SUMMARY In   this   chapter,   we   have   discussed   selected significant  weather  warnings  and  sea  advisories.  The importance of verifying these warnings and advisories was also presented. Means for forecasting evaporative ducts and altimeter settings was then presented. We also discussed how aerosols in the atmosphere affect EO sensors,  weapons,  and  communications.  We  discussed WEAX and AVWX formats as well as procedures for obtaining  them. We  listed  publications  used  in identifying ship-class radars, and then discussed a means for obtaining aircraft ditch heading products. Next,  we  discussed  the  importance  of  verifying  TAFs, OPARs, HWDs, and AIRMETs and SIGMETs. Finally, we outlined the various climatological publications, their content, and a means for obtaining them. 10-12
