- Kids
- Parents
- Anyone who just wants to learn
- No previous qualifications necessary
- Those who question the standard attitudes
6My Background
- Grew up in Eastern Canada where temperatures
range from -60F to 120F - A climate that can kill you in 30 minutes in the
winter - A climate that fuels forest fires in the heat of
summer - A climate influenced by the Atlantic and prone to
getting hit by hurricanes and noreasters
7Learning the basics.
- Due to the climate, survival was taught at a very
early age - Got my first weather station when I was 11 years
old - Always been interested in the weather
- Career has been spent in media, and technical
documentation specifically in the defense industry
8The Scientific Method - Basic Science 101
- The 4 Steps of the Scientific Method
- 1. Observation description of a phenomenon or
group of phenomena. - 2. Formulation of an hypothesis to explain the
phenomena. - 3. Use of the hypothesis to predict the existence
of other phenomena. - 4. Performance of experimental tests of the
predictions.
9Basic Science 101 Part 2
- The scientific method works best in situations
where one can isolate the phenomenon of interest,
by eliminating or accounting for extraneous
factors, and where one can repeatedly test the
system under study after making limited,
controlled changes in it.
10Basic Science 101 Part 3
- There are circumstances when one cannot isolate
the phenomena. - This doesnt mean abandoning the Scientific
Method which many places of education do these
days. - This is about learning from the phenomena with a
wide open mind.
11Basic Science 101 Part 4
- Science is based on the correlation of facts, and
not of opinion based consensus. - A single data point does not imply a trend.
- The purpose of collecting data, is either to
support, or refute, a perception.
12The Scientific Method at Work
- Lets ask a basic question
- Is Global Warming happening on other planets
besides earth?

14Temperature Variations
- Figure shows eight records of local temperature
variability on multi-centennial scales throughout
the course of the Holocene, and an average of
these (thick dark line). The records are plotted
with respect to the mid 20th century average
temperatures, and the global average temperature
in 2004 is indicated. The inset plot compares the
most recent two millennia of the average to other
high resolution reconstructions of this period. - Source

15The Scientific Method at Work
- Lets ask another basic question
- Is there a connection between carbon dioxide
emissions and Global Warming?
16Temperature Variations vs CO2 Levels over Time
"Although CO2 can have a minor influence on
global temperature the effect is minimal and
short lived as this cycle sits on top of the much
larger water cycle, which is what truly controls
global temperatures. The water cycle is in turn
primarily influenced by natural celestial cycles
and trends."Dr. Tim Patterson, Professor of
Geology at Carleton University
17Temperature Variations vs CO2 Levels over Time
There is no statistical correlation between the
level of carbon dioxide in the atmosphere through
the last 500 million years and the temperature
record in this interval. In fact, one of the
highest levels of carbon dioxide concentration
occurred during a major ice age that occurred
about 450 million years ago. Carbon dioxide
concentrations at that time were about 15 times
higher than at present."
18Frequently Asked Questions - FAQ
- Is the earth really going to heat up due to mans
use of fossil fuels? - Im sorry Al Gore. But, mankind has little to do
with the warmup of planet Earth. - A Taste of the Truth
- http//www.heartland.org/Article.cfm?artid17977
- Mars Is Warming, NASA Scientists Report
- Data coincide with increasing solar
outputWritten By James M. TaylorPublished In
Environment NewsPublication Date November 1,
2005Publisher The Heartland Institute
19Meaning?
- One of two things
- Mans growth and development on Mars is creating
the same issues as on Earth. - Or,
- The sun has increased in output and all the
planets are getting the same conditions.
20Space Probes 20 Years Apart
- The hard cold facts that are available to the
public (not hidden by some conspiracy theory) are
that spacecraft that traveled by various planets
and moons in the last few years have seen a
unified increase in temperature from the
spacecraft that flew by the same locations 20
years ago. - All report a solar system temperature increase on
planets and moons across the board. - Therefore Global Warming is NOT manmade.
21A Lesson Learned - Question Orthodoxy
- All knowledge is based on tested theory and
hypothesis. - Knowledge has nothing to do with political
parties. - If you dont believe something is accurate, go
out and research the issue to find the real
answers. - Real facts dont lie always search for the
truth. - Question interpretations never settle on bad
science or politics. - Remember if there is a dollar to be made.that
will take precedence over truth by somebody
someplace in a capitalist society. - The truth will always persevere.
22Now Back to the Program.
- Planet Earth, our home planet,
- IS undergoing climate change!
- Which way warming up or cooling down or just
average? Irrelevant at this stage. - Basic Physics 101 heat from the sun is energy
- The expression used for calculating heat is
- Q cTm
- where
- Q Heat in Caloriesc heat capacity in the units
cal/gm-C, the heat capacity is defined as 1 for
water.T change of temperaturem mass in grams - No, we are not going to get into the calculations
of the physics of the atmosphere! - Lets simply assume that we have change taking
place which creates stronger storms a fact
found around the world and growing as each month
passes.
23Increased Energy
- When there is increased energy in the atmosphere,
you will have a change in the way the weather
develops. - The bottom line, is if we can not predict the
weather globally with a steady model, then it is
logical to state that we cant make long term
predictions of what will or what wont happen. - Predictions are only as good as the data and the
understanding of the data. - We have so much to learn a favorite quote I
like from a USM biology professor.

Storm Systems
26The Big Picture
- Advantages
- You see the whole planet in one shake.
- You can see storms a long ways away.
- You can make generalized statements.
- Easier for computers to make predictions.
- Disadvantages
- Real hard to tell what the weather is like
locally. - Real hard to understand micro-climates.
- Real hard to predict local weather events.
27The Big Picture Prediction
- What can we determine?
- Large Scale storm intensity predictions are good
for only a few hours changes too much not
enough data nor experience to be accurate a day
or two in advance.
28The Weather Scientists Favorite Tool - RADAR
29(No Transcript)
30Look Familiar?
31Large Scale Communications Systems Fail
Especially During Disasters (ie Katrina)
- All the large network communication systems
either failed or were destroyed. - Infrastructure that we relied on, was gone.
- Ham radio, CB radio, generators, and private
weather instrumentation systems survived.
32What have we learned so far?
- Question orthodoxy.
- Dont count on the government (insurance
companies?) to bail you out - Global Warming is NOT manmade.
- Is this bad? No, simply the facts of life!
- Will this happen again? We hope not only time
will tellthe odds are good that yes it will
happen again and it could be this year. - Have we learned anything?
33Predicting on a Small Scale
- Bad data is no data!
- Common sense rules
- Remember the weather rock?
- If the rock is white, its snowing
- If the rock is wet, its raining
- If the rock is moving, its windy
- If the rock is gone, then its been blown away!
- If a 500 mile wide storm is within 100 miles of
you the odds are real good you are going to get
hit by the storm!
34Listen, then Ask Questions
- Listening to an approaching storm or Mother
Nature in general, and you have facts then
interpretation of those facts is the learning
process. - You can make a difference for your own
satisfaction by setting up your own systems for
observing Mother Nature.
35Ways to Listen to Weather
- Ground Stations
- Temperature
- Relative Humidity
- Barometric Pressure
- Wind Speed
- Wind Direction
- Precipitation
- Weather Balloons
- Radar
- Sounding Rockets
36Ground Weather Stations
Ground weather stations rapidly collect wind
speed, wind direction, temperature, relative
humidity, and precipitation data and record it
for future analysis. Increasing numbers of
systems also post their information in real time
to the internet at such sites as
http//weatherunderground.com
37Weather Satellite Photographs
Photos transmitted from weather satellites can be
received using a conventional Hamtronics
receiver, satellite frequency antenna, WXSAT
analysis software
38Weather Faxes
The National Hurricane Center regularly
broadcasts via shortwave its WEFAX weather
service of forecasts maps translated by PC
software.
39Lightning Detection
Lightning can also be detected with conventional
antennas and receivers. Then, collected on a PC
for further analysis. Range up to 500 miles is
possible, with 250 miles normal. This makes an
effective early warning system for thunderstorms
and possibly tornados.
40Magnetic Effects
Thunderstorms and tornados produce magnetic
fields which get stronger as they approach. These
fields are easily monitored and captured via PC,
or basic chart recorders.
41New Orleans Tornado Signature
42New Orleans Tornado Life
433D Spectrum Analysis
Combining computing and sensors allows the
capability for advanced spectrum analysis. Shown
above is a 3D EMF analysis of a tornado based off
of a three second data capture. The circular
effects of the funnel are easily visible and
provide a snap shot of the electrical activity
around a tornado.
44Frequently asked Questions (FAQ)
- Is studying weather expensive to do?
- Only if you want it to be!
- You can do this on a shoestring budget
- You can do this with old items around the house
- You can do this with yard sale items you can find
45Private Weather Radar for Homes
- Couple of problems with this concept
- Way too expensive for 99 of the population
- Send out a signal that you control and you get
back a reply that only matches what you ask. - Would suffer the same coverage problem that the
major systems have.
46Developed Glenda Project
- I moved into the industrial side of weather
research while living in Seattle back in 1994,
and formed the Glenda Project with Dave Davis
http//glendaproject.org - Dave has a career background in rocketry and the
aerospace business - I have a heavy background in computers and
instrumentation - Solution deliver instrumentation via rockets to
study the weather..not a new idea in itself. - Our approachuse off the shelf components
47Glenda Project Typical Flight Profile
3 Deployment Phase
2 Boost Phase
1 Launch Phase
Note Propulsion is provided by reloadable/reusabl
e rocket motors giving the capability of
rapid turnaround between flights.
4 Recovery Phase
48Rocketry Fundamentals
- Once a rocket goes above a mile you simply cant
see it. - No point launching unless you have a chance of
finding the rocket. - Therefore, no point launching unless you have
telemetry. - Could one do micro-prospecting from a rocket?
- Could we learn more about the weather by
launching instrumentation payloads into the storm
fronts?
49Motivation for Products
- Need to define research goals and develop
products to pay for further research. - Basic high power rocketry, gets expensive
quickly. - High Power Rocketry requires licenses for the
purchase of motors. - Comprehensive government requirements for control
and storage of motors and fuels (Homeland
Security Regulations have increased controls to
the extreme) - How often do you launch, and when needed
defining. - FAA launch requirements are different than the
hobby (no launch into clouds) rocket regulations.
50Defining Research Development
- The Goals of the Glenda Project
- The primary mission of the Glenda Project is to
provide the capability to rapidly gather
previously inaccessible localized microclimate
data from altitudes ranging from ground level to
40,000 feet and to return this data for immediate
use. - The Glenda Project is a reusable sounding rocket
delivery system research and development program
designed to place instrument packages into areas
previously considered to be to hazardous or
inaccessible using traditional platforms such as
balloons, aircraft, helicopters, kites, etc. - The Glenda Project rockets have the capability to
collect temperature, humidity, barometric
pressure, wind speed and other types of
environmental data from ground level to 40,000
feet. - The rockets are designed to be launched into
thunderstorms, tornados, and other volatile
weather environments and to return intact with
the collected data.
51Back to the Program.
- Okay how do you know when to launch?
- Storm chasers go in search of storms for
pictures, radar analysis, and thrills. - Storm chasers have lots of open room on the
plains in Washington state you have mountain
ranges, coulees and empty desert and not
necessarily in that order. - In Mississippi you can do research on storms
however tornado chasing is dangerous due to lack
of evacuation routes.
52What Has Glenda Learned?
- Celebrating 10 Years of Research and Development
1997 2007 - Glenda has three methods of collecting data
- Active Flight Data Collection Systems -
Transmitters - Passive Flight Data Collection Systems
Dataloggers - Ground Stations
53Identifying Phenomena
- Bottom Line - Identifying the approaching weather
phenomena to determine whether to go or no go
chase or hide. - Weather conditions happen at altitude before
being perceived by ground stations. - Only way one can do that is with long range, or
satellite sensors. - Weather services do this with radar.
54In Conclusion
- The Scientific Method generates more reliable
data, than political consensus. - Localized systems tend to be more robust in
disasters. - There are multiple ways to listen to the weather.
