Description :
An objective hybrid classification of daily surface weather maps for Churchill, Manitoba, was used to determine the dominant synoptic conditions during the snowmelt and snow-free periods for the Canadian central subarctic. This classification yielded different dominant synoptic types for the two normal (1996, 1997) and one El Niño (EN), (1998), seasons. The synoptic patterns that emerged were then related to the precipitation and surface evaporation regimes of a subarctic sedge fen typical of the northern Hudson Bay Lowland subarctic region.
