Synoptic/Mesoscale Meteorological Features in the Marginal Ice Zone.

摘要

This thesis summarizes meteorological conditions occurring in the Marginal Ice Zone Experiment (MIZEX-84), conducted in the East Greenland Sea during the summer of 1984, are summarized. It includes a discussion of the synoptic and mesoscale conditions. The three cases discussed are: a weak storm which filled over the marginal ice zone (MIZ); an intense storm which transited the MIZ and entered the polar basin; and an undisturbed case. The MIZEX-84 period can be divided into three synoptic time periods. The first and the last were situations when the storms passed to the south and east of the Fram Striates. During the middle period the storms passed through the straits in response to the development of a closed upper-level low over the north coast of Greenland. Three of the four storms which moved into the straits were moving north-northwest and filled or slowed significantly in the MIZ. The fourth was moving parallel to the MIZ. This would seem to show that the MIZ does not dominate but may affect storm movement. Keywords: Arctic Marginal Ice Zone. (Theses)
