Reading 1 Federalism What is federalism? Federalism is a system of government in which power is distributed or diffused between a central government and smaller political units. In the United States, there are three basic levels of government: federal, state and local.
The large majority of the tornadoes in the northern hemisphere spin counterclockwise (cyclonically), but about 1 in 100 tornadoes spin clockwise. Actually, it has little to do with being in the northern hemisphere, as tornadoes do not last long enough for the effects of Coriolis to impact it.
Although understanding Coriolis's weak influence over the direction of a tornado's spin seems feasible, fully grasping how tornadoes function may not be. And predicting exactly when and where tornadoes will occur-and which way they will spin-seems even less so. Uncertainty may be the only certainty of weather.
