Interannual Variability in the Coastal Zones of the Gulf of California

Few studies have explored the details of climatology in Gulf California (GoC) coastal zone, a region characterized by robust land–sea breeze circulation that results from land heating on both coasts GoC. Using hourly historical observations automatic weather stations (AWSs) 2008 to 2018, we performed harmonic and empirical orthogonal function analyses describe several characteristics are regularly monitored GoC zone. The included air temperature (°C), relative humidity (%), atmospheric pressure (hPa), wind intensity (m s−1), direction (°). National Water Commission (CNA) provided records for located along coast revealed an intense annual and, lesser extent, interannual signal all characteristics. presence synoptic patterns forces seasonal intraseasonal variations occur. In summer, tropical systems increase variability, mainly at eastern mouth Some display this until cold season arrives with passage winter systems. Finally, found variability could be associated El Niño–Southern Oscillation events.
