Seeding elements
Elements are moved with the ocean current, in addition to a fraction of the wind speed (wind_drift_factor). This factor depends on the properties of the elements. Typical empirical values are: - 0.035 (3.5 %) for oil and iSphere driftes - 0.01 (1 %) for CODE drifters partly submerged ~0.5 m As there are large uncertainties, it makes sense to provide a statistical distribution of wind_drift_factors
Using a constant value for all elements:
wind_drift_factor = 0.03
Giving each element a unique (random) wind_drift_factor
wind_drift_factor = np.random.uniform(0, 0.06, 2000)
