This change includes
all normal seasonal variations forest fires, dead fall, harvesting, anthropogenic influences... (Albeit with a rising trendline.)
Economists like Mr. Shapiro cautioned that the numbers, which are adjusted
for normal seasonal variations, are volatile from month to month and are still subject to revision.
Most economists expected a decline after auto production soared in July, largely because there were fewer plant shutdowns in July made output look stronger after the government adjusted the figure for normal seasonal variations
3) The global albedo changes necessary to produce observed climate variability and the changes in solar energy input to the oceans can be explained by the latitudinal shifts (beyond
normal seasonal variation) of all the air circulation systems and in particular the net latitudinal positions of the three main cloud bands namely the two generated by the mid latitude jet streams plus the Inter Tropical Convergence Zone (ITCZ).
The SAAR corrects for
normal seasonal variations and projects annual shipments based on the current monthly total.
