These should be copied into the same directoty on your hard drive. The first is the actual program (i.e., 

 executable), and the second is a flat-ASCII data file read by the program. Double-click on the BAION icon (or 

 cUck on the "START" button on your WINDOWS toolbar, then "RUN...", then enter die path name for 

 BAION in the dialog box). The MS-DOS window will appear displaying the BAION starting banner. 



At this point, the program will display a figure showing a circle embedded in a square. You may see an ellipse 

 embedded in a rectangle. If so, you will need to adjust the display of your monitor, by using the controls on the 

 rim of the monitor frame. (Many machines will retain these adjustments in memory, and automatically 

 implement them whenever the same program is activated.) Program operation will resume when you press any 

 key. 



The computer will ask for a starting date for the display. For now, you can simply press ENTER, and the 

 display will start at the beginning of the record. Later, you can enter a specific date by using the format 

 YYDDD. You will be prompted for any changes to the plotting scales for the display (answer "no" for now) 

 and then you'll be prompted for assurance that the display should continue (answer "yes"). (The program is 

 rather insecure, and needs frequent encouragement.) 



Now the data display wiU (hopefully) begin. AH controls on the program are effected by the keyboard. The 

 bottom line of the display panel summarizes the controls available to the user: 



S - slows the rate of the display by inserting a delay between plotted points, can be pressed successive 



times to further slow the display (but see also "P") 

 A - accelerates the rate of display by decreasing the time delay between plotted points 

 P - "pause" or "point" display, holds the present display; each time "P" is pressed an additional point is 



displayed 

 R - resumes the default display rate, can be used to cancel the effect of "P" 

 X - refreshes the axes on the wind panel 

 L - allows the user to re-scale displays while in progress 

 Q - terminates the present display 



There are three panels in which various data are shown (Figure 1). The panel at the lower left indicates 

 meteorological and astronomical controls. The daily-averaged vector-mean wind velocity is shown as a line 

 element terminated by a small circle. (Arrowheads are too hard to plot.) The length of the line segment is 

 proportional to the speed of the wind (the circle indicates 10 m/s) and the orientation of the segment is the 

 direction to which the wind is flowing. In the example of Figure 1, the wind blows from SE to NW. 



Data from two locations in the region are shown. The yellow vector is representative of the north shore of 

 Corpus Christi Bay. This is primarily the record from the CBI Ingleside anemometer, which is the earliest such 

 record from the project region, beginning in late Jime 1992. Unfortimately, the data record terminates in 

 December 1996. For the remainder of the period of display (through 31 December 1999), data from the 

 Port Aransas anemometer is used. The combined record is therefore referred to as "North Bay." In July 1994, 

 a red vector is added to the wind display: this is the data record from the Naval Air Station, characterizing the 

 south shore of Corpus Christi Bay. There are frequent gaps in both anemometer records, so the redundancy of 

 two data sources is useful. fThese also display the differing responses of the wind depending upon whether it 

 blows over land or water.) 



The lower left panel also shows the lunar controls, depicting lunar aspect as a moving icon. The appearance of 

 the icon shows phase of the moon (in Figure 1, the crescent). The vertical (y-) component of the position of 

 the icon is the declination of the moon, and the horizontal (x-) component is an index of the proximit)' of the 

 moon to the earth, the line marked "apog" corresponding to greatest distance ("apogee") and the line marked 

 "perig" to smallest distance ("perigee"). The 12.4 and 24.8-hr tidal components are virtually eliminated by the 

 24-hr averaging to which this data has been subjected. The lunar controls on ride are not, therefore, so obvious 

 as when intradaily data are shown, but the lunar declination does account for some of the 15-day oscillation. 



Two other panels are shown on the right two-thirds of the screen. The lower of these displays water levels. 

 There are three sites displayed: the CBI White Point tide gauge, the water level of Corpus Christi Bay, and the 

 water level at the Rincon diversion USGS gauge. Corpus Christi Bay is the tide record from the CBI Aquarium 

 gauge, with older records filled in from the CBI Ingleside gauges, vit^
