A description is presented of physical measurements carried out on Lake Ontario during the summer of 1982. Seasonal variations of stratification and circulation are illustrated by monthly averages of temperature and current distributions in a north–south cross section of the lake. Day-to-day variations of temperature and currents are presented for three periods coinciding with biochemical investigations along the same transect of the lake. A wind-induced upwelling event followed by alongshore propagation of a warmwater wave is described and the dynamics involved are discussed.
SummaryIn the autumn of 1972 the wind-induced motions in Lake Constance have been measured simultaneously by means of self-recording oceanographical and meteorological instruments. For the case of a strong westerly wind field the process of upwelling in the western part of the lake is analysed and a detailed description of the corresponding exchange of water through the channel of Mainau at the mouth of the narrow western appendix (see Fig. 1) is given. In order to provide a quantitative interpretation of the dynamics involved the response of the lake is simulated by numerical models. The comparison of the calculated response against the measured reaction of the lake yields a considerable influence of the Coriolis force, which results in a pronounced increase of upwelling along the northern shore in that case. The response exhibits furthermore a high sensitivity to the spatial distribution of the driving force.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
