211 results about "Sea surface temperature" patented technology

Sea surface temperature (SST) is the water temperature close to the ocean's surface. The exact meaning of surface varies according to the measurement method used, but it is between 1 millimetre (0.04 in) and 20 metres (70 ft) below the sea surface. Air masses in the Earth's atmosphere are highly modified by sea surface temperatures within a short distance of the shore. Localized areas of heavy snow can form in bands downwind of warm water bodies within an otherwise cold air mass. Warm sea surface temperatures are known to be a cause of tropical cyclogenesis over the Earth's oceans. Tropical cyclones can also cause a cool wake, due to turbulent mixing of the upper 30 metres (100 ft) of the ocean. SST changes diurnally, like the air above it, but to a lesser degree. There is less SST variation on breezy days than on calm days. In addition, ocean currents such as the Atlantic Multidecadal Oscillation (AMO), can effect SST's on multi-decadal time scales, a major impact results from the global thermohaline circulation, which affects average SST significantly throughout most of the world's oceans.

Passive Microwave Assessment of Human Body Core to Surface Temperature Gradients and Basal Metabolic Rate

InactiveUS20120029369A1Enhances ability to quantifyEnhances to mapThermometers using value differencesBody temperature measurementDiseaseHuman body
A passive microwave thermography apparatus uses passive microwave antennas designed for operation, for example, at WARC protected frequencies of 1.400 to 1.427 GHz and 2.690 to 2.70 GHz (for core body gradient temperature measurement) and 10.68 to 10.700 GHz or higher microwave frequency (for surface body gradient temperature measurement) and a related directional antenna or antenna array to measure microwave radiation emanating from an animal, especially, a human body. The antennae may be radially directed toward a point within or on the surface of a human body for comparison with known temperature distribution data for that point and a given ambient temperature. Each frequency band may provide a plurality of adjacent noise measuring channels for measuring microwave noise naturally emitted by the human body. The apparatus measures short-term changes in, for example, core and body surface temperatures to establish a basal metabolic rate. Changes in core body temperature may be stimulated by the administration of food or certain organic and drug-related substances or stress to induce a change in basal metabolic rate over time. These changes correlate directly with a human subject's metabolism rate at rest and under certain dietary constraints and can be used to determine courses of treatment for obesity, metabolic disease, and other disorders. The apparatus can also be used to remotely monitor patients and subjects without physical contact.
