[Review of] Constance Wall Holt. Welsh Women: An Annotated Bibliography of Women in Wales and Women of Welch Descent in America
To be a Welsh woman, it seems, was to be doubly doomed to obscurity. Not only were women a less-public sector of society, but there was Welshness to contend with. It has been a case of Bibliographic Ethnic Discrimination. Too often entries have read: Women, Welsh, See Women, English. And this occurs in spite of the fact that Welsh, being Celts, are a distinct group with their own language and culture, though they have long been subject to English rule
A three dimensional finite element model of wind effects upon higher harmonics of the internal tide.
A non-linear three dimensional unstructured grid model of the M2 tide in the shelf edge area off the west coast of Scotland is used to examine the spatial distribution of the M2 internal tide and its higher harmonics in the region. In addition the spatial variability of the tidally induced turbulent kinetic energy and associated mixing in the area are considered. Initial calculations involve only tidal forcing, although subsequent calculations are performed with up-welling and down-welling favourable winds in order to examine how these influence the tidal distribution (particularly the higher harmonics) and mixing in the region. Both short and long duration winds are used in these calculations. Tidal calculations show that there is significant small scale spatial variability particularly in the higher harmonics of the internal tide in the region. In addition turbulence energy and mixing exhibit appreciable spatial variability in regions of rapidly changing topography, with increased mixing occurring above seamounts. Wind effects significantly change the distribution of the M2 internal tide and its higher harmonics, with appreciable differences found between up- and down-welling winds, and long and short duration winds due to differences in mixing and the presence of wind induced flows. The implications for model validation, particularly in terms of energy transfer to higher harmonics, and mixing are briefly discussed
