The study of the physical properties of the ocean, including but not limited to temperature, salinity, and ocean currents, and of the physical processes that determine those properties.
Industry:Weather
The study of the interaction between matter and radiation. Since the energy levels in all atoms and molecules are discrete (quantized), the absorption or emission of radiation occurs at distinct energies (frequencies) characteristic of a given chemical. The energy levels probed may be rotational (microwave region), vibrational (infrared region), or electronic (visible or ultraviolet). In mass spectroscopy, molecules are ionized and the different masses selected by use of an electric or magnetic field. Many spectroscopic techniques have been used to identify molecules or atoms in the atmosphere.
Industry:Weather
The study of the atmosphere and weather using radar as the means of observation and measurement. One of the branches of physical meteorology, it shares much in common with cloud physics and, more generally, atmospheric remote sensing. For essays on the history of radar meteorology and research reviews, see Atlas (1990).
Industry:Weather
The study of the formation and precipitation of liquid and solid hydrometeors from clouds; a branch of cloud physics and of physical meteorology.
Industry:Weather
The study of the chemical and physical changes occurring when a molecule or atom absorbs light. These can include photodecomposition, fluorescence, chemiluminescence, and quenching of the excited state. The atmosphere can be considered as a complex photochemical reactor, the chemistry of which is driven by the visible and ultraviolet radiation emanating from the sun.
Industry:Weather
The study of regional and seasonal variations in the manner of propagation of radio energy through the atmosphere.
Industry:Weather
The study of natural remanent magnetization in order to determine the intensity and direction of the earth's magnetic field in the geologic past.
Industry:Weather
The study of past climates throughout geologic and historic time (paleoclimates), and the causes of their variations.
Industry:Weather
The study of climate from the perspective of atmospheric circulation, with emphasis on the connections between circulation patterns and climatic differences. The common approach is to determine distinct categories of synoptic weather patterns and then to assess statistically the weather conditions associated with these patterns. The term, which refers to synchronous weather systems such as cyclones and anticyclones, originated during the 1940s when military services became concerned with the climatology of weather types and its implications for transportation. While dynamic climatology is often global in scope, synoptic climatology generally deals with hemispheric or local climates.
Industry:Weather
The study and analysis of synoptic weather information (synoptic charts, synoptic weather observations).
