Analysis and Specification of Slant Wind Shear


Book Description

Wind data have been analyzed to produce frequencies of occurrence of slant wind shear with respect to surface wind speed, time of day, vertical temperature gradient and wind shear direction differences. Slant wind shear (SWS) is a measurement that more closely approximates the shear encountered by an aircraft on takeoff or landing. It is computed as the wind shear between a higher level wind (in this study, 60 m) and the surface separated by a horizontal distance equivalent to that which an aircraft would traverse in descending or ascending that height. Additional study was also completed on the specification of slant wind shear along the runway through the use of an offset towersurface site system.







A Voyage to the North West Side of America


Book Description

James Colnett, a veteran of James Cook's second voyage to North America, was an early participant in the maritime sea otter trade. Between 1786 and 1789 his two-vessel expedition traversed the Northwest Coast from Prince William Sound to Vancouver Island and wintered on the Hawaiian Islands. Along the way, he and his crew had some remarkable encounters with Native peoples of the Northwest Coast and the Hawaiian Islands: they were the first Europeans to encounter the Tsimshian and the southern Heiltsuk peoples as well as the first to land on the southern Queen Charlotte Islands. Colnett's journal of this expedition is published here for the first time. Editor Robert Galois provides extensive annotations, along with an introductory essay addressing the geopolitical context of the voyage and the intellectual background that shaped the writing of the journal. Galois supplements Colnett's writings with extracts from a second journal -- also previously unpublished -- by Andrew Bracey Taylor, third mate on one of the ships under Colnett's command. Also included are illustrations from Colnett's journals and a variety of maps, both contemporary and historical. This fascinating and informative account offers a new understanding of the early European presence in the Northwest and of Native responses to these developments. It will interest historians, geographers, and ethnographers of the Northwest Coast and beyond.
