Splet07. apr. 2024 · Through utilising a high-resolution model which explicitly calculates turbulent dynamics, this paper showcases the impact of BC on PBL dynamics both within and above the PBL. These results show that BC within the PBL increases maximum PBL height by 0.4 % but that the same loading of BC above the PBL can suppress PBL height … Splet05. avg. 2013 · The planetary boundary layer (PBL) can be defined as “that part of the troposphere that is directly influenced by the presence of the earth’s surface…” (Stull …

As the bottom layer of the troposphere, the planetary boundary layer (PBL) is directly affected by Earth's surface. Turbulent mixing in the PBL dominates the exchange of energy, mass, and momentum between the surface and the atmosphere, and strongly influences the tropospheric temperature, humidity, and wind …
Splet70 PBL height. Furthermore, they found that a BC layer close to the PBL top and internal mixing of BC with scattering aerosols (sulphate, nitrate, ammonium) signicantly enhanced the dome effect of BC, leading to a potential reduction in PBL height of 15 %. Splet01. mar. 2024 · It is important to accurately estimate the PBL height (PBLH)—which is strongly influenced by physical factors, including evaporation, sensible heat flux, wind, …
