On the Existence of Storm-Tracks.
Brian J. Hoskins,Paul J. Valdes +1 more
TL;DR: In this paper, the existence and possible self-maintenance of storm-tracks is investigated using a linear, stationary wave model with storm-track region forcings taken from data averaged over a number of winters.

TL;DR: It is shown that climate has been a major driver of population change over the past 50,000 years, however, each species responds differently to the effects of climatic shifts, habitat redistribution and human encroachment.
Journal ArticleDOI
Constant elevation of southern Tibet over the past 15 million years
Robert A. Spicer,Nigel Harris,Mike Widdowson,Alexei B. Herman,Shuang-Xing Guo,Paul J. Valdes,Jack A. Wolfe,Simon P. Kelley +7 more
TL;DR: It is concluded that the elevation of the southern Tibetan plateau probably has remained unchanged for the past 15 Myr, similar to the present-day altitude of 4,600 m.
