Assessment of Turbulence Intensity in Different Spots of Lightning Flash Propagation
نویسندگان
چکیده
The updraft speed is correlated to the total lightning flashes a storm produces. Shear along gradients one of mechanisms responsible for production turbulence kinetic energy (TKE). Thus, radar-estimated eddy dissipation rate (EDR) overlapped with Lightning Mapping Array (LMA) data used evaluate storm's kinematic and electrical relationship. majority sampled shows higher intensities close initiation regions. As distance from increases propagation path, there gradient less turbulent We identified small-sized medium-sized initiated at lower altitudes in regions smaller EDR values consistent unmixed flow within inner part updrafts. Furthermore, were concentration small upper portion cloud high due their associated small-scale variability.

the role of application of dynamic assessment approach in improvement of iranian efl writing performance at different language proficiency levels
the present study sought to investigate the role of dynamic assessment (da) in improvement of iranian efl writing performance at different language proficiency levels. to this end, after conducting the quick placement test, 60 iranian efl learners were assigned to two groups with different language proficiency levels. in both groups each participant wrote two compositions, one before and one af...
assessment of the efficiency of s.p.g.c refineries using network dea
data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...
Investigation of Air Turbulence Intensity Effect on the Flame Structure in Different Flame Holder Geometry
In this paper, the effect of air turbulence intensity on the flame structure in various radii and lengths of a flame holder numerically studied. Finite volume method is used to solve the governing equations. The obtained numerical results using realizable k-ε and β-PDF models show a good agreement with the experimental data. The results show that flame holder with greater lengths yield shorter ...
