Extreme Wind Speed Modeling across Garoua City and Implications Assessing for the Flight Activities

In this paper, we analyze the directions, intensities, spatial and temporal distributions, variability, and trends of extreme wind events using wind speed data that span between the 2012-2017 periods in Garoua City. The results obtained show that the wind blows a little almost from all directions and the dominant direction is from the North-West with more than 40% of winds in this direction, the dominant axis is SE-NW with more than 55% of winds in this axis and the annual mean wind speed at a height of 10 m is 5 m/s in 2014. It was further shown that it decreased until it was canceled in 2017 characteristic of the calm wind. In this context, the forecast of the wind speed variability (intensities and directions) becomes very crucial. This fact denotes a problem for lighter aircraft, whose crosswind rates are lower.
