0. Little — Himalayan summer storms. 



[Ko.4, 



the increase in the west and south-west of Bengal is shown on the 11th. 

 No rain fell on the Simla Hills until the 12th and the increase in Kash- 

 mir began ou the same date. 



As in the storms in 1902, strong southerly or south-westerly winds 

 developed at Saugor Island, and generally over Northern India, showing 

 a strong indraught towards a low pressure area in the north. The con- 

 tention that no disturbance had formed over India or the adjacent seas 

 previous to these changes in the Himalayan region is supported by the 

 following quotation from the Indian Daily Weather Report of date 

 July 9th, 1903. "An important change has taken place in the distribu- 

 tion of pressure and very steep gradients favouring strong south-westerly 

 or westerly winds prevail over the greater part of Northern India, These 

 winds are, however, up to the present, diy winds and are not an extension 

 of monsoon winds from the Arabian Sea : hence no rain of any impor- 

 tance may be expected during the next 21 hours in North-West India, 

 though local dust storms may occur in that area." 



In the following table I have given the wind direction and strength 

 at Saugor Island for the two periods of disturbed weather in 1902 and 

 for the one under discussion, placed side by side for purpose of compari- 

 son. During the advance of these disturbances from the north there 

 was almost the same wind direction and strength at Saugor Island on 

 the three occasions. The direction was south-south-west almost con- 

 tinuously and there was a steady increase of velocity.

A point of interest which may be noticed in the table is in the wind 

 changes during the days 12th to 14th August, 1902, and 11th to 13th
