This also strengthens the idea that the ultimate driving force of plate tectonics is a large-scale circulation of the mantle.
The recent research using that model suggests that the huge increase in pollution around the North Atlantic basin in the mid-20th century cooled the surface enough to change the large-scale circulation of the atmosphere, suppressing storms.
The slope in sea level across the Gulf Stream has been measured by satellite radar altimeter to be one metre over a horizontal distance of 100 km (62 miles), which is sufficient to cause a surface geostrophic current of one metre per second at 43° N. The large-scale circulation of the Gulf Stream system is, however, only one aspect of a far more complex and richer structure of circulation.
AGW forcing plays an important role in large-scale circulation of the middle and upper atmosphere (Fritts and Alexander 2003; Geller et al. 2013).
From the large-scale circulation of the atmosphere one expects downwelling in the winter at high latitudes, causing enhanced atomic oxygen and enhanced airglow while the opposite is expected in summer.
The main components of large-scale circulation of the eastern tropical Pacific were identified in the mid 20th century, but the details of the circulation at length scales of 102 km or less, the mesoscale field, are less well known particularly during summer.
An abrupt change in hydrography and large-scale circulation of the deep waters of the Eastern Mediterranean resulted from a unique, high-volume influx of dense waters from the Aegean Sea during the 1990s.
However, in terms of predicting whether a hurricane will hit NOLA or Mobile AL, that is inherently uncertain more than few days out (predictability depending on the large scale circulation system and the strength of the storm).
Boundary layer turbulence plays an important role in driving large-scale circulations of the atmosphere as it transports heat upward from the Earth's surface in the form of sensible and latent heats, which are converted from incoming solar energy at the surface (Trenberth et al. [2009]).
This data set also reveals the utility of BC MMR as a tracer of large-scale circulation in the atmosphere.
Given the spin-up of the large-scale circulation in both the lower and the middle troposphere loosely coupled by enhanced convection, what determines the onset of the pressure deepening and subsequent intensification? Figure 5 presents the time evolution of the inner core of the simulated storm.
