Mike Wallace Historian, co-author, "Gotham: A History of New York City to 1898" From a planetary perspective, New York has for centuries been a crucial node in the global circulation of capital, labor, information, commodities and cultures.
This local 40 50-day oscillation is later understood as associated with an equatorial planetary-scale circulation system coupled with large-scale convection that moves eastward slowly with a speed of about 5 m/s in the eastern hemisphere (Madden and Julian 1971; Nakazawa 1988).
This results in the formation of planetary wind circulations that experience a strong Coriolis deflection and thus can be considered 'quasi-geostrophic'.
The model is shown to produce robust large-scale characteristics of the observed MJO, including the coupled Kelvin Rossby wave structure, slow eastward propagation (~5 m/s) over warm pool, the planetary (zonal) scale circulation, the BL low-pressure and moisture convergence preceding major convection, and amplification/decay over warm/cold sea surface temperature (SST) regions.
From a dynamical standpoint, we may define MJO as a tropical, planetary-scale, unstable circulation system (coupled with a multiscale convective complex) that moves eastward slowly (~5 m/s over the war pool ocean) with a rearward-tilted vertical motion and a coupled Kelvin Rossby wave structure.
He contented himself with showing that the planetary theories then in circulation did not agree with the phenomena.
Depositions of OGW momentum and heat have primary effects directly modifying general circulation and planetary waves and secondary effects of influence of modified mean flow on the wave propagation conditions.
Plate tectonics is a convection style that dominates the material circulation between a planetary surface and its interior.
Since there are no remarkable zonal phase structures in the SABER temperature data during this period (not shown here), it is difficult to infer that this local poleward wind disturbance is due to any modulation of planetary waves or enhanced meridional circulation.
It includes large-scale ocean thermohaline circulations, biogeochemical processes, planetary atmospheres, educational use, debugging, and parameter tuning, with focused time scales from decades to several million years (Claussen [2005]).
