Expected values of fluctuations were also highest at this region, as shown in Figure 3.
The reduction to sea level means that the normal range of fluctuations in pressure is the same for everyone.
The magnitude of fluctuations in output and hours worked are nearly equal.
The argument so far has glossed over the question of fluctuations.
But this information is not enough to estimate the probability of fluctuation.
They say that nature is actually in a continuing state of disturbance and fluctuation.
There is no special force of nature involved in the generation of such fluctuations.
But "it is still nothing like the kind of fluctuations that used to occur prior to 1984 on a regular basis."
It is not known how long the spot will last, or whether the change is a result of normal fluctuations.
To explain causes of such fluctuations may appear rather difficult given these irregularities.
