Study of Turbulence Kinetic Energy Budget over Jodhpur, India
Journal Title: Journal of Environmental and Social Sciences - Year 2015, Vol 2, Issue 1
Abstract
Atmospheric turbulence plays an important role to understand the behavior of pollutants in lower atmosphere which has a large impact on surrounding environment. In the present paper, the one-dimensional Turbulent Kinetic Energy (TKE) budget in a steady and homogeneous condition is studied. The data from a 30m micrometeorological tower during Indian Summer Monsoon (ISM) of the year 1990 over a station Jodhpur (26.3° N, 73°E), which represents a dry convective station and situated at the eastern part of ISM trough over the Indian subcontinent, is used. The tower data is of Fast and Slow Response data. The Fast Response Data (FRD) sampled at (8 Hz) is collected at 4 m and 15 m levels whereas the Slow Response Data (SRD) sampled at (~1 Hz) is collected at six levels viz. 1, 2, 4, 8, 15 and 30m. The analysis of each component of TKE budget is done for active and non-active phases of monsoon at 4m and 15m levels. All terms of TKE budget show considerable variations at 4m levels. At 15m, the variations of term are not remarkable. It has been found that at both of the levels shear production term dominates over all other terms during active phase of monsoon while buoyancy dominates during day time at 4m level in both of phases. The buoyancy and shear terms influence mixing and transport of pollutants in the lower part of the atmosphere in day time during active and non active phases of ISM. TKE budget over Jodhpur, Kharagpur and Varanasi shows that buoyancy is not a major contributing factor during the summer monsoon season while major contributing factor is shear production.
