What is marine meteorology?

Marine meteorology involves both the atmosphere and the ocean, so it is a research field of atmospheric science and marine science. Because most of the earth's surface is covered by ocean, seawater has different physical and chemical properties from land, which determines the important position of ocean in marine meteorology research. Research content of gale forecast at sea 1, marine meteorological observation and experiment. Including the study of marine meteorological observation methods, the development of marine meteorological observation instruments and devices, and the investigation and study of marine meteorology in local or large-scale sea areas. 2. Ocean weather analysis and forecast. Study marine weather and weather systems and their closely related marine phenomena, including the mechanism analysis and forecasting methods of sea fog, sea ice, waves, storm surges, tornadoes at sea, tropical storms and extratropical cyclones (see marine hydrometeorological forecast, weather analysis and weather forecast). 3. Interaction between ocean and atmosphere. The air-sea interaction studied in marine meteorology is mainly the transport and exchange process of various physical quantities between the ocean and the atmosphere, including heat, momentum (or kinetic energy), water vapor, gas and charge and their temporal and spatial changes, observation and theory of air-sea boundary layer, and large-scale air-sea interaction (see turbulent transport of sea surface atmosphere and air-sea relationship). In the scope of large-scale air-sea interaction, the generation of atmospheric circulation and ocean circulation and their corresponding relations, the influence of ocean western boundary current (Gulfstream and Kuroshio) on the weather, weather system and climate in its adjacent waters, the influence of tropical oceans on local and even global atmosphere and climate (such as El Ni? o phenomenon), the increase of carbon dioxide content in the atmosphere, the role of the ocean in this process and its influence on climate change are emphatically studied. In the above fields, the relationship between some phenomena of ocean and atmosphere has been revealed, and a number of research results have been obtained, which is of great value to long-term weather forecast and climate forecast. Derivative discipline marine meteorology is a discipline gradually developed from production activities, and the following branches are derived: 1, maritime meteorology. Study the meteorological problems in navigation, especially the decision-making and tracking navigation of marine meteorological route-the optimal route, so as to provide meteorological services for navigation. 2. Fishery meteorology. To study the meteorological problems in the fishing and breeding of aquatic resources and provide meteorological services for fishery production. 3. Salt meteorology. The meteorological problems in salt making, such as tidal absorption, brine accumulation, salt field evaporation, wind and precipitation, were studied. 4. Port meteorology. Study the weather and climate problems in port design and port production.
