Dispersion of pollutants in convective low wind: a case study of Delhi

Goyal, P; Rama Krishna, T V B P S (2002)

The transport and dispersion of pollutants becomes weak under low wind conditions resulting in large ground level concentrations (g.l.c.'s). Largest mean g.l.c.'s due to elevated sources are typically found under daytime ...

A line source model for Delhi

Goyal, P; Rama Krishna, T V B P S (1999)

A line source model, developed in Indian Institute of Technology (IIT) Delhi, India, namely IIT line source (IITLS) model, is proposed to describe the downwind dispersion of pollutants near roadways along with a brief ...

Comparative study of line source models for estimating lead levels due to vehicular traffic in Delhi

Rama Krishna, T V B P S (1995)

Studies concerning the concentration of lead (Pb)in Delhi due to vehicular traffic are being conducted under sponsorship of Ministry of Environment and Forests, Government of india. The comparison of results of two line ...

On the bulk Richardson number and flux–profile relations in an atmospheric surface layer under weak wind stable conditions

Sharan, Maithili; Rama Krishna, T V B P S; Aditi (2003)

For describing the surface fluxes in the atmospheric dispersion models, the commonly used linear universal similarity functions m and h for nondimensional wind and temperature profiles (J. Atmos. Sci. 28 (1971) 181; ...
