چکیده

Two integrations of a global general circulation model, differing only in the prescribed surface albedo in the Sahara, show that an increase in albedo resulting from a decrease in plant cover causes a decrease in rainfall. Thus any tendency for plant cover to decrease would be reinforced by a decrease in rainfall, and could initiate or perpetuate a drought.

Comment on "Climate-driven ecosystem succession in the Sahara: the past 6000 years".

Kröpelin et al. (Research Articles, 9 May 2008, p. 765) interpreted a sediment record from Lake Yoa in the east-central part of North Africa as support for a weak biogeophysical climate-vegetation feedback in the Sahara during the mid-Holocene. We argue that the new data do not invalidate earlier modeling results on strong land-atmosphere coupling in the Western Sahara for which the Lake Yoa re...

Quantification of Land-Atmosphere Coupling and Implications for Drought Persistence In Observations and Model Simulations of 20th Century Climate and 21st Century Climate Change

Of all recurring natural disasters, long-term drought is one of the most devastating and costly due to large spatial extent and often long duration. The mechanisms responsible for the maintenance of long-term droughts are not well understood, however many drought analyses allege the importance of land-atmosphere feedbacks and speculate that these feedbacks will amplify changes in the hydrologic...

The role of ecosystem-atmosphere interactions in simulated Amazonian precipitation decrease and forest dieback under global climate warming

A suite of simulations with the HadCM3LC coupled climate-carbon cycle model is used to examine the various forcings and feedbacks involved in the simulated precipitation decrease and forest dieback. Rising atmospheric CO2 is found to contribute 20% to the precipitation reduction through the physiological forcing of stomatal closure, with 80% of the reduction being seen when stomatal closure was...

The influence of inter-annually varying albedo on regional climate and drought

Albedo plays an important role in land–atmosphere interactions and local climate. This study presents the impact on simulating regional climate, and the evolution of a drought, when using the default climatological albedo as is usually done in regional climate modelling, or using the actual observed albedo which is rarely done. Here, timevarying satellite derived albedo data is used to update t...
