1891

The effect of the Earth's temperature on that of the air above is not so great as it is below so that this causes the amplitudes in the oscilltions of the air temperature near the Earth's surface though less than those of the Earth's surface to be greater than those of the air above. [...] But during the summer and the warmest part of the day the effect is the reverse it causes the temperatures below to differ still more from the temperatures above and hence to increase the rate of diminution of temperature with increase of altitude. [...] The paper consists of three parts ;-1st a statement of the normal meteorological temperature conditions of the plain and bill districts of Upper India in the month of January and of certain meteorological conditions and actions upon which temperature mainly depends ; 2nd a statement of the more striking abnormal temperature relations of the month of January 1889 and of the cold weather period ge [...] And if it might be assumed that the rlative intensity in the two cases is roughly speaking proportional to the ratios given in the preceding table the heating power of the sun at an elevation of 7000 foot in the Himalayas is on the average about onfifth greater than at the level of the adjacent plains or in consequence of the absorbing action of the lower strata the sun is one-sixth l [...] 1 This result is undoubtedly in part due to the greater length of the night (or period of effective terrestrial radiation) than of the day in the month of January in Northern India and perhaps also to the greater clearness and homogeneity of the atmosphere arising from the stillness of the air and absence of wind at night as compared with the day.
