Sentences with phrase «shows sine waves»

The drawing shows sine waves that resemble waves on the surface of water being reflected from two surfaces of a film of varying width, but that depiction of the wave nature of light is only a crude analogy.

He used the Lomb - Scargle routine in IDL to determine the most significant periodicity in the data (= 3.2 days), and then used this as input into a least - squares sine wave fit to produce the fitted curve shown.

However, a search for some reconsiliation between the global temperature record and possible BNO (R) forcings by altering its strength and / or timing (be it in the form of square wave or sine wave or any other wave) may show nothing other than the existence of many competing and controversial alternatives.

The energy requirements for BNO (R) are shown to be quite large — an oscillating radative forcing of 1.15 Wm ^ -2 peak - to - peak if of square - wave form, 1.8 Wm ^ -2 if of sine - wave form.

It certainly would happen if you put all five sine waves into independent play, as I showed after unchecking the «keep all unconstrained parameters nonnegative» box that Rossander left checked: it would always give an R2 of 1.00000 no matter what you changed HadCRUT3 to, even if you changed it to something that looked nothing like a sawtooth.

Don't forget cycles in autocorrelation do not necessarily result from such nice sine wave looking cycles in the data, but do show repetitions of pattern.

By applying the same technique to a sine - wave (which the audience had agreed exhibits a zero trend), it is possible to show either a rapidly - accelerating uptrend or a rapidly - plummeting downtrend, depending on the choice of endpoints for the trend - lines on the data.

Now, if you want to establish that hypothesis, or if you think that is true, how does showing that the climate can be simulated by a couple of sine waves plus a trend show anything at all?

Using just 4 sine waves in a periodic but stationary function will give a pretty good fit to the modern day temperature decomposition you showed without invoking any AGW at all.

Secondly the same formula has been shown to produce an upward trend in a sine wave which is neutral by nature at all points.
