U.S. Weather Atlas for Windows
copyright 1995, Salt Creek Software
The U.S. Weather Atlas provides monthly weather averages for over 100
U.S. cities. For each city, you can display graphs of high/low tempera-
tures, sunshine, rainfall, snowfall, humidity and sunrise/sunset times.
Up to 3 cities can be selected on the same graph for side-by-side
comparison.
Installation:
To automatically install the Weather Atlas on your Windows 3.1 or WIN95
system, run the "setup.exe" program. The application files may also be
copied and installed manually - no uncompression or other file
manipulation is required.
Registration:
The U.S. Weather Atlas is being distributed as shareware. It may be
freely copied, distributed, and posted on public networks provided the
program is not altered in any way and is always accompanied by this
text file ("uswthr.doc").
If you plan to keep this software, please register with us. The
registration fee is only $ 10.00 (U.S.). You will receive an update
diskette containing the most recent version of the U.S. Weather Atlas,
plus a BONUS program "World Weather Atlas for Windows" - temperatures,
rainfall and humidity for 70 cities worldwide.

Following are instructions for the Weather Atlas. This information is
also available in on-line Help:
-----------------------------------------------------------------------
Weather Graphs
Weather averages can be displayed for up to 3 cities at a time. To
select a city, click the mouse on its location on the U.S. map.
(Clicking the city again will de-select it.) Or, using the keyboard
or mouse, select the city from the listbox under the "File | City List"
menu. Cities are listed alphabetically by state.
Use the "Options" menu to select the weather element to be plotted, or
just click its icon on the options toolbar. Supported data types are:
Temperatures (avg high/low), Sunshine, Rainfall, Snowfall, Relative
Humidity, and Sunrise, Sunset times.
Cities and graph types can be changed at any time. If 3 cities are
already displayed, selecting a fourth will automatically scroll the list,
removing the first city. Selecting "Options | Clear", or clicking the
Clear icon, will erase the current graph and remove the active city list.
If you would like to display just the graph, select the "View | Graph
Only" menu. You will still be able to add cities to the graph in this
mode, but the cities must be selected from the listbox. To return to
the original display mode, select the "View | Map + Graph" menu.
Once a graph is displayed, you can write the associated monthly data to
a text file using the "File | Write data to file" menu (not applicable
for sunrise / sunset charts). The current display can be sent to the
printer or copied to the Windows Clipboard at any time, using the "File"
menu or the toolbar. To get the best printouts, put the display in
Graph-Only mode, and resize the window to the size needed (the graph
will scale automatically to fit the window size).
Monthly Maps
The Monthly Maps window gives you a "big picture" look at the city data
used for the weather graphs. To pop up this window, select the monthly
map icon from the toolbar or the "Options | Monthly Maps" menu.
A map of the mainland U.S. will be painted, using a different color for
each data range. The initial data display will be for January: use the
radio buttons to select other months and weather elements.
Background Information
The data used to generate the weather graphs in this software were
obtained from the National Oceanic and Atmospheric Administration (NOAA -
U.S. Department of Commerce). The averages are based on observations
made over a 30 - 60 year interval... the exact interval varies with
different cities and weather elements.
The "average sunshine" option refers to the total time that sunlight
reaches the ground, expressed as a percentage of the maximum possible
from sunrise to sunset.
The "rainfall" numbers include liquid water equivalent of snow, sleet
and hail.
NOAA includes hail and sleet in the "snowfall" totals.
"Relative humidity" is the amount of moisture in the air as a percentage
of the maximum the air can hold at the current temperature. Warmer air
holds more moisture than cool air, so the relative humidity is usually
greatest in the early morning and lowest in mid-afternoon. The data
used in this software are all afternoon readings.
Sunrise/set data: Sunrise and sunset times come from standard tables.
Daylight Savings Time, which starts in early April and ends in late
October, is accounted for in all charts. Areas which don't observe
DST (Arizona, central Indiana, and Hawaii) will not show the usual
"jump" in sunrise/sunset times in April and October.
