Paper 4 



ExtratropicaL storms were concentrated from the Canadian 

 Maritimes to the Denmark Strait/ with a feu storms crossing from 

 Alaska to Greenland- 

 There were no ART flights east of Savannah/^ GAr due to tropical 

 storms. The U.S. east coast had no e xt r at rop i ca I storms this 

 months but Hurricane Belle passed from CaPe Hatteras to Long 

 Island on the 9th and ICth. The Gulf of Mexico continued 

 slightly colder than normal. It spawned the weak tropical storm 

 Dottiex which crossed the southern tip of Florida and turned up 

 the 80th meriaian to Charleston. 



S§El§.!Dfeer - Almost the entire North Atlantic surface area over 

 the shelf cooled 1C to 2C this month. The warm anomaly area 

 south of Nova Scotia expanded/ but south of AON/ and in the Gulf 

 of Mexico/ the SST's were average or slightly cooler than normal. 



The ayif^tream pictures a mildly meandering Gulf Stream for this 

 month/ with three cyclonic eddies and two anticyclonic eddies. 

 Satellite imagery intermittently pictured very complex eddy and 

 meandering activity. Cloud cover prevented proper definition/ 

 but the patterns changed rapidly through the month/ ending with 

 the quieter conditions portrayed in guilstregm. In the middle of 

 the month there were four anticyclonic eddies/ one cyclonic eddy/ 

 and one cyclonic loop. There also were large patches of 

 entrained Shelf Water and of mixed Shelf/Slope Water. One week 

 later only one anticyclonic eddy was found/ along with two 

 cyclonic eddies and the one larqe cyclonic loop. There were 

 still large patches of mixed Shelf/Slope Water/ and the the Shelf 

 Water/Slope Water front was extremely convoluted. 



The only tropical storm in September remained completely east of 

 61w. Only one storm was found relatively near the U.S. coast/ 

 and that ore was still offshore of the Gulf Stream. None crossed 

 the coast south of Newfoundland/ and most storms tracked north 

 between Iceland and the Davis Strait. In 1975/ by contrast/ 

 there were three major hurricanes; the ex t r at ropi ca I storms 

 tracked farther south and then between England and Iceland. 

 There were nc storms in the Gulf of Mexico in September 1976. 



October - The warm anomaly area south of Nova Scotia persisted/ 

 but the remainder of the Atlantic coastal area was not 

 significantly warmer or colder than norrral. The aylfstream shows 

 large areas of positive anomaly/ while the temperature anomaly 

 charts show large areas of net-ative anomaly. In the Gulf of 

 Mexico/ SST's were significantly cooler than normal. 



The Gulf Stream is pictured in au^fstresm flowing smoothly/ with 

 two major anticyclonic eddies. A cold core eddy at 32N/ 74 W was 

 entirely surrounded by warm Sargasso Sea Water which reached to 

 IOC km from Cape Hatteras. The large warm eddy at 39N/ 69w
