APPENDIX D (Atmospheric Pressure Input Data & Output Requirements) Figure D-1 below provides a sample of the actual contents within the input file (e.g. pressure.txt), storing the atmospheric pressure input data, for each grid area in the map. Note : due to lack of "vertical space" on this page, the entire content is split across Figures D-1a, D-1b and D-1c. In reality, the data in all 3 figures are combined and stored in a single input file!

Student's INPUT Data (in graphical form) Forecasted Pressure Level (%) for EACH Grid Area Referring to the FIRST LINE shown in earlier Fig. D-la, the grid area [0, 0] has a pressure value of 36, which is shown here. 56 82 39 3B 25 23 83 78 7 41 38 47 39 69 50 90 24 80 6 56 6 10 18 6 83 5 86 40 5 62 83 11 59 78 40 51 50 73 4 9 85 79 15 47 65 63 78 Referring to the FIRST LINE shown in earlier Fig. D-1b, the grid area (0,4) has a pressure value of 15, which is shown here. 3 64 27 15 13 84 40 42 77 18 N 38 27 17 33 58 35 42 63 71 A 1 32 65 42 86 54 36 59 53 32 36 72 53 1 6 5 27 36 70 1 2 3 5 6 7 8 Fig. D-2 Note : a) Bright Yellow grid areas indicate the ACTUAL Grid Area Sccupied by a particular city. For example, in the fig. D-2 above, the city named "Mid_City" occupies the following grid areas: [2, 7), [2, 8), (3, 7), (3, 8] b) Light Yellow grid areas indicate the grid areas surrounding the perimeter of EACH city.

As a result, they are not included in the AP computation (see below) as well... c) For each city, the AVERAGE PRESSURE (AP) value is derived, by the following: AP = SUM (cloud cover values of city + surrounding grid areas) / Total # of grid areas For example, for the city named "Mid City": AP = ((47 +39 +39 +38) + (6 +38 +82 + 10 + 16 + 68 + 69 +25))/12 = 39.75 Processing requirements - display atmospheric pressure map (pressure index) Figure D-3 below illustrates the actual display formatting requirements when user selects the "Display Atmospheric Pressure Map (pressure index)" option from your program's menu. vmw_ubuntu@vmwubuntu: -/TEMP/CSC1251/Assn 1 Note: 8 7 5 4 3 2 1 ###### ### # # # # # # # # # 5 8 3 3 2 2 8 3 7 # 4 3 4 3 6 5 9 2 8 # 5 1 1 8 8 4 # 6 8 1 5 7 4 5 5 7 # 8 7 1 4 6 6 7 2 2 1 1 8 4 4 7 1 3 2 1 5 3 4 6 7 3.6 4 8 5 3 5 5 3 # 3 2 7 5 1 5 2 7 ### # # # # # # \1 2 3 4 5 6 7 8 #### (1) All the cloud cover input values (shown in Fig. D-2) has been reduced to a SINGLE-DIGIT "pressure index" value ranging from 0 to 9!
