appropriate in the event of special incidents that may attract national and/or high-level U.S. Navy interest, and in  addition,  other  incidents  that  are  of  interest  to  the Commander, Naval Meteorology and Oceanography Command (CNMOC). Mission Impairment Incidents   impairing   mission   performance   are reported as a Unit Situation Report (UNIT SITEEP) in   the   format   of   CNMOC   3100.2,   while certain  weather-related  incidents  are  reported  in accordance with enclosure (1) of the instruction (UNIT SITREP    Weather-Related    Accidents/Incidents). COMNAVMETOCCOM  interest  is  in  incidents  causing significant and extended mission impairment that is not adequately covered by the CASREP System. Weather-Related  Accidents/Incidents We will now briefly discuss required actions in the event  of  weather-related  accidents/incidents. PURPOSE.— To notify the chain of command of weather-related/high  seas  accidents/incidents  involving ships,  aircraft,  personnel,  facilities,  or  other  resources that  may  generate  press  interest,  or  become  the  subject of formal inquiries. REPORTING CRITERIA.— A UNIT SITREP is required  when  accidents/incidents  are  weather-related or  potentially  so. Reports  are  not  desired  when accident/incidents  are  clearly  not  weather-related. For   amplifying   instructions   for   the   proper procedures  for  submitting  accurate  and  timely OPREP-3’S and UNITS SITREPs, refer to CNMOC 3100.2, as well as the instruction,  Special  lncident Reporting,  OPNAVINST  3100.6. The remaining portions of this chapter will deal with training functions associated with all METOC activities. TRAINING FUNCTIONS LEARNING    OBJECTIVES: Describe instrument ground school training for naval aviators and naval flight officers. Explain the requirement to update command local area forecaster handbooks. Review the U.S. Navy Oceanographic  and  Meteorological  Support System  Manual,  METOC  technical  bulletins, METOC   OPORDs,   and   climatology publications  for  possible  data  inclusion  in pre-deployment   briefings. In the following sections we will discuss the training functions for which the METOCs are responsible. INSTRUMENT  GROUND  SCHOOL All   METOCCENs, METOCFACs,   and METOCDETs  with  aviation  units  are  required  to annually conduct Instrument Ground School for all naval  aviators  and  naval  flight  officers. Instruction,   at   a   minimum,   should   include meteorological  parameters,  pilot  reporting  procedures, code  formats,  briefing  forms,  OPARS  forms  and procedures, NATOPS requirements, and severe weather warnings. For  further  discussion  of  minimum  content  of Instrument Ground School, refer to the instruction, NATOPS General Flight and Operating Instructions, OPNAVINST 3710.7, chapter 13. LOCAL  AREA  FORECASTER  HANDBOOKS One of the first publications that all newly reporting forecasters  should  review  upon  reporting  to  a  new command is the Local Area Forecaster’s Handbook. These   handbooks   are   an   invaluable   source   in anticipating local meteorological and oceanographic phenomena. The  instruction,   Local   Area   and   Area   of Responsibility   (AOR)   Forecaster’s   Handbooks, NAVMETOCCOMINST   3140.2,   states   the requirements   for   maintenance   of   Forecaster’s Handbooks  and  basic  guidance  on  their  form  and content. There  is  a  continuing  need  to  update  Forecaster’s Handbooks. Each command should have a program in place that continually verifies local thumb rules, as well as a program to develop new forecasting techniques. For  this  reason,  all  Forecaster’s  Handbooks  are  to  be reviewed and updated at least annually. The  Naval  Oceanographic  Office  is  now  in  the process of assembling and publishing a compendium of all   Forecaster’s   Handbooks   developed   by NAVMETOCCOM and USMC activities in compact disc-read  only  memory  (CD-ROM). For further discussion of the need and content of   the   Forecaster’s   Handbooks,   refer   to NAVMETOCCOMINST   3140.2. The forecaster will find there are a multitude of details  involved  in  the  planning  and  execution  of underway  evolutions,  as  well  as  in  the  everyday operation  of  METGCCOM  activities.  In  the  following 14-6
