J. Eliot — The South-West Monsoon Storms 



[No. 2, 



ISth November. — The chief feature in the meteorology of India on 

 the 13th was the cyclonic disturbance off the Burmese coast. A rapid 

 rise of the barometer during the preceding 24 hours over the Punjab 

 and Sind, completely obliterated the barometric depression in that area. 

 Pressure was highest over the Indus valley, where it slightly exceeded 

 30*15". The barometer had also risen in the Central Provinces, Bombay, 

 and Madras, but had decreased in Bengal and Arakan. Hence pressure 

 diminished from west to east, and was lowest at Diamond Island, where 

 it was 29-826". 



The large depression off the Burmese coast was very distinctly marked- 

 Winds were blowing a southerly gale in the Gulf of Martaban. They 

 were easterly at Akyab, northerly in Bengal and on the Ganjam and 

 Madras coasts, thus establishing general cyclonic circulation over the 

 Bay. Elsewhere the winds were generally from the eastward, except in 

 the Indus valley, where they were northerly. 



The sky was dull and cloudy in the Punjab, and moderate rain had 

 fallen during the previous 24 hours. The sky, however, rapidly cleared 

 during the day, and was almost free of cloud by 4 p. m. Over the remainder 

 of the Indian land area, excepting Burmah, the sky was clear and the 

 weather fine. The following table gives the more important meteorolo- 

 gical observations taken at the land stations : —
