; No need for user to explicitly load. function wind_component ( wspd : numeric, ; float, double, integer only wdir : numeric, opt : integer ) A variable of any dimensionality containing the wind speed. Array size and shape must match wdir. A variable of any dimensionality containing the meteorological wind direction.
The characteristics of wind speed, wind direction, and wind profile are crucial factors influencing the efficiency of wind resource and the accuracy of parachute landing operations. Regional differences in underlying surface types significantly affect these meteorological parameters.
These directions are typically expressed in units of degrees, φ (deg), but can either be in the interval -180° to +180° or 0° to 360°. The wind vector azimuth and meteorological convention direction are related by: subtracting 360° where appropriate in order to keep the values within the desired range.
As shown in Fig. 1, it is evident that at the altitude of 10 m, the prevailing wind direction is northeast, with a frequency of 14.55 % and an average speed of 1.71 m/s. This is followed by north-northeast (13.02 %) and east-northeast (11.91 %), with corresponding average speeds of 1.61 m/s and 1.54 m/s, respectively.
In winter, the profiles exhibit greater variability, with higher wind speeds near the surface, a decrease with altitude up to 200 m, a subsequent gradual increase to a peak (around 500 m), followed by a slow decline. During the summer (June to August), the profiles take on an inverted bow shape, with wind speed steadily increasing with height.
For the inland plateau surface, the dominant wind direction remains southwest, regardless of altitude. For the coastal surface, the dominant wind direction changes from east at lower altitudes to south-southwest at higher altitudes.
The global solar storage container market is experiencing explosive growth, with demand increasing by over 200% in the past two years. Pre-fabricated containerized solutions now account for approximately 35% of all new utility-scale storage deployments worldwide.
