REMARKS. 



The month of November has been one of marked barometric activ- 

 ity and thi)ugh the areas of barometric depression have predominated, 

 accompanied h}' a large percentage of clondiness (62%), high rela- 

 tive humidity (80.5%) and heavy rainfall (5.36"; the mean barom- 

 eter (30.187") and range of pressure (1.45") have been unusually 

 high for this station. 



These fluctuations in the atmospheric pressure have in general 

 been very marked and sudden. Between Oct. 30th, 10 a. m. and 

 Nov. 1st, 3 A. M., 17 hours, the barometer fell .94 of an inch ; from 

 12 p. M. Nov. 21st, to 9 A. M. 22d, 33 hours, it rose 1.34 inches or 

 1.05 inches from midnight to midnight on the 21st; and .8 of an 

 inch from 7 : 30 p. m. on the 26th to 12 : 30 m. on the 27th, 17 hours. 



"There were only six anticyclones spreading near enough to us to 

 influence the weather, while nine ■ cyclones gave us part of their 

 clouds and moisture. Of the latter five pass«^d easterly to the north 

 of us and three moved up our eastern coast. Three of those that 

 passed to the north came from the southwest, and moved with in- 

 creasing energy up the Mississippi and Ohio valleys to the Lakes 

 drawing in large volumes of warm moisture-laden air from the 

 Southern latitudes, and so aiding in increasing our precipitation and 

 making the temperature for the mouth average from two to three 

 degrees a day higher than usual. Two of these storms passed by to 

 the north of us at about midnight and were then followed by a shaip 

 cold wave with rising barometer." 



The mean temperature (41.1") for the month has been about two 

 degrees above tlie normal. 



The wind storms have in general been moderate and of short 

 duration. Those accompanying the storms of the 21st and 26th 

 instants,— so serious in the West, — were however more severe, regis- 

 tering velocities of 67 and 58 miles respectively at their maxima. 



An unusually heavy fog was observed on the evening of the 19th 

 instant.
