After it takes the measurement, the app automatically creates an onsite report, which summarizes wind direction
, average speed and peak gust.
The above-mentioned coefficients and parameters are provided in Table II and Table III only for the prevailing wind direction

In addition to wind direction
, wind magnitude is generally required.
We can see that when the wind direction
is aligned along the direction of the valleys ([alpha] = 260[degrees]) the flow is channelled through these long valleys (Fig.
These areas are typically found in lower elevations, which reduce the effects of the front on wind direction
With these tools they were able to draw conclusions by considering the dual effect of cloud cover and wind direction
There has been a shift in the wind direction
to northwesterly on Thursday evening, which would make days colder yet again.
However, the influence of general roughness change was clearly inferior (average wind direction
using the measured ACR and local meteorological statistical data, including Weibull parameters and occurrence frequencies of each wind direction
, the exceedance probabilities will be calculated for all respective wind directions
, and the overall probability distributions are summarized as a function of a series of specified ACR values for each investigated model orientation.
Dependence of measured concentrations on wind direction
is given in Figures 4 and 5.
