In this paper, the turbulent kinetic energy (TKE) value was estimated and calculated as an
important indicator of turbulence. The directional distribution of the TKE value was observed for
different directions of the location. The relationship between variables of different turbulent
characteristics (e.g. Turbulence for horizontal wind velocity, Horizontal Momentum Flux MF, air
temperature and density) and kinetic energy induced by horizontal wind turbulence, has been tested. And
finding a mathematical formula describing this relationship.
The data recording process in the city of Baghdad continued for a whole month from 1/7/2016 to
31/7/2016 using fast-response wind velocity measuring instruments. The records included the three
components of wind velocity (u, v, w) and temperature and sound speed, recorded observations of the
times 3: 00.6: 00.9: 00.12: According to local time Baghdad. Also, air pressure was recorded on hourly
basis for the same day through the automatic weather station (Davis vantage pro 2).
