Seasonal forecasts of North Atlantic tropical cyclone activity in the North American Multi-Model Ensemble
The North American Multi-Model Ensemble (NMME)-Phase II models are evaluated in terms of their retrospective seasonal forecast skill of the North Atlantic (NA) tropical cyclone (TC) activity, with a focus on TC frequency. The TC identification and tracking algorithm is modified to accommodate model data at daily resolution. It is also applied to three reanalysis products at the spatial and temporal resolution of the NMME-Phase II ensemble to allow for a more objective estimation of forecast skill. When used with the reanalysis data, the TC tracking generates realistic climatological distributions of the NA TC formation and tracks, and represents the interannual variability of the NA TC frequency quite well. Forecasts with the multi-model ensemble (MME) when initialized in April and later tend to have skill in predicting the NA seasonal TC counts (and TC days). At longer leads, the skill is low or marginal, although one of the models produces skillful forecasts when initialized as early as January and February. At short lead times, while demonstrating the highest skill levels the MME also tends to significantly outperform the individual models and attain skill comparable to the reanalysis. In addition, the short-lead MME forecasts are quite reliable. At regional scales, the skill is rather limited and mostly present in the western tropical NA and the Caribbean Sea. It is found that the overall MME forecast skill is limited by poor representation of the low-frequency variability in the predicted TC frequency, and large fluctuations in skill on decadal time scales. Addressing these deficiencies is thought to increase the value of the NMME ensemble in providing operational guidance
Ontario’s K-12 International Education Strategy: Policy Impacts on Teacher Education for International, Intercultural and Multilingual Sensibilities
While the need to internationalize teacher education is recognized by scholars/practitioners, little attention is paid to the role of policy/policy-makers in supporting this endeavor. This chapter focuses on the enactment of Ontario’s K-12 international education strategy by four key policy actors: the Ontario Ministry of Education, the College of Teachers, School Boards and Faculties of Education in realizing (or not) the internationalization of teacher preparedness. A siloed approach, conflict in policy messaging, overlooked policy alignments and weak policy framing result in diminishing the relevance and importance of internationalization of teacher preparedness to meet Ontario’s international education objectives.https://source.sheridancollege.ca/nonfaculty_cei_books/1005/thumbnail.jp
