Description :
Here an attempt has been made to explore this dynamic aeolian process using a new method for monitoring the diurnal pattern of blowing sand. This technique involves detecting blowing sand with a fast responding piezoelectric saltation sensor to determine the movement of saltating grains and its temporal variability. Measurements taken over a seven-month period on the high plains of the Llano Estacado of West Texas and eastern New Mexico suggest that sand movement tends to occur more frequently during daylight hours with a peak in aeolian activity occurring in the afternoon between 14:00 and 15:00 Local Standard Time.
