| Zusammenfassung |
| According to trend computations at three stations each in Sahara desert (Libya), characterized
by a “hot” desert type (“BWh”, according to the Koeppen climate classification), and in
Central Asia (Xinjiang, China) identified as a “cold” desert type (“BWk”, after Koeppen),
increasing annual temperatures were detected over the period 1955-2005 corresponding with
global temperature warming.
From 1955-1978, negative (decreasing) temperature trends were, however, observed at all
three hot desert stations and at two of the three cold desert stations. From 1979-2005,
strikingly positive temperature trends were seen at all six stations.
In seasonal respects, winter (December to February) and summer (June to August) show
different temperature trends over the period 1955-2005: the hot desert experienced an
increasing temperature trend at a greater extent in summer than in winter; vice-versa, in the
cold desert positive trends were computed for winter and negative for summer. It can also be
observed that mostly hot desert warming occurred in summer, opposite to cold desert
warming in winter. |
