Assignment 6 



Watch Routines (Continued) 



Text: Pages 193 - 248 



Learning Objective: Recognize the 

 procedures used to plot weather 

 information ashore and afloat and 

 the position of weather elements 

 around the station circle. 



6-6. Which of the following is the source for 

 encoding instructions for synoptic obser- 

 vations made at land stations and ship 

 stations? 



1. Chapter 21, AG 3 & 2, NAVEDTRA 10363-E 



2. FMH No. 2, Synoptic Code (NA-50-ID-2) 



3. Manual for Synoptic Code (NA-50-ID-506) 



4. FMH No. 6, Upper Wind Codes 



6-1. When you plot a surface synoptic chart, 

 which of the following is the most 

 important? 



1. Neatness 



2. Accuracy 



3. Speed 



4. Discarding erroneous reports 



6-2. The maps and charts plotted at any given 

 weather station are determined by all but 

 which of the following? 



1. Geographical location 



2. Area of responsibility 



3. Operational requirements 



4. Present weather conditions 



In items 6-3 through 6-5, refer to figure 11-1 of 

 your textbook. Select from column B the station 

 circle position in which each weather element 

 listed in column A will be plotted on a land 

 synoptic map. 



In items 6-7 through 6-9, refer to figure 11-3 in 

 your textbook. Select from column B the station 

 circle position in which each weather element 

 listed in column A will be plotted in shipboard 

 code plotting.
