Natural Variation. Natural variation includes internal and external variability influences such as the solar Schwabe cycle, oceanic cycles, seasonal influences based on changes caused by the interaction of the various natural oscillations in the climate system.
Answer by solver91311(22529) (Show Source): You can put this solution on YOUR website! It means raised to the power of. So if you see x^2, then it means x raised to the power of 2, which is to say x squared or . If you only see x^, then the writer is incorrectly using the symbol, probably to mean x^2, i.e. .
VA = Watts (DC current). In AC if the volts and amps are in phase (for example a resistive load) then the equation is also. VA=Watts (resistive load) where V is the RMS voltage and A the RMS amperage. In AC, the volts and amps are not always in phase (meaning that the peak of the voltage curve is does not happen at the peak of the current curve). Think of pushing a swing. The greatest force is applied when the swing stops at the peak, but the greatest velocity is at the bottom of the arc.
