semi-arid
regions in the Northern Hemisphere contribute by 27.0% of the total, with
the mid-latitude semi-arid areas in Europe, Asia, and North America
accounting for 6.29%, 13.81%, and 6.85%, respectively. Such
enhanced semi-arid warming (ESAW) imply drier and warmer trend of these
regions. |
