The ocean temperature plays a crucial role in the global climate system, ocean currents and for marine habitats. It varies depending on depth, geographical location and season. Not only does the temperature differ in seawater, so does the salinity. Warm surface water is generally saltier than the cooler deep or polar waters. [1]
A thermocline (also known as the thermal layer or the metalimnion in lakes) is a distinct layer based on temperature within a large body of fluid (e.g. water, as in an ocean or lake; or air, e.g. an atmosphere) with a high gradient of distinct temperature differences associated with depth.
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.
Pamela Sweeney, senior water scientist at Miami-Dade County’s Department of Regulatory and Economic Resources, said the latest sea surface temperature charts are concerning, and that leaders are ...
Surface temperatures in the western North Atlantic: Most of the North American landmass is black and dark blue (cold), while the Gulf Stream is red (warm). Source: NASA The Gulf Stream is a warm and swift Atlantic ocean current that originates in the Gulf of Mexico and flows through the Straits of Florida and up the eastern coastline of the United States, then veers east near 36°N latitude ...
Much of the year's 61.9 inches (1,570 mm) of rainfall occurs during this period. Extreme temperatures range from 27 F [3] on February 3, 1917, [4] to 100 °F on July 21, 1942, (−2.8 to 38 °C), the only triple-digit (°F) reading on record; [5] the more recent freezing temperature seen at Miami International Airport was on December 25, 1989.

Higher water temperatures allow storms to intensify quicker, and ocean temperatures of at least 26.5°C (79.7°F) are needed to maintain a tropical cyclone. ... (30 cm) of rain, skimming the ...
The winds drive surface water to the right of the wind flow, that is offshore, which draws water up from below to replace it. The upwelling further cools the already cool California Current. This is the mechanism that produces California's characteristic coastal fog and cool ocean waters. As a result, ocean surf temperatures are much colder ...
