The existence of subtropical deserts, such as the Sahara, has often been attributed to the
annual‐mean, zonal‐mean Hadley circulation which shows strong descent in the subtropics�…

It is suggested that the high albedo of a desert contributes to a net radiative heat loss relative
to its surroundings and that the resultant horizontal temperature gradients induce a�…

The physiography of North Africa is not greatly changed from that of the Messinian. With the
drawdown of the Mediterranean in the late Messinian the then existing river systems were�…

An asynchronously coupled global atmosphere-biome model is used to assess the
dynamics of deserts and drought in the Sahel, Saudi-Arabia and the Indian subcontinent�…

Since Charney proposed his theory on the dynamics of deserts and droughts in the Sahel
[Charney, 1975], there has been significant scientific interest in the interaction between�…

An atmospheric general‐circulation model with realistic land‐surface properties is used to
investigate the climatic effect of doubling the extent of the earth's deserts. Control and�…

This study investigates three types of atmospheric forcing across the summertime subtropics
that are shown to contribute in various ways to the occurrence of dry and wet climates in the�…

Paleoclimatic records adjacent to India and Africa show major variability that is related to
large fluctuations in the wind and precipitation fields associated with monsoonal circulations�…

A high-resolution sedimentary record from Lake Masoko (Tanzania), based on pollen
assemblages and magnetic susceptibility, shows that the most prominent environmental�…

The PEP III Arid to Subarid Belt includes the largest hot desert in the world, the Sahara-
Arabian desert and the Sahel zone. The region of interest extends south of the Atlas�…
