However, ignoring
the varying time lag the two generally will track each other because they are really the same thing.
Not exact matches
The researchers studied growth rates and
lag times in both lab strains and wild yeast by
varying the amount of its prime carbon food source, glucose.
The jet
lag also plays a big part at this stage in the year, when you're flying from continent to continent with
varying time zones.
What you've said is encapulated in my short statement that there is uncertainty in the
lag / lead precisely because of uncertainty in the trapping
time, which does (as you say)
vary with conditions (notably, temperature and snow accumulation rate).
With such a system the observed
lag times will
vary with the frequency of the applied signal.
In effect they simply continue the distribution of the initial (solar induced) warming or cooling state around the globe and of course there are
varying degrees of
lag so that from
time to
time the other lesser oceanic oscillations can operate contrary to the primary Pacific oscillations until the
lag is worked through.
I agree the
lag does not appear to be constant, and does
vary, and may not explain everything, however, someone earlier dismissed the
lag between temperature and CO2 as irrelevant, so I made some simple calculations, and surprised myself, in that (possibly) co-incidentally the
lag of roughly 800 years + / - 200 (my own estimate), matched the
time between the MWP and the start of Industrialisation, where CO2 levels are said to start rising, of course it's a very rough estimate.
The northward migration of warm waters from the South Atlantic to the North Atlantic also appears to be present in the following animation of the correlation of NINO3.4 SST anomalies with Atlantic SST anomalies at
time lags that
vary from 0 to 12 months, Animation 2.
Data from 1,093 youth / parent pairs were analyzed from the Youth Assets Study using a Generalized Estimating Equation approach; family and neighborhood assets and risks were analyzed as
time varying and
lagged.
