As a result, ocean surf temperatures are much colder in summer long the Pacific coast than the Atlantic coast at the same latitude. For example, the average July SST (sea surface temperature) at New York City at 40.7°N is 73 °F (23 °C), while at the same latitude in Eureka, CA is 57 °F (14 °C). As such, ocean surf temperatures are rarely ...
A wet-bulb temperature at 500 hPa in a tropical atmosphere of −13.2 °C (8.2 °F) is required to initiate convection if the water temperature is 26.5 °C (79.7 °F), and this temperature requirement increases or decreases proportionally by 1 °C in the sea surface temperature for each 1 °C change at 500 hpa.
Sea surface temperatures along the coast are generally 52–58 °F (11–14 °C) year-round. [3] [4] When the marine layer encounters the colder waters along the California coast, it cools to its dew point, and if small particles called condensation nuclei are present, liquid water drops will form.
It is usually between 1 millimetre (0.04 in) and 20 metres (70 ft) below the sea surface. Sea surface temperatures greatly modify air masses in the Earth's atmosphere within a short distance of the shore. The thermohaline circulation has a major impact on average sea surface temperature throughout most of the world's oceans. [10]
Sea Surface Temperature Analysis clearly shows highest temperatures (28 °C (82 °F) and more) along the 10°N latitude and not along the geographic equator. The reasons are the two cold currents: California Current at Northeast and Humboldt Current along the equatorial line.
The National Weather Service issued high surf advisories Thursday morning for Northern California, with 20-to-30-foot waves expected through Sunday.
This is an example of quality control and monitoring of sea surface temperatures measured by ships and buoys, the iQuam system developed at NOAA/NESDIS/STAR, [3] where statistics show the quality of in situ measurements of sea surface temperatures.
Average sea surface temperature along the NPC can range in the winter from 45 to 61 °F (7.2-16.1 °C) and in the summer months 64 °F-74 °F (17.8-23.3 °C). As it flows from west to east, the latitudinal extent of the NPC increases so much that it spans some 20 degrees of latitude east of the dateline.
