TOWARDS A RATIONAL CLIMATE MODEL
I have been particularly impressed by the graphical description of the basic properties of the climate by the online notes published by Lyndon State College Atmospheric Sciences | 1001 College Road | Lyndonville, Vermont 05851 at
I give examples from Chapter 3 at
Let us start with the Sun.
There needs to be three separate sets of models, each of which can have a rational average. They are
- 6am to noon, where sun increases in a regular fashion and radiation tries to increase
- Noon to 6pm where sun declines in a regular fashion and radiation tries to decline
- 6pm to 6am where there is no sun and all radiation declines.
There would have to be a range of models to handle latitude and seasonal changes.
Earth Temperature lags behind the Sun, but can be handled by only two basic models,
- 6am to 3-5 pm with an increase;
- 3-5pm to 6 am with a fall.
However, The second graph plots energy. which is proportional to the fourth power of absolute temperature so the two averages will correspond to higher temperatures than the averages in the first curve.
Then the temperature of the atmosphere is determined by convection, with a difference between day and night
All of these models need sets of modifications for latitude and seasons.
The pervasive influence of water vapour, clouds, rain and snow, and aerosols are additional complications.
A rational climate model should be based on the above considerations, but at present we lack the data or the computation power to provide an effective forecasting system which can goes further than that which exists at present. However, the gross oversimplification of the current climate models means that they can never be successful.
The college also gives notes on the greenhouse theory, which fail to address its defects.
I might just mention that although I am not a meteorologist I once ran a weather station on the roof of my secondary school from 1937-1939. We were all terribly keen and took it in turns to read the instruments every day, even during weekends and school holidays. Each day there was a weather forecast on the bulletin board.
The temperature fell during school holidays because the boilers were shut down.
