Polar lows are generally short-lived but intense events that occur over cold ocean waters, poleward of a baroclinic zone. The polar low in this case formed over the open waters of Ungava Bay, in northeastern Canada, on 2 December 2000. The case is presented as a series of challenging forecast questions followed by a more traditional case study presentation. Included in this exercise is a rich set of data products and access to background materials on polar low forecasting.
