2. What you are about to see is a small selection of sample lesson slides from a selection of the eight lessons on the ‘Meteorology ... Simply for Yachties’ CD.
On this demonstration disc, the slides under each lesson title do not necessarily follow any specific order and there are many other linking slide animations that are not show that normally provide the lesson with the ‘flow’ that is not immediately apparent in this demonstration. Naturally, the full version has all the links and ‘flow’ necessary to understand and absorb the topic in question. 
At each stage during viewing, allow the animation to run for a couple of seconds before using the mouse button or scroll wheel to move on. On the full version CD, each lesson has a self testing interactive quiz at the end of the lesson. An example is also given on this disc.
The full version of the ‘Meteorology .... Simply for Yachties’ CD is made up of well over 370 animated lesson slides covering all 8 lesson topics. Let’s now have a look at some of the lesson slides

5. THE STANDARD ATMOSPHERE
FOR COMPARISON PURPOSES, THE TROPOSHERE (ATMOSPHERE) IS GIVEN A SET SERIES OF PARAMETERS
NORTH POLE
IT IS ASSUMED THAT THE SURFACE TEMPERATURE IS +15°C AND THAT TEMPERATURE DECREASES WITH HEIGHT BY APPROX 2°C PER 1000 FT.
AT THE TROPOPAUSE, (AVERAGE HEIGHT 36,090 FT), IT REMAINS CONSTANT AT –56•5°C, DESPITE ANY FURTHER INCREASE IN DISTANCE FROM THE EARTH
AT THE EARTHS SURFACE, IT IS ASSUMED THAT THE STANDARD PRESSURE IS 1013•25 HECTOR PASCALS (hPa) AND PRESSURE REDUCES WITH HEIGHT BY ROUGHLY ONE hPa PER 30 FT IN THE LOWER LEVELS

11. FORCES CONTROLLING WIND
ONCE THE GEOSTROPHIC WIND BEGINS TO FLOW, THE GEOSTROPHIC FORCE ALWAYS ACTS AT RIGHT ANGLES TO IT AND IS PROPORTIONAL TO ITS SPEED
THE PRESSURE GRADIENT FORCE STILL ACTS ACROSS THE ISOBARS FROM HIGH TO LOW PRESSURE
IN THE NORTHERN HEMISPHERE, THE RESULTANT GEOSTROPHIC WIND IS PROGRESSIVELY DEFLECTED RIGHT, TOWARDS THE ISOBARS
THIS PROCESS CONTINUES UNTIL THE PRESSURE GRADIENT FORCE AND GEOSTROPHIC FORCE OPPOSE EACH OTHER

13. OROGRAPHIC (AIR FORCED UP OVER HILLS) SOLAR HEATING AND CONDUCTION
TRIGGER ACTION
ANY METHOD THAT ASSISTS AND LIFTS AIR ABOVE THE SURFACE CAN PROVIDE THIS ‘TRIGGER’
THERE ARE THREE MAIN ‘TRIGGERS’ THAT START AIR MOVING VERTICALLY UPWARDS
OROGRAPHIC (AIR FORCED UP OVER HILLS)
SOLAR HEATING AND CONDUCTION
FRONTAL LIFTING
ANY ONE OR A COMBINATION OF THESE MAY START THE BUILDING PHASE OF A THUNDERSTORM

14. DO YOU REMEMBER THIS GRAPH OF ABSOLUTE INSTABILITY?
TROPOPAUSE

- TEMPERATURE +
BOTH SATURATED AND DRY AIR IS ALWAYS WARMER THAN THE ENVIRONMENT AT ANY LEVEL
ENVIRONMENTAL LAPSE RATE
‘LIFTED’ AIR WILL CONTINUE TO RISE UNTIL IT REACHES THE TROPOPAUSE
THIS IS TOTAL AND ABSOLUTE INSTABILITY AND IS THE ‘ENGINE ROOM’ FOR DEVELOPING MAJOR THUNDERSTORMS
