Atmospheric dust intrusions from the peninsular region into the Northern Gulf of California: case study

Abstract Through atmospheric transport, coming from the mainland, an important amount of dust arrives to surface waters open-ocean regions and many coastal zones. Semi-arid desert areas tend act as sources dust. The Gulf California (GC) is one most productive marginal seas world, it surrounded by semi-arid deserts located in Baja Peninsula, United States, Sonora (Mexico). Dust fluxes BCP during summer are relevant due biological impact on Gulf. In northern region BCP, meteorological events have not been well studied. These known popular slang "El Torito". characterization a event that originated Peninsula (BCP) June 14, 2016, presented. Meteorological variables (from North American Regional Reanalysis -NARR), daily sea temperature, aerosol optical thickness MODIS) used explain genesis, used. Results suggest temperature fluctuations Pacific Ocean off coast generate changes hydrometeorological (wind, relative humidity, pressure) can give rise events. 14 storm originates San Felipe disperses aeolian California, shown images trajectories simulated with HYSPLIT model, which establishes vertical distributions predominant heights between 0 500 m.
