TREND ANALYSIS: Trends at High Elevation Sites

Climatic Change, 36(3-4), July-Aug. 1997 (Kluwer Academic Publishers) is a special issue on this topic with an overview and ten specialized papers. The overview and one other paper are listed here.

Item #d98mar41

"Climatic Change at High Elevation Sites: An Overview," M. Beniston (Inst. Geog., Univ. Fribourg, Pérolles, CH-1700 Fribourg, Switz.), H.F. Diaz, R.S. Bradley, 233-251.

There are clear indications from a number of high elevation climate records that the amplitude of temperature changes this century is greater than the observed global or hemispheric change. Some evidence suggests that the warming signal in the tropics during the past few decades is amplified with height.

Item #d98mar42

"Temperature Variations During the Last Century at High Elevation Sites," H.F. Diaz (NOAA/ERL/CDC, 325 Broadway, Boulder CO 80303), R.S. Bradley, 253-279.

Reviews evidence for appreciable differences in mean temperature changes with elevation during the last several decades of instrumental records, especially in western Europe and parts of Asia. The signal appears to be more closely related to increases in daily minimum temperature than changes in the daily maximum.
