PART II: METEOROLOGY 



9. This section summarizes the meteorological measurements made during 

 the current year and in combination with all previous years. Meteorological 

 measurements during storms are given in Part IX. 



10. 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 eastern standard time (EST) ; these hours correspond to the time that 

 the National Weather Service (NWS) creates daily synoptic weather maps. Dur- 

 ing storms, data recordings were made more frequently. The data are summar- 

 ized in Table 2.

Air Temperature 



11. The FRF enjoys a typical marine climate which moderates the temper- 

 ature extremes of both summer and winter.
