" For the Málwa plateau we have curves for Nasirabad, April to December ; for Neemuch,
January to August ; and for Mhow, the full year. At these three stations, so far as the curves
show, the wind is westerly from March to October and easterly from November to February,
the maximum westerly coefficient belonging to the middle of the monsoon and the maxiinun
easterly to near midwinter. But Mhow has also a considerable south duration component
in all months except January, and on the other hand the monsoon winds of Nasirabad have
an abnormal north duration component, being nearly due west instead of considerably south
of west, as is the case at Neemuch and Mhow.
" For the Deccan we have curves for the full year for Kirkee, Poona and Belgaum, and
incomplete curves for Ahmednagar and Kolhápur. At all these stations westerly winds attain
their maximum of duration in the middle of the monsoon, and so far as the curves show,
easterly winds near midwinter. Generally the monsoon winds deviate but little if at all to
the south of west. The months in which easterly winds prevail are at Kirkee, December ; at
Poona, October to January ; at Belgaum, October to March.
" Of the curves of the stations in the Konkan, that of Bombay is almost an exact counter-
part of that of Deesa. The curves of Goa and Belgaum-—the latter place about 50 miles to
landward of the former and on the Deecan plateau—show that the same winds have the same
degree of preponderance at both places in the months May to September, but for the
remaining months of the year the prevalent winds of Belgaum have an east duration
component.
" At the hill stations both of the Deccan and Konkan and also at Kolhápur the monsoon
winds are decidedly from the south-west and with large coefficients. The easterly winds of
the winter have larger coefficients and prevail longer than in the plains of the Konkan ; and
the extended prevalence is greater as we proceed eastward, for at Purandhar easterly winds
prevail from October to April, at Mahábaleshvar and Mátherán from October to January,
and at Goa and Bombay only during December and January,

The humidity of the air varies greatly in the different stations. In the coast
stations (Karachi and Bombay) tbe air is laden with moisture all tbe year round ;
but in Malwa, Rájputána and the Deccan scorchingly hot and dry winds prevail
during the hot season which, abstract a very considerable quantity of humidity
from the air.
The highest annual average humidity is found at Bombay, but in Belgaum
it is very high,—in fact at that station the air during the months of July and
August is within eleven points of saturation.
The subjoined table showing the average mean monthly and annual relative
humidity of tbe following stations is taken from tbe Report of the Meteorological
Reporter with the Government of India for 1880 :—
