Ulence dominated starting from z1 = 100 m and non-monotonically changed with altitude, with improve in time, z1 improved, the turbulent layer thickness decreased toAtmosphere 2021, 12,six of205 m, but max reached 15,000 by the end of this period. In fact, a very thin turbulent layer was observed close to the maximum sensing altitude that had an extremely high turbulent kinetic energy and therefore is quite harmful for the UAVs and high-rise developing and Atmosphere 2021, 12, x FOR PEER Evaluation promising for wind power applications. By midnight, from 22:00 till 23:00, the contribution six of 11 with the kinetic power decreased. The turbulent layer thickness decreased with rising time with simultaneous reduce of max to 300 and lower of z1 .Figure two.

Diurnal hourly dynamics of the ratio with the turbulent to the mean kinetic wind power elements.Thus, beginning from midnight for the duration of evening and early morning hours, the lower boundary of your layer of enhanced turbulence changed from 400 m at 0:00 to 150 m at 07:00 with nonmonotonic variations of max from 800 at 05:00 to 40 at 08:00. Inside the morning (from 09:00 till 11:00), z1 slightly improved, and max decreased from 300 to 150. The circumstance changed at noon from 12:00 until 13:00. Throughout this period, theAtmosphere 2021, 12,7 ofPractically at any time, except about midnight (from 23:00 till 00:00), the contribution of the mean kinetic energy dominated at altitudes beneath one hundred m; above this altitude, the relative contribution of the turbulent or imply kinetic power depended around the time of the day plus the sounding altitude. It needs to be noted that at low max Cirazoline Biological Activity values (for example, at 08:00, 14:00, 18:00, and 23:00), the thickness from the layer of enhanced turbulence, as a rule, was huge (from z1 = 5000 m to 200 m). In this case, the turbulent kinetic flux power density was not so significant, but virtually within the whole altitude variety, the turbulent energy contribution prevailed. However, at high max values (as an example, at 05:00, 12:00, 17:00, and 21:00), the thickness of the layer of enhanced turbulence, as a rule, was little (105 m). This thin turbulent air layer transfers a sizable volume of turbulent kinetic power and is dangerous for UAVs and high-rise buildings because of the unpredictable effect on them. Thus, determined by the outcomes obtained, we are able to conclude that the air kinetic energy inside the reduced 100 m layer weakly depends on the altitude z and increases with further raise in z. The diurnal behavior of radiative heating in the underlying surface causes the presence of minima and maxima of the wind kinetic power whose occurrence depends upon the meteorological conditions of observations. The dependences of the ratio in the turbulent to the mean kinetic wind energy elements (z) = ETKE (z)/EMKE (z) in linear coordinates visually characterize its behavior at altitudes z above 100 m and have allowed us to recognize the layers of enhanced turbulence exactly where the turbulent and mean kinetic wind power elements yield comparable contributions. At lower altitudes, exactly where the contribution of the turbulent kinetic wind power element is tiny and the ratio (z) lies in the range 0.010, the altitude dependence shown in Figure 3 on semi-logarithmic scale is much more informative. In distinct, four layers are clearly distinguished by the character on the altitude dependence with the ra.
