Very sparse data have previously limited observational studies of meteorological processes in the Sahara. We present an observed case of convectively driven water vapor transport crossing the Sahara over 2.5 days in June 2012, from the Sahel in the south to the Atlas in the north. A daily cycle is observed, with deep convection in the evening generating moist cold pools that fed the next day's ...

Tropical cyclones (TCs) can have devastating socioeconomic impacts. Understanding the nature and causes of their variability is of paramount importance for society. However, historical records of TCs are too short to fully characterize such changes and paleo-sediment archives of Holocene TC activity are temporally and geographically sparse. Thus, it is of interest to apply physical modeling to ...

Although the Sahara is a major geographical feature of the African continent, its role in the diversification of animal species is not well understood. We present here a molecular phylogeny for members of the endemic African mammalian order Macroscelidea (elephant shrews) with molecular-clock calculations; this molecular phylogeny provides convincing evidence that the genus Elephantulus is diph...

Abstract. Previous studies based on multiple paleoclimate archives suggested a prominent intensification of the South Asian Monsoon (SAM) during mid-Holocene (MH, ∼6000 years before present). The main forcing that contributed to this is related changes in Earth's orbital parameters. Nonetheless, other key factors likely played important roles, including remote vegetation cover and airborne dust...

he virulence of the 1998 turbulence in the mature financial markets took market participants and authorities by surprise , and some have acknowledged that they do not fully understand the rapidly changing structure and dynamics of global financial markets. 1 As last year's International Capital Markets report analyzed, a substantial buildup in derivatives credit exposures and leverage contribut...
