1884.] of the Bay of Bengal in 1883. 153 



The Log of tlie ship Mount Stuart, which was in Lat. 15° 30' N. and 

 Long. 91° 6' E. at noon, states that the sky was overcast, weather dark 

 and gloomy, and so threatening at 2 p. m. that the Captain changed her 

 course and kept away south. The Scottish Hill was 100 miles to the south- 

 south-west in Lat. 14° 8' N. and Long. 90° 33' E. at noon. The sky was 

 overcast, and frequent heavy rain squalls passed over the ship. A heavy 

 gwell from the north-east came up during the day. The weather over 

 the north-east of the Bay is described in the logs of the Ohanda, Bancoora, 

 and Mahratta. The Bancoora, in Lat. 17° 19' N. and Long. 85° 44' E. at 

 noon, had fine weather and moderate north-easterly winds of force vary- 

 ing from 2 to 4 during the day. The Chanda, in Lat. 18° 56' I^. 

 and Long. 90° 30' E. at noon, had fine weather with a hazy at- 

 mosphere, and light to moderate north-east winds. She was proceeding 

 to Rangoon, and steaming directly towards the northern quadrant of the 

 cyclone. Late in the evening, she began to experience squally weather 

 and variable winds. Frequent heavy rain squalls came up from south- 

 east and east after 8 p. m. The Mahratta proceeding from Chittagong to 

 Calcutta, and the light vessels at the entrance to the Hooghly, had fine- 

 weather, clear skies, and a smooth sea throughout the whole day. 



The meteorological data hence shew conclusively that, during the 

 24 hours preceding 10 A. M. of the 11th, a definite cyclonic circulation of 

 considerable intensity had been established to the west of the Andamans,. 

 the centre of which at noon of the 11th was probably in Lat. 13° 30' N. 

 and Long. 94° 15' E. Heavy rain was falling over and near the centre, 

 winds increased considerably in force during the day, the sea rose rapidly, 

 and gave rise to a heavy swell extending to a distance of three or four 

 hundred miles from the centre. The very rapid changes which had been 

 initiated by the cyclonic motion are indicated very clearly by the weather 

 experienced by the Satara. . 



I'Zth November. — The barometric changes of the preceding 24 hours 

 were irregular. This was in part due to the continuance of unsettled 

 weather in Upper India. The depression which had formed on the 9th 

 and 10th was filling up, and its existence was chiefly shewn on the 

 morning of the 12th by cyclonic circulation of the air in Sind, and the 

 adjacent districts of Rajputana. A smaller depression had, however,, 

 formed in the south-eastern districts of the Punjab, the centre of which 

 was at or near Lahore. This was shown by a slight fall of the barome- 

 ter at Lahore and the neighbouring stations. TJie barometer had con- 

 tinued to rise rapidly over the greater part of the Punjab, Rajputana, 

 and the Central Provinces, and over the whole of Central and Southern 

 India. A rapid fall had occurred in Burmah, and a slight one in Bengal, 

 duo to the development and extension of the atmospheric whirl in the 

 ueiglibourhood of the Andamans.
