New York Weather Burbau.

The following table furnishes a comparison between the tem- 

 perature of northern New York as a whole, and other points of 



the globe having similar conditions: 



Table 5. 



The Mohawk Valley. 



The prevailing winds of this deep depression between the high- 

 lands of northeirn and central New York are almost exclusively 

 easterly and Vv^esterh^, following the general course of the valley. 

 Its temperature conditions are but little known from observation, 

 excepting at Utica, which represents the cold section of the 

 region. The winter temperature is here considerably below that 

 at points of the Lake Eegiou to the westward having substan- 

 tiallv the same latitude and elevation, and differs but little from 

 that of the highlands toward the south. The explanation of this 

 peculiar condition lies partly in the exposure of Utica and its 

 vicinity as; far west as Palermo to northerly winds which have 

 not passed over any poi^tion of Lake Ontario ; and also in part to 

 the nocturnal downflow of air from the adjacent hills, to be re- 

 ferred to later. The summer temperature of Utica is, very nearly^, 

 that of the Lake Eegion. 



Statements which the writer has received from persons familiar 

 with the regioui of the Mohawk show tliat, in passing eastward, 

 no substantial variation from the above conditions is met with 

 until ithe valley broadensi out in the central or eastern part of 

 Montgomery county. Here the temperatures are similar to those 

 of the adjacent portion of the Hudson valley; the latter being ap- 

 parently rather the cooler iregion ini summer, owing to its greater 

 exposure to noi'therly winds.
