System Description:
|
|||
|
|
|
|||
|
|
The IBM-PC Forecasting System is an automated weather forecasting
|
|||
|
|
package derived from the Sager Weather Forecaster handheld manual computer.
|
|||
|
|
Forecasts computed by the system should be fairly accurate for about
|
|||
|
|
a six to twelve hour period. However, as time goes on the forecasts
|
|||
|
|
tend to be less accurate. You may be suprised, though, how close the
|
|||
|
|
forecasts are to the TV news forecasts.
|
|||
|
|
|
|||
|
|
The software was written in Turbo Pascal and should work on any IBM-PC
|
|||
|
|
compatible system. The source code is listed as 'FORECAST.PAS'.

Input Required:
|
|||
|
|
|
|||
|
|
1. WIND DIRECTION: Wind direction should be two alphanumeric characters
|
|||
|
|
that represent one of eight wind direction vectors.
|
|||
|
|
|
|||
|
|
N = NORTH
|
|||
|
|
NE = NORTHEAST
|
|||
|
|
E = EAST
|
|||
|
|
SE = SOUTHEAST
|
|||
|
|
S = SOUTH
|
|||
|
|
SW = SOUTHWEST
|
|||
|
|
W = WEST
|
|||
|
|
NW = NORTHWEST
|
|||
|
|
|
|||
|
|
|
|||
|
|
2. BAROMETRIC PRESSURE: The barometric pressure at sea level in
|
|||
|
|
inches of mercury.
|
|||
|
|
|
|||
|
|
29.95 = Twenty-Nine point Nine Five Inches of Mercury
|
|||
|
|
|
|||
|
|
|
|||
|
|
3. PRESSURE TENDENCY: Pressure tendency is the current tendency of the
|
|||
|
|
barometric pressure.
|
|||
|
|
|
|||
|
|
R = RISING
|
|||
|
|
RR = RISING RAPIDLY
|
|||
|
|
N = NORMAL
|
|||
|
|
F = FALLING
|
|||
|
|
FR = FALLING RAPIDLY
|
|||
|
|
|
|||
|
|
NOTE: It is normal for the pressure to rise in the morning and fall
|
|||
|
|
in the afternoon. This cycle is repeated during a 24 hour
|
|||
|
|
period.
|
|||
|
|
|
|||
|
|
|
|||
|
|
4. SKY CONDITION: Sky condition is the condition of the atmosphere. The
|
|||
|
|
possible conditions are:
|
|||
|
|
|
|||
|
|
CLEAR = CLEAR SKIES
|
|||
|
|
PCLOUDY = PARTLY CLOUDY SKIES
|
|||
|
|
MCLOUDY = MOSTLY CLOUDY SKIES
|
|||
|
|
CLOUDY = CLOUDY SKIES
|
|||
|
|
PRECIP = RAIN, SLEET, SNOW, ETC. (PRECIPITATION)
|
|||
|
|
|
|||
|
|
|
|||
