A Catalina eddy is rarely prolonged. As the heat over the deserts causes air to rise, the resulting pressure gradient and increase in the normal onshore winds causes the vortex to dissipate. The result is the common local weather forecast calling for "late night and early morning low clouds and fog, followed by afternoon sunshine and sea breezes."
The Santa Anas are katabatic winds (Greek for "flowing downhill") arising in higher altitudes and blowing down towards sea level. [7] The National Weather Service defines Santa Ana winds as "a weather condition [in southern California] in which strong, hot, dust-bearing winds descend to the Pacific Coast around Los Angeles from inland desert regions".
Winds of the appropriate direction and strength to induce upwelling are more prevalent in the presence of Eastern boundary currents, such as the California Current. [3] Phytoplankton production is dramatically increased in these areas because the nutrient-rich water lying below the pycnocline is relatively close to the surface and is thus ...
Various Native American peoples occupied the lands in and around the Southern California Bight for tens of thousands of years before the arrival of Europeans. When Spanish explorers arrived in the 16th century the Chumash people occupied the northern coastal region of the bight, as well as the four Northern Channel Islands, [4] and the Tongva (or Gabrieleño) occupied the Los Angeles Basin and ...
Prevailing winds are strongly influenced by Earth's overall atmospheric circulation, in addition to smaller-scale and shorter-lived weather phenomena. In meteorology, prevailing wind in a region of the Earth's surface is a surface wind that blows predominantly from a particular direction. The dominant winds are the trends in direction of wind ...
The most popular theory holds that the Algodones Dunes were formed from windblown beach sands of Lake Cahuilla. The prevailing westerly and northwesterly winds carried the sand eastward from the old lake shore to their present location which continues to migrate southeast by approximately one foot per year.

A San Diego lifeguard raft was unable to reach the person before they died, the agency said, according to a report from AP. Nearly 50 people evacuated from cliffside community Tuesday 6 February ...
The Spanish ships San Antonio and San Carlos landed ship's boats at the site in 1769, looking for fresh water on the San Diego River, on their San Diego expedition. San Antonio arrived in San Diego Bay on April 11, 1769, and San Carlos on April 29. They came ashore on May 1, 1769, and set up a base camp on May 14.
