Description:
Hourly wind recordings at Davis and Grimes, California, revealed that spraying operations by aircraft in summer can frequently be extended beyond the customary sunrise hours without damage by drift to adjacent crops susceptible to the spray material. The data permitted scheduling spraying according to wind types. These wind records also revealed noteworthy meteorological peculiarities. The influx of the marine air beginning in the afternoon lasts almost all night, only being replaced by the opposite flow after sunrise. This indicates that the often heard “land and sea breeze” term is not appropriate, and that rather a monsoon flow tendency prevails. It is suspected that the daily variation is primarily influenced by a daily cycle in strength and northward extension of the Arizona Low.
