Development of the MESH modelling system for hydrological ensemble forecasting of the Laurentian Great Lakes at the regional scale

Abstract: . Environment Canada has been developing a community environmental modelling system (Modelisation Environmentale Communautaire – MEC), which is designed to facilitate coupling between models focusing on different components of the earth system. The ultimate objective of MEC is to use the coupled models to produce operational forecasts. MESH (MEC – Surface and Hydrology), a configuration of MEC currently under development, is specialized for coupled land-surface and hydrological models. To determine the specific requirements for MESH, its different components were implemented on the Laurentian Great Lakes watershed, situated on the Canada-US border. This experiment showed that MESH can help us better understand the behaviour of different land-surface models, test different schemes for producing ensemble streamflow forecasts, and provide a means of sharing the data, the models and the results with collaborators and end-users. This modelling framework is at the heart of a testbed proposal for the Hydrologic Ensemble Prediction Experiment (HEPEX) which should allow us to make use of the North American Ensemble Forecasting System (NAEFS) to improve streamflow forecasts of the Great Lakes tributaries, and demonstrate how MESH can contribute to a Community Hydrologic Prediction System (CHPS).

Introductory remarks on nanodielectrics

Abstract: The neologism nanotechnology exists today and is attracting a considerable amount of interest and activity. It is complex in nature with multiple ramifications. It has a vast scope and in fact includes older as well as newer concepts. At this point in time, a greater focus on the field status and impact on new materials, especially dielectrics and their insulating properties, would certainly be desirable. A personal view is thus being presented here, with a tentative definition of the concept of nanodielectrics being offered at the end.
