This research shows that if three planets are on a straight line the beginning of a storm is triggered. This makes better weather forecasts and earlier warnings for dangerous situations possible. It also gives more understanding of the influence of planets. Review of about fifty big storms in history show that if three planets form a nearly exact straight line, here named a planet line, a severe storm begins. If the line is less exact, just a moderate storm starts, but if a next line follows soon after, a big storm develops. Combinations of more planet lines make the storm more severe. You can see the wind speed going up and down with the coming and going of the planet lines. Of course the effect is not restricted to the Earth. The same is shown to occur with Solar storms. The Analysis, with comparisons of storms, shows the most amazing and convincing results.
