the gale of the 14th abated than another disturbance was located 

 about 250 miles south-southeast of Sable Island. It had been lost 

 on the Weather Bureau's synoptic map, when it passed out to sea 

 off the Virginia coast the 15th, but the ice patrol was able to plot its 

 position quite accurately from a number of ship reports scattered over 

 a large area. The winds accompanying this disturbance backed 

 through the northeast, showing that the storm was passing to the 

 southward of us and by the 17th the wind had weakened to a moderate 

 breeze from the northwest, with fine weather again. The path of the 

 cyclone is shown as track B on the weather map for the month. 

 (See fig. 11.) 



An anticyclone of expansive proportions followed closely in the 

 rear of this disturbance, bringing northwesterly winds, high pressure 

 and fine weather, the 18th, 19th, and 20th, but on the 21st, and 22d a 

 general lowering of the barograph ushered in summer-time conditions, 

 a shift of wind to the southern quadrant, and plenty of fog for the 

 ice regions. 



The first week of June was characterized by a large anticyclone 

 and clear weather favorable for ice scouting. The second week low 

 pressure over northeastern North America and high pressure in the 

 region of Bermuda, gave southerly winds to the Grand Bank and 

 much fog. The third and last week the patrol was in the ice regions 

 we experienced two disturbances, one of which followed a track south 

 of the Banks. There were two days during the month when the wind 

 attained gale force. There was 33 per cent hours of fog and 43 per 

 cent hours of fog and low visibility. 



SUMMARY 



The season's summary reveals the following facts: Probably the 

 most outstanding meteorological event of March, at least for the 

 patrol, w^as the passage of a severe storm center directly across the 

 position of the Tampa southeast of Sable Island; the barometer record- 

 ing a minimum of 28.96 inches. April 7 to 16 witnessed a general 

 stagnation in the usual march of the "highs" and "lows," but the 

 most important weather characteristic of April was the prevalence 

 of anticylco.:ic conditions over Nova Scotia and Newfoundland, 

 .resulting in an abnormal percentage of easterly and northeasterly 

 winds. May saw families of cyclones, and changeable weather up 

 until the 8th, followed by a period of 11 days when a summer-time 

 distribution of atmospheric pressure brought the first really long spell 

 of fog. Gales and strong winds ushered out the month. June 7 to 14 

 there was a resumption of lov/ pressure over North America and a 

 return of the blanket of fog to the cold waters around the Grand Bank. 

 The normal monthly percentages of fog based on 7 consecutive years 

 of patrol records are: April, 24 per cent; May, 28 per cent; and June, 

 38 per cent. There was only one-half the usual amount of fog during 

 72092—27 4
