The glacial interglacial transition was characterized by rising lake levels across much of the continent, but transgressions show marked reversals that appear related to large-scale dynamics such as changes in the thermohaline circulation and fluctuations in sea-surface temperatures.

The potential slow release of tracer vitamin D from body stores and the consequent further and additional hepatic production of labelled 25(OH D into the circulation would cause fluctuations in labelled 25(OH D concentration and may distort the 25(OH D half-life.
Despite major fluctuations in serotype circulation, DENV-2 circulated predominantly for 10 years, alternating with DENV-1 through 2 periods of resurgence during the 1990s and cocirculation of DENV-4.
Varying reservoir conditions and fluctuation in circulation flow rates cause sudden variations in the pressure conditions along the well.
The study found that the increase in the Northeast was caused by a 30percentt slowdown in a major ocean current system known as the Atlantic meridional overturning circulation (AMOC) and a fluctuation in atmospheric pressure at sea level.
Others hypothesise that placental vascular anastomoses between the monozygotic co-twins' circulations may lead to fluctuations in blood flow during fetal heart development, causing CHD. 25 26 If the aetiology of CHD in twins is predominantly haemodynamic as opposed to genetic, this may explain why chromosomal anomalies were less common in twins with CHD compared with singletons.
That is, CO2 drives a relatively steady warming (on these time scales), but the actual rate of warming experienced fluctuates about that 'steady' rate because of natural fluctuations in ocean circulation.
The occurrence of articulated seafloor morphology over continental shelf-upper slope environments, may result in a significant change in the patterns and intensity of basin-scale thermohaline circulation during eustatic sea-level fluctuations.
Combined with quantitative information about vector-reservoir contact, mosquito population fluctuations, and virus circulation intensities, EVEV transmission dynamics can be elucidated.
