- ShareWare...
-
- This program is distributed as ShareWare. You may fell free to copy and
- revise it as you like as long as you do not remove or alter any of the
- credit information located in lines 1-200 and elsewhere in the program.
-
- You are welcome to revise, add and make improvements to this program. If
- you find that you have made some significant improvements and additions
- to this package, please upload them to my attention either at The Mailroom
- RBBS or to Compuserve; User # 76044,1535.

-
- Whats New With This Version...
-
- - Dew Point Calculation! Dew point is "backed" into given the current
- temperature and relative humidity.
-
- - Basic source code has been cleaned up and better organized into
- subroutines to allow for easier interpetation of the modules and
- possible refinement by the end users. REMarks clearly indicating
- all major areas of the program have been added.
-
- This housecleaning of the source code will eventually allow the
- program to take on a great deal more "practical" uses building
- on the existing information already supplied and calculated in
- the existing modules with relative ease.
-
- - Heat Index and THI quick explanation pages have been added as a
- user selectable option to give a more immediate interpretation
- of the results of these two calculations from within the program.
-
-
-
- ~~~~~~~~~~~~~~~~~~~
-
-
- Whats Included In The Package...
-
- - This quick reference documentation file.
-
- - The actual BASIC source code for the program itself.
- This is an actual IBM/MS BASIC program and can be
- run under the BASIC interpreter by typing:
-
- BASICA WX43
-
- At the DOS command prompt. [ Be sure that BASICA is available
- either on the current disk or through an appropriate PATH. ]
-
- - An EXEcutable, compiled, version of the program which can be
- easily run from the DOS command prompt by typing WX43.
-
- - You will find that the compiled version is somewhat faster.
-
- - A comments form. Your feedback on this program and it's future
- direction is appreciated. If you are unable to submit feedback
- and suggestions to either CompuServe or The MAILROOM RBBS, please
- a moment and jot your ideas down here. Thank you.

- The Weather Modules...
-
- Forecasting:
-
- Given the barometric pressure and temperature, this module will predict the
- weather for your area for approximently the next 24-48 hour time period. It
- is sometimes necessary to advise the program as the whether the pressure is
- rising, falling, or steady; and whether or not the tendancy is moving rapid
- ly or slowly. The wind direction coupled with the barometric information
- may at times require knowledge of the previous wind direction to make an
- accurate prediction.
-
- This forecasting module uses the most detailed of the "Wind-Barometer"
- tables as its guide. It produces a fairly accurate forecast when supplied
- with the proper information. Test it against your weather station.
-
- This module does not take into effect the altitude, prevailing winds, or
- normal standard cyclical barometric changes.
-
-
- Wind Chill:
-
- This module computes what it really feels like outside to the average
- person dressed in an average mannor. Wind has a profound effect upon the
- effective temperature. Stronger winds make it appear to be much colder
- and harmful than light winds.
-
- Wind chill calculations are most effective under 60 degrees and less effect
- ive over 60 degrees. Use this calculation to se how "cold" it really is.
-
-
- Temperature-Humidity Index:
-
- This module calculates an index number which basically tells you the exact
- opposite of Wind Chill; how uncomfortable it really is due to the effects
- of heat and humidity. THI figures in excess of 92 are considered VERY
- DANGEROUS. The internal interpretation page within the program tells more.
-
-
- Heat Index:
-
- This calculation is very similiar to the THI except that it calculates a
- number that may be more understandable. Ibstead of producing just an index
- number, it returns the actual temperature which it feels like. Temperature
- readings in the 90's with high humidity actually make it feel like it is
- over 150 degrees and extreme caution should while outdoors!
-
-
- Dew Point:
-
- The Dew Point module calculate the temperature at which, given no change in
- barometric pressure, the air will become "saturated" and "dew" or conden-
- sation would begin to form. Watch for a high dew point to indicate whether
- or not to attempt observational astronomy (with dew, the lens will frost
- over and fog may occur) as well as for a great number of other items.
-
- Hint..when the dew point and the temperature are the same, the cloud base
- is ground level. You're in them! And condinsation of some form will occur.

-
- Future Directions...
-
- Given the amout of information which is already available from either the
- input required for these modules and as a result of the modules themselves,
- there are any number of routines which could now be implemented to better
- take advantage of the data. Programs relating to predicted wind speed,
- cloud formation, fog, etc...
-
- Additionally, the forecasting module could be revised to take into account
- some additional variables such as altitude, prevailing wind presence, the
- normal daily cyclical movement of the barometer, etc. This could become
- an additional subroutine which would let those interested in a more pro-
- fessional forecast and knowledgable enough to utilize it continue, while
- leaving the base program module informative and simple for those who wish
- not to go on.
-
- More detailed, immediate branching, subroutines could be added to better
- explain and advise on the individual subroutines as has been attempted in
- the THI and Heat Index modules.
-
- A "Testing" routine could be entered to help guide those who would like to
- test themselves and their weather knowledge by supplying just some of the
- information and prompting for answers.
-
- Your ideas and additions are welcome!
