Has anyone read the novel POLAR DAY 9, by Kyle Donner? 
It's all about weather, weather modification, etc.  
It's published by Berkley Publishing group, the same company Tom Clancy
uses. 
POLAR DAY 9 is in paperback. Terrific.

"A few million years"?  That's a joke, right?  To my knowledge, carbon
dating is good for less than 50,000 years, better if less than 30,000.

Hallo;
I try to investigate a statistic of weather data (temperature, rain,
sunhoures, aso.) for Muenster in germany starting with as much history as
possible. 
Now I am searching for such kind of datas in the internet. I would be
appreciate all kind of information for internet adresses, e-mail adresse
and direct adresses to realize the weather statistic for Muenster.
My target is to do it for Muenster, but if somebody know data access from
somewhere in Germany, please let me know.
Who is able to send me these datas or adresses please contact me via e-mail
wigger@ms.tlk.com.
Thank`s for every help

Once in a while I see posts on how to obtain lightning data.  These data
sets are extremely useful, especially real-time.  I have used lightning
data operationally.   It is unbelievable how useful almost instantaneous
lightning information can be.  These data are controlled by a private
company and a few selected Weather Service Offices, mainly National
Centers pay thousands of dollars to obtain these data sets.  If you
think the taxpayers are saving money by cutting Weather Service jobs and
products, you had better think again.  Private companies are in business
to make money (rightly so).  Soemone has to pay for their services and
products.  All "free" information you find available on the Internet
these days is costing someone some time and money.

In 1974 the Federal Government created several Satellite Field Services
Stations (SFSSs).  There was an office in DCA, Miami, SFO and KC, later
ANC, NEW and Honolulu.  These offices provided around-the-clock
interpretation of satellite imagery with 6 hour messages and unscheduled
updates.  There is tremendous amount of information in a satellite
imagery.  It takes years of experience to "read" the details, like any
specialized job like reading X-rays, scanner images, etc.  It was
decided several years that the government could no longer afford the
cost of maintaining this service, so jobs were eliminated.  Now we see
pretty satellite pictures in the eyes of most people, a few try to
figure out the details.  Interpretation has gone the way of the
Blacksmith, the Caboose, etc, at least until there is an outcry for this
service again and someone can come up with the money to support it.

Pascals are the modern units of pressure in the International System of 
Units (SI).  A pascal is equal to one newton per square metre.
1 mbar = 0.1 kPa
1 inHg = 25.4 mmHg

Why do weather forcasters use the term normal? Is there anything normal
about weather? Wouldn't the term average be more accurate when comparing
current data to that of the past? ie: Today's temperature is 15 degrees
above average for this day. Rather than today's temperature is 15
degrees above normal for this day.

Dear To Whom It May Concern:
      Hello my name is De'Leisa and I am doing a research project in
school about tornadoes and I thought that if a expert on tornadoes or
simply anyone can give me any helpful information will please contact
me.My e-mail address is Lil Kim267.Please contact me as soon as possible!
      Thank You

There is a lot of confusion on this subject, even by at least some 
meteorologists, but "averages" and "normals" differ.  An average is 
simply the sum of temperatures for a given period, divided by the length 
of that period.  For example, if the sum of the high temperatures on 
January 25 in a given area for the period 1961-1990 was 1200, the average 
high on that date for those 30 years is 1200/30 equals 40.  Similarly, if 
the sum of high temperatures on January 26 in that same area during that 
same period was 1170, the average high on January 26 is 39; and if the 
sum of high temperatures on January 27 in that same area during that same 
period was 1230, the average high on January 27 is 41.  However, a 
normalizing process smooths these differing average highs by a 
rather complex mathematical formula.  In this example, the "normal" high 
on all three dates would likely be 40.  It is these "normals" that are 
generally used by meteorologists when comparing current temperatures to 
the past, but some television weathermen have slipped into the bad habit 
of saying "15 degrees above average" when they really mean "15 degrees 
above normal."
While generally average and normal temperatures do not differ greatly, 
occasionally there are some rather startling differences.  For example, 
at Washington National Airport, the average high for the period 1961-1990 
on March 29 is 65 versus a 1961-1990 "normal" of 61.  However, on April 6 
at the same location, the situation is reversed:  The 1961-1990 average 
is only 59 versus a "normal" of 64.  Some of us wonder whether all such 
differences are merely statistical aberrations, or possibly reflect 
something real; e.g., regular variations in atmospheric circulation.

Hi, my name is José Torres Tores. I'm an agricultural engineer and now
I'm applying for an special project in the Balearic Islands.
I need any kind of information about simulating software existing for
simulate forestal fires. I know some experiences have been done in some
departmes of forestal sciences in the U.S., but don't know anything
else.
If you don't know this specific item, but know something in A.I.
applications (particullary cellular autommatas) I'd please very much
your help.
Please  post replys to this mail 
Thanks in advance.

Hi again,
Sorry for the delay. Here are the last images from hurricanes
GRETELLE and ILETTA (which has been baptized Friday afternoon).
I recall that the images are on the following anonymous FTP site:
 hostname : melusine.mpl.orstom.fr
 username : anonymous
 password : your e-mail address
directory : pub/incoming/gretelle
-rw-rw-r--   1 ftp      62         44138 Jan 25 22:31 P97012321.jpg
-rw-rw-r--   1 ftp      62         62113 Jan 25 22:31 P97012509.jpg
P97012321.jpg : B & W, Thursday night, NOAA-14 descending.
GRETELLE's eye is still very regular, its position is:
lat = 21.8 S
lon = 49.8 E
that means about 150 km off-shore of Mananjary.
P97012509.jpg : Color, two Saturday afternoon passes, NOAA-14 ascending
GRETELLE is almost "dead" after having crossed all the south part
of Madagascar, following a line from Manakara to Tulear. We can 
notice that while GRETELLE's eye is on the Mozambique Channel,
the corresponding cloud mass has stayed on land.
Hurricane ILETTA is on the north-east corner.

AMEN!!!! and we better all start helping eachother out to make sure the
financial burden is covered, or you will be paying for all this data,
and personally speaking, I will too. Of course I have a job in weather
and have access to data, but only for professional use. If I want it for
private personal use, I too have to pay. So lets remember that! Good
Post Sam!!!! :-) John

How high is the freezing level in the tropics? how far must the

Answers: a) way up there. b) a long way. Some smallish hail may
form in the tropics, but it won't make it back down as a solid.
