2 Meteorology 



This chapter summarizes the meteorological measurements made during the current year and in 

 combination with all previous years. Meteorological measurements during storms are given in 

 Chapter 9. 



Mean air temperature, atmospheric pressure, and wind speed and direction were computed for 

 each data file, which consisted of data sampled two times per second for 34 min every 6 hr beginning 

 at or about 0100, 0700, 1300, and 1900 hr eastern standard time (EST); these hours correspond to the 

 time that the National Weather Service (NWS) creates daily synoptic weather maps. During storms, 

 data recordings were made more frequently. Meteorological data are summarized in Table 2.

Air Temperature 



The FRF enjoys a typical marine climate that moderates the temperature extremes of both summer 

 and winter.
