Tropical Cyclone Boundary Layer Shocks
This paper presents numerical solutions and idealized analytical solutions of axisymmetric, f -plane models of the tropical cyclone boundary layer. In the numerical model, the boundary layer radial and tangential flow is forced by a specified pressure field, which can also be interpreted as a specified gradient balanced tangential wind field vgr(r) or vorticity field ζgr(r). When the specified ...
متن کاملThe Vertical Structure of the Eddy Diffusivity and the 1 Equilibration of the Extra - Tropical Atmosphere
4 Observations suggest that the timeand zonal-mean state of the extra-tropical atmosphere 5 adjusts itself such that the so-called “criticality parameter” (which relates the vertical strat6 ification to the horizontal temperature gradient) is close to one. Schneider has argued that 7 the criticality parameter is kept near one by a constraint on the zonal momentum budget in 8 primitive equations...
متن کاملsimulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water
abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
Stable Boundary Layer Mixing in a Vertical Diffusion Scheme
The YSU PBL scheme is a revised vertical diffusion package with a nonlocal turbulent mixing coefficient in the planetary boundary layer (PBL). Based on the study of Noh et al (2004, BLM) and accumulated results of the behavior of the Hong and Pan algorithm, a revised vertical diffusion algorithm that is suitable for weather forecasting and climate prediction models is developed. The major ingre...
متن کاملThe Effect of the Ocean Eddy on Tropical Cyclone Intensity
It has been widely recognized that the ocean supplies surface heat fluxes and therefore energy to tropical cyclones (TCs). The TC can induce the sea surface temperature (SST) cooling (Price 1981) associated with both the entrainment/mixing and upwelling processes. In turn, the SST cooling near the storm core exerts influence on the TC intensity. This negative feedback to the TC intensity is cle...
