Temperature, Dew Point, and Relative Humidity - 14220_322
Wind, Continued Calculating Once  the  relative  wind  direction  and  speed  have  been  observed  and  the True  Wind ship’s  course  and  speed  recorded,  the  true  wind  can  be  computed.  The Using the True True  Wind  Computer  (CP  264/U)  is  the  quickest  and  easiest  method. Wind Detailed  instructions  on  the  use  of  the  True  Wind  Computer  can  be Computer found  in  Chapter  10  of  the  Manual  for  Ship’s  Surface  Weather Observations,   NAVOCEANCOMINST   3144.1C. Calculating True  Wind Using  the Maneuvering Board The  use  of  the  maneuvering  board  (MB)  is  by  far  the  most  accurate method  of  determining  true  wind.  The  MB  uses  exact  vectors  to establish  apparent  wind  and  own  ship’s  speed.  The  use  of  vectors makes  this  method  more  precise. Information  on  calculating  true  wind  can  be  found  in  Pub  217 Maneuvering  Board  Manual,  therefore  it  will  not  be  duplicated  here. Pub  217  also  contains  solutions  for  finding  desired  wind,  closest  point  of aproach,  and  several  other  vector  solutions  that  are  invaluable  to  the Quartermaster  assisting  the  officer  of  the  deck. Computation Check No  matter  which  method  of  computation  is  used  to  derive  the  true  wind direction  and  speed,  the  observer  should  check  the  results  by  applying the  following  rules: Rule  1:  The  true  wind  direction  is  always  on  the  same  side  of  the  ship as  the  apparent  wind  direction,  but  farther  from  the  bow  than  the apparent  wind  direction. Rule  2:    When  the  apparent  wind  direction  is  abaft  the  beam,  the  true wind  speed  is  greater  than  the  apparent  wind  speed. Rule  3:    When  the  apparent  wind  direction  is  forward  of  the  beam,  the true  wind  speed  is  less  than  the  apparent  wind  speed. 10-25
