Discussion of Environmental Conditions 



Environmental factors, including average temperatures 

 and precipitation levels, play an important role in the pro- 

 duction and deterioration of icebergs. The weather condi- 

 tions for the last quarter of 1981 were slightly warmer than 

 normal throughout Newfoundland and Labrador. Rainfall 

 totals were above normal through the end of the year. The 

 arrival of 1982 brought colder weather with below normal 

 temperatures (Table 4) being recorded throughout the pro- 

 vince for the first six months of the year. The summer 



months had scattered weather patterns without any signifi- 

 cant temperature or precipitation trends developing. Major 

 environmental conditions for the 1982 International Ice 

 Patrol season, from several stations throughout New- 

 foundland and Labrador, are listed in Table 4. The four sta- 

 tions are Hopedale, Labrador (55°25'N, 60°10'W); Goose, 

 Labrador (53°25'N, 60°20'W); Gander, Newfoundland 

 (48''55'N, 54''35'W); and St. John's, Newfoundland (47°35'N, 

 52°40'W).
