RE: Chapter IVa: Climate issues, part 1

Everything seek out stability. Both thermal convection and air molecules seek out patterns that means domination of a weather system. The most stable, less energy consuming and lasting (compact) pattern is a hexagon, like in (bee) honey cubes. Then other polygon shapes. If a pattern can't be hexagon in a system, then it is preferred to be quasi-hexagon (instable) before breaking up in both regular turbulance and irregular turbulence.

A first weather system with a seemingly stable situation might turn unstable, but more energy efficient (path of less resistance) if a second weather system with higher (turbulent) energy clash into the first one. The second weather system prefer to "attack" where the first weather system is most vulnerable - at areas with steady flow (that beeing (quasi)linear or regular nonlinear) and put some of the energy from that into itself by little energy transitions as possible. Then use more energy to take over irregular areas with nonlinear, unsteady (turbulent) flows of air molecules.

So the new combined weather system will be much the same (or in "upgraded" shape) like the second one and devastate more or less the surroundings if there is a much of the monoculture that is man made in the surroundings.

Both open fields with little or low vegatations and cities with much asphalt roads and buildings with smoth walls will "encourage" the weather systems there to gain or build up energy with some help from outside weather systems.

This probably was the reason that a big hurricane took weather forecasters by surprice when it struck southern Britain exactly 21 years today (at 15th october 1987). And this probably explain erratic behavior of hurricanes at the coast of southern USA - the hurricanes origin at a western bay of Africa, and the build up of energy there is perhaps caused by more monoculture instead of great variations of vegetations, and by more buildings that block energy travel inward land.

A lot of different air molecules (aerosols) from vegetations and a lot of small animals or insects (like butterflies) all participate to break up weather systems so they won't become quasi-regular and powerful to create swirling storms or hurricanes. More varied vegetations and less flat areas counter the effect of energy building up in the weather systems. This seems to be difficult for scientists and politicians to understand.
