The purpose of this study is to utilize the satellite procured data to identify the best wind potential locations in KPK, Pakistan by analyzing the monthly and annual averaged wind speeds along with the resultant wind speed and wind direction for the districts (Dir, Chitral, Buner, Mansehra, Peshawar and DIK) at heights of 10m (1983-1993) and 50m, 100m, 150m and 300m (1983-2005).
On the lee side of the ridge, eddies may be formed by strong winds; in the lower parts of these eddies, the resultant wind direction becomes opposite to the main wind flow.
In order to determine at the relationship between air quality and wind patterns, the levels of pollution and the resultant wind directions were compared.
Table 1 and Figure 5 represent the average monthly resultant wind direction in degrees.
Luckily, one of the monitoring stations recorded both the resultant wind direction and PM10 levels.
A comprehensive set of highway cross-sections and pertinent physical relationships were examined for resultant wind flows, turbulence, concentration fields, and visual tracer paths.
Figure 10 plots the shape coefficient and resultant wind forces of the platform over the water in 7 wind directions calculated by using the UDF function.
According to China Classification Society common rule and [19], the resultant wind forces are related to the windward area of the structural member, the wind speed, and pressure.
