Wow, i actually cant understand how stupid people are. Do you have any knowledge at all about how hurricanes are formed, or just how clouds are formed?
For one this Africa bit, the Very thin cloud cover created can be from power stations releasing aerosol particles into the air, this in other words is a nucleus for water vapour to condense on. This is very stable cloud and cannot be turned into any storm, its just cloud cover. Or more likely it could be cold or warm fronts. As the warm air rises it expands due to the decreased pressure in the upper atmosphere, it cools and condenses creating cloud.
What on earth are you trying to say with "frequency generated gravity wave"!! A gravitational wave is a ripple in the curvature of spacetime and is so small that a wave moves somewhat less than the distance of an atom, and these waves are generated by colliding black holes, thousands of times the mass of the sun. How are we supposed create a gravitational wave large enough to affect clouds on earth? And that is not how a gravitational wave propagates. First of all a gravitational wave propagates in a ripple effect in 3 dimensions and secondly it travels at the speed of light.

Finally, IF they created that cloud in Africa, how does that create a hurricane? cloud cover does NOTHING to create hurricanes. Literally nothing, you need thunderstorms to create a hurricane, a thunderstorm is created by the collision of a cold front into a warm moist parcel of air, lifting the warm air and condensing the water vapour. If the cloud is already there or not, it makes no difference what so ever. For Atlantic storms Africa supplies only the heat needed to start the storm. The Moister comes from the massive ocean next to it.

Please before next time you post, open a fucking book. One that's scientific please.
