2 Meteorology 



This chapter summarizes the meteorological measurements made during 

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

 measiu-ements 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 firequentiy. Meteorological data are simimarized 

 in Table 2.
